Why It’s Important To Service Your Machine Regularly

Employers have a legal obligation to ensure correct maintenance of machinery in the workplace. This helps to reduce any risks as a result of unexpected failures and helps to keep the work-force safe.

On top of this, there are several good reasons to keep your machine serviced on a regular basis.

Prevention of faults or breakdowns

Untimely breakdowns caused by underperforming equipment will have a negative impact on any company. Here are just a few of the issues that occur as a result of faulty equipment:

- Unnecessary downtime
- Expensive part replacements
- Costly repair bills
- Reduced productivity

Having a regular service significantly reduces the effects of faulty machines as they ensure that parts are still in good working order. They identify and rectify faults during a routine maintenance time schedule, and not in the middle of production!

Catching failures before they become a problem

Proactive maintenance is the key to anticipating when there will be a problem with the machine (and being able to take action to avoid inconvenient breakdowns or repair costs in the future). To prevent costly issues from happening, it’s important to organise routine services on your machine or equipment.

A good machine service plan should provide:

- A set time for work to be carried out – not in the middle of your busiest period.
- An overall evaluation of your machine by experienced engineers.
- Preventative measures to maintain the smooth running of your equipment.
- Identification and supply of required parts.
- Parts replacement where necessary.

Keep your machine running efficiently

When your machines are running effectively, your plant is running smoothly. A well-run plant enjoys a high level of productivity which enables companies to meet supply and demand which in turn leads to greater reliability. Overall, a reliable and productive plant is a profitable one.

FIBC Dischargers - An all Important Piece of Equipment for the Chemical Industry

F.I.B.C dischargers, or ‘Big Bag’ dischargers as they are also known, are important for the economic, dust-free depositing of material onto a production line – and are particularly important for a number of operations within the chemical industry.

What is an FIBC, ‘Big Bag’, ‘Bulk Bag’ or ‘Super Sack’?

FIBC is an abbreviation for ‘Flexible Intermediate Bulk Container’. Used primarily for transporting goods in quantity, these large bags are composed of a strong, plastic-based, flexible fabric and can hold up to weights of approximately 1000kg. They are also lightweight (and therefore can be suspended). Typically, they are manufactured with either one, two or four loops for efficient handling purposes and conveniently fit on to the equipment for many process industries.

What is an FIBC Discharger?

These important pieces of equipment can be used in a variety of industrial applications from transporting fertilisers to dispatching chemical materials by mass. Other sectors that use FIBC dischargers as an integral part to their production line include:

• Food products
• Fertilisers
• Pharmaceuticals
• Grains
• Construction materials

What are the Main Advantages of Using FIBC Expulsion Machines in the Chemical Industry?

No Contamination

Safe handling can be a significant concern for many industries. One of the key benefits of using FIBC dischargers is that the Big Bag can be lifted straight from the forklift or other transport machinery onto the discharger with minimum contamination.

Dust Control

Again, it cannot be reiterated enough how important it is to ensure that cargo in the chemical industry is not contaminated. FIBC Dischargers ensure that the chute section wraps around the lower outlet to ensure that that unwanted dust cannot contaminate the chemicals being transported.

Safe Handling

This is potentially one of the most important advantages of using Bulk bag dischargers. Depending on the chemical cargo, certain loads may be particularly dangerous in terms of weight and also human handling. Heavy bags are easily held up by the dischargers and potentially harmful chemicals remain at a safe distance for employees.

Why Are Vibrating Sieves So Important To The Food, Snacks And Confectionery Industry?

In the twenty first century, vibrating sieves are used to break down oversized lumps and improve the quality of ingredients during the production of food. Although sieving has always been a part of our culinary heritage, it was not always so easy...

The evolution of the sieve – why does the food industry use vibratory sieve systems?

In the studies of ancient technology, sieving was one of most important operations to exist within the kitchen. As early as ancient Egypt, sieves were constructed using reeds, rushes or papyrus. Transcending through centuries, the construction of sieves evolved from basic earthy products into metal mesh.

Fortunately for us, the days of constructing sieves from leaves are over. Mass commercialisation means that the food industry is always innovating and developing new and exciting methods to get produce to consumers quickly - and sieves play an integral part.

The importance of the vibrating sieve in food production

An extensive amount of food, snacks and confectionary companies rely on sieving as part of a production process. The use of vibratory sieves ensures accurate separation of products and is essential for quality assurance in the manufacturing of food.

Benefits of using vibrating sieves include:

- Lumps of product are broken down by the sieving mesh
- Faster sieving means higher throughputs
- Reduced sieve blinding and blockages reduces cleaning requirements

What type of vibratory sieve should you use if you are looking to improve your confectionary or bakery production line?

- Vibratory Batch Sieve - This style of sieve is excellent for any food production facility, large or small. Not only is it robust, but it is compact and manoeuvrable. The batch sieve is a versatile system that has been used in applications including sieving flour, sugar, salt and biscuit crumbs, as well as separating nuts and raisins from melted chocolate bars for reworking. The compressed design makes it ideal for laboratories for food testing and bakeries.
- The Gough Bakery Sieve - The clue is in the name and this expertly designed machine is at home in a bakery setting. The purpose of the bakery sieve is to be able to withstand large and heavy batches of ingredients, like flour and sugar. Its vibrating sieving mesh is able to process any product quickly and efficiently, removing lumps to leave quality ingredients. The simplicity of this machine minimises maintenance requirements, leaving more time for processing product. The enclosed sieving station is designed for dust control, which means it will capture any loose particles in order to follow the latest HSE legislation that aims at preventing asthma in the baking industry.

Bucket Elevator Innovation - 4 Bucket Elevator Projects That We’ve Worked On In 2016

At Gough Engineering, we design bucket elevators and bucket conveyors for global and national companies - it’s safe to say we know everything there is to know about bucket elevators! 2016 was an exciting year for us - throughout the year we worked closely with many food, snacks and confectionery businesses to create bespoke bucket elevators for several production processes. From crisps, to nuts, to pet food – we’re able to create the ideal production process. Here’s just a handful of exciting bucket elevator projects worked on at Gough Engineering in 2016…

A Chewing Gum Company in the UK

With an established UK history, this company initially became a household name through launching its spearmint gum in 1911. This year, we have supplied two Gough M Series Swinglink Bucket Elevators to replace existing Econ-o-Lift Bucket Elevators (that Gough supplied back in 1990 for the handling of sugar free pellets). The new machine is to be in accordance with the following schedule and specification: one inlet, four tipping stations – three off pneumatic with selective tip and one off fixed tip and a throughput of 3,000 kg an hour.

A Snack Foods Production Company in Malta

The businesses flagship product is a delicious crisp savoury snack. Gough Engineering supplied the company with a Swinglink Bucket Elevator with 3 discharge points over a crisp packaging line. The crisp company was so pleased with its production process equipment that discussions have already begun surrounding a second bucket elevator for another packaging line.

A Pet Foods Manufacturer in Suffolk

This customer manufactured and supplied specialist pet food for small animals. They approached Gough Engineering looking for production process equipment to elevate and convey pet food product into a weigh hopper (5,150 mm above the ground). The company already had an old Gough elevator that it had purchased second hand (and had been in production for years!). To keep up with demand and streamline production in its congested facility, they have decided to invest in a brand new machine to fit a throughput of 5,400 kg an hour.

A Snack Foods and Confectionery Company in West Yorkshire

They are the only pistachio production company in the UK. We supplied two Gough ‘S’ series Swinglink Bucket Elevators to handle various nuts (pistachios) in accordance with the following schedule and specification: one inlet, two tipping stations – one pneumatic tip and one fixed tip, one with a throughput of 1,500 kg an hour, and another with 2,000 kg an hour. An extended in-feed hopper was also used to receive product from the existing feed conveyor and minimise product spillage.

What's Gough Been Working On Lately?

We’ve been busy working with a chemicals company in Warrington, world leaders in the production of potassium chloride. The company's unique manufacturing processes helps to provide potassium chloride products for the pharmaceutical and foods industries worldwide.

The company had been working with Silica gel and required a conveying system to receive product from four off-gel wash vessels before discharging onto a conveyor once washed. It was important for us to prevent any unwashed product leaking and contaminating washed product.

This was a tricky task! But our sophisticated range of equipment means that we were able to supply four grade 316 stainless steel belt conveyors to reach a throughput of 7,326 kgs an hour.

The system was customised to manage the risk of leakage – we did this by designing a heavy pneumatic side cover to block off the conveyor inlets. The framework was built of 316 stainless steel so as to fight corrosion against chloride. The conveyor itself was at an inclined angle so that the product would be going backwards as it was being conveyed.

What are the benefits of a customised conveyor system from Gough Engineering?

Belt conveyors are a standard solution for moving bulk or unit load products through manufacturing and processing environments. Our extensive experience means that we’re great at working with businesses to create a bespoke conveyor system and manage any risk (such as loss or damage to product).

What Is The Difference Between A Sieve And A Screen?

Even in the business of manufacturing and supplying vibratory sieving and screening equipment, the terms 'sieve' and 'screen' are pretty interchangeable, in fact I don't think I have every really heard of someone being pulled up about using either, but technically speaking, there is a difference.

Both are very similar (which is why they are often thrown in together), generally consisting of a wire mesh of a specified aperture with some sort of vibration applied; to separate a product into two different groups based on particle size. One separation of the product is generally considered the 'good' product, and the other discarded or reprocessed. It is a simple process used for countless applications in dozens of sectors.

But, what is the difference between a sieve and a screen?

- A sieve is used to process individual batches of product. At Gough, we sell a lot of sieves to baking companies who use them to sift and check screen bags of flour and other ingredients before they are mixed during production. The sieving process sifts out lumps and improves the quality of the flour for better final produce, as well as adding a measure of safety by separating out any debris that may have found its way into the product.
- A screen is used on a continuous flow of product. Screens are installed into production streams to remove lumps and oversize particles, or allow fine particles and dust to be separated out, cleaning up the final product. We have supplied screen systems to chemical manufacturers to screen off lumps before the final bagging process, and to crisp manufacturers to remove small broken crisps and crumbs before packing. Screens come in both circular and linear configurations; deciding which is best for a particular process is usually determined by the type of product being processed, the throughput required, and space limitation within a facility.

How To Design A Bucket Elevator?

A vast number of organisations rely on bucket elevators for conveying and elevating dry products – bucket elevators contribute towards ensuring a smooth operation in the transportation of materials such as:

- Cereals
- Sweets
- Granules
- Pellets
- Powders

But what should be considered during bucket elevator design?

First of all, it is essential to realise that each bucket elevator design is produced with a particular application (such as food production) and material in mind – a designer should consider both the material and application thoroughly.

In terms of material, the following must be considered:

- The weight of the material.
- The texture of the material.
- The bulk density.
- The moisture level.
- The size of the material (width and height).

It is also advised that only free flowing materials are conveyed or elevated – this is to prevent a build-up of product (sticky materials can be very difficult to convey!).

Determining the layout and construction of your bucket elevator.

Determining the appropriate layout, dimensions and construction materials are crucial components of bucket elevator design. Questions that a designer must answer include:

- Can the bucket elevator achieve the required product throughput rate (defined by the bucket capacities multiplied by the conveying speed)?
- Will the chain be strong enough to elevate the weight of product to the required height?
- Will the bucket elevator physically fit into the production facility, as often there areas are already filled with equipment?

Different types of bucket elevator design.

There are multiple types of bucket elevator to consider too - the type of bucket elevator designed depends on the application. For example:

- Swinglink bucket elevators – this bucket elevator is a chain and pendulum type system and can be used to convey a range of products and include multiple inlets and discharge points.
- Econ-o-Lift bucket elevators – this should be used to convey hoarse and abrasive materials in challenging environments.
- Horizontal bucket conveyor – this is a low maintenance alternative to a conventional belt conveying system.

At Gough Engineering, we have over seventy years of experience designing bespoke bucket elevators across a wide range of industries. We have the knowledge and experience to consult a wide range of organisations on the suitability of bucket elevators in their overall operation.

How Do Vibratory Feeders Work?

At Gough Engineering, we provide bespoke vibratory feeders. Vibratory feeders are used to achieve a controlled and even flow of materials through a section of a production line. Vibratory feeders are relatively simple to operate and maintain.

But how do vibratory feeders work?

The feeders use vibrations to convey materials along a production line or into a process point. The drives of the feeders are angled to generate a rapid series of forward hops that individually are imperceptible to the naked eye, but combine to create a continuous product flow that is even able to move product up a shallow incline. The specifics of how the feed is generated depend on the system chosen, which is usually determined by the application. The types of feeder include:

- Heavy duty twin motor feeders
- High frequency electromagnetic feeders

Heavy duty feeders use a twin motor with coil spring suspension. The feeding action is achieved due to the vibration of the feeder tray, generated by the two sets of out-of-balance weights spinning at over 1,000 rpm. The motors are angled to send the waves of momentum through the product to create the forward hops.

High frequency electromagnetic feeders generate vibrations using an electromagnetic coil and magnet. The electromagnetic coil is attached to a base and the magnet is attached to the feeder tray. The electromagnetic coil turns on and off at a high frequency attracting the magnet when it is on, which then springs away on the flat suspension springs when it is off, creating the hops to move the product.

Vibratory feeders at Gough Engineering.

At Gough Engineering, vibratory feeders are custom manufactured from proven designs. We manufacture both high frequency electromagnetic and heavy duty twin-motor vibratory feeders.

The electromagnetic feeders give greater control over the product, providing either a continuous feed, or a feed that can be regularly stopped and started for a more measured throughput. These feeders are generally used for applications that demand careful handling, such as in food processing environments. The twin-motor feeders are designed to give a continuous, even flow of product. These feeders are generally used for more heavy duty applications, where high throughputs are required over gentle handling.

All feeders are designed to be simple to operate, and once set up, require virtually no maintenance. Should you require any more information about our vibratory feeders, do not hesitate to contact us.

Wood Pellet Screening System Case Study

The Task: One of the UK’s largest manufacturers and distributor of pet supplies contacted Gough Engineering looking for a product screening solution. The company primarily manufacture a range of cat litter and animal bedding materials, and had concerns about an unacceptable amount of dust and fine particles being bagged up with their product. They required an efficient and reliable means of separating out good wood pellets from the dust at a fast enough rate to meet their production requirements, before the product was bagged up and made ready for sale.

The Solution: After a visit from a Gough Applications Engineer and discussions with the customer about what they wanted the new screening system to achieve, we developed and manufactured a single deck vibrating Linear Screen to gently shake the dust loose from the wood pellets before discharging through separate outlets. The Linear Screen included a 1,100 mm wide by 2,500 mm long screening area to sieve the wood pellets from the dust at a rate of 5 tonnes per hour.
The unit was designed as a low-level unit to allow it to fit beneath the customer’s pre-existing product holding bin, with an enclosing top cover to prevent any dust escaping into the surrounding production facility. Once screened, good wood pellets discharged into a material collection pump prior to being conveyed to the company’s bagging systems, whilst all dust and fine particles are discharged into a separate collection bin.

The Result: The company has been very pleased with the results and overall performance of the Gough Vibratory Linear Screen, and were impressed and pleasantly surprised by the low-noise level of the unit during its operation. After successful sales of their newly screened products, the company is currently considering the purchase of a second Linear Screen to expand their production.

Waxed Beads Screening System Case Study

The Task: A pharmaceuticals company in Canada required a screening system which would prevent spillage of product. The manufacturing process for waxed beads includes a percentage of the product falling outside of the size specification to move onto the next process. The product would be screened in 350kg batches into oversize, acceptable product and fines. Using conventional screening, the meshes would blind very easily and operator intervention was critical to encourage the product to separate. This meant the process would take up to 6 hours to screen and there would be a further downtime for cleaning before the process could be repeated.

The Solution: Gough merged the technology of conventional circular screening with Ultrasonic aided alternative frequency. The application included the addition of a resonator ring and a controller to the deck and mesh required for the screening process.

The Result: The system we provided had a mesh that always remained un-blinded and improved throughput by 6 times. Cleaning in between operations was now at a minimum, and batches were screened more accurately with no manual intervention required whatsoever.
