Vibratory Conveyor FaQ

What is a vibration conveyor?

Vibratory conveyors (or shaker conveyors) are used for high-product throughputs and bulk handling applications. They are used primarily in industrious applications where a high level of hygiene is required, e.g., food production, pet food production and pharmaceuticals. They have an extensive range of uses and can be designed with an open or enclosed tray as well as a full tubular design. They are powered through e-mag coil drives and motors, and they have a variable speed to suit the product and factory requirements.

How do vibratory and shaker conveyors work?

Our vibratory conveyors work by pulsing an electromagnetic drive vibrating the conveyor tray using leaf springs, transferring the product stream along the upper conveyor tray. Our linear action vibratory drives can be used for various complementary functions, including heating, cooling, grading, feeding, settling, air knife applications, vacuum extraction, weighing and packing, laning to robotic pick and place systems, to name but a few.

The majority of our e-mag vibro conveyors have an open design rectangular pan, and our drives can be located in a variety of positions, including underslung. The leaf springs/fixtures are attached to the conveyor’s mounting blocks; generally, side situated for easy access. The type of leaf spring used is dependent upon the product, conveyor size and throughputs.

What are the main vibro conveyor applications?

In most cases, vibrating conveyors can be used in place of belt conveyors for hygienic handling of products, processes, or food streams. The industries where they are most used is in food production, pet food production and pharmaceuticals, where the machinery needs to be easily cleaned with no places for bacteria to accumulate.

What are the differences between a vibratory conveyor belt and a vibratory conveyor?

A vibratory conveyor uses an electromagnetic drive to vibrate the product along the conveyor to the following processing stage. A belt conveyor uses a belting type material, mechanical motor driven with all of the associated maintenance that goes with a belt conveyor system.

Belt conveyors do not disperse or settle product, and if loaded in a ‘pyramid’ at one end, it will remain a ‘pyramid’ whilst being transported to the end of the belt conveyor. Vibratory conveyors disperse, spread, evenfeed, align, grade into fractions, to name but a few feasible applications.

Belt conveyors have a low initial purchase cost, usually 30% lower. However, the maintenance cost is much higher as there are more parts to replace on belt conveyors. On vibro conveyors, the trays do not need to be replaced (unlike belting materials). It is usually more economical to use a vib conveyor as they have a lower cost of ownership. We have produced an entire case study on the differences here:

What is a vibratory cooling conveyor?

As the vibrating conveyor tray is formed from metal, you can then perform multiple applications on the same conveyor. A cooling conveyor cools the product on the tray as it passes from the processing stage to the next through added refrigeration integration. As the product vibrates, it is distributed across the conveyor width to form a monolayer, creating more effective and uniformed cooling.

What is the ideal vibratory conveyor frequency?

The magic number for a Cox & Plant Vibratory Conveyor is 23.5Hz.

All of our machines have an amplitude gauge on the side of the tray to enable a visual check your conveyor is performing to its specified duty. The optimum frequency setting up is in our handbook supplied with each machine, together with vodcasts on our client hangout area.

What is a vibratory crosshead feed conveyor?

A Vibratory Multihead Conveyor is specially designed to feed a measured delivery of the product to the scale. The weigher vibro conveyors have a variable speed synchronised with the multihead to deliver the optimum delivery of products on a call on-demand principle. We call this our’ parent & child software’.

Most common is feeding a CCW or Multihead weigher to make sure there is an even spread of produce across the scale head, so the perfect algorithm of 4/5 buckets are selected, making the weighing process even more precise.

Using our powered circular or spigot discharge vibration and synchronisation technology, we can exceed most customers specification, drastically improve your packing line in addition to the best ROI of reducing product giveaway.

What is a vibratory inspection conveyor?

Vibratory Quality Assurance Inspection Conveyors are added to the line for quality control purposes. The vibratory technology will create an even spread of product spanning the conveyor tray’s entire width, allowing the quality control teams to remove bad or unwanted product into the rejection channels. The channels are an integral part of the design to ensure full equally distributed movement of the product stream.

What are vibrating conveyor leaf springs?

Composite Leaf springs are attached either under the pan or at the side of the conveyor tray either underslung or traditionally mounted on the solid reaction base. The leaf springs/flexures are attached on mounting blocks to the conveyor, always located for easy access should they need to be changed after 5 years plus of hard duty.

Our full range is designed based on your throughput and performance required for your business. With throughputs from 100 kilos to 35,000 kilos per hour, we have the exact offering you need for decades of outstanding, trouble-free performance.

What are the different vibratory conveyor types?

There are many different types of vibrating conveyors as they are very versatile for a plethora of duties. With some clever proven design secrets, these can be used as grading machines, sieves, inspection conveyors, vib conveyors, metering conveyors, laning systems, settling conveyors, de-oiling conveyors, feeder vibratory conveyors and shakers. From weird and wonderful to plain and simplicity in motion, Cox & Plants team have the answer to most of the industries problems.

What is a vibratory tubular conveyor?

The main benefit of a tubular conveyor is that there is no airborne loss when the product is transported. This is particularly important if you have a potentially harmful product if inhaled or if you have an expensive granular product to minimise product giveaway. Tubular conveyors are formed using a whole stainless steel tube, enabling high levels of hygiene are easier to maintain.

Vibrating conveyor troubleshooting

Like all machinery, if it is not serviced or maintained, then they can be some issues. We have developed a set of how-to-videos for our customer base that looks at the most common faults and how to alleviate them.

As there are minimal parts on shaker conveyors, any possible issues generally arise from poor cleaning techniques or harsh chemical use. Leaf springs need to replenish the springs approximately every 5 years (dependant on conveyor usage), and this is the primary consumable, which, if ignored, will result in the vib conveyors underperforming.

Buying a used / second-hand vibratory conveyor

Each piece we produce is tailored to that individual business, the requirements of that particular product in that specific environment, therefore buying second-hand machinery may not be beneficial for your business as it may not convey your products effectively or even be fit for purpose.

What are the different tray types that can be utilised in a design?

Spigot / Circular Discharge

Ideal for feeding a Multihead Scale or with flexible fitting inlets and outlets

Adjustable End Piece

Ideal for feeding a Multihead Scale with products that don’t ‘carry well’ in flight, this will ensure an accurate supply of products typical for mixing applications.

Slotted Discharge

Ideal for product alignment @ 90° to freezers / ovens / dryers / roasters / chill blasters to deliver an even ‘curtain’ of product.

Scarf Discharge

Ideal for feeding an even spread of product @ 90° to the following interface, typically bucket elevators utilise this perpendicular option.

Flat Bottomed Design  

Ideal for feeding a Multihead Scale or with flexible fitting inlets and outlets

Bevelled Exit Discharge

Ideal for feeding a Multihead Scale or with flexible fitting inlets and outlets

Decreasing Width

Ideal for feeding an even spread of product @ 90° to the following interface, typically bucket elevators utilise this perpendicular option.


Our Dustproof conveyor is the solution to alleviate issues caused by product leaching into the working environment. The tube design typically has a maximum filling capacity of approximately 50%.


Ideal for products that require a ‘pinched’ or very narrow discharge to the next process.

Rounded sides / semi-circular

Ideal for light, rounded items, particularly in the confectionery industry where sugar is used in many of the coating processes. As opposed to 90° angled sides, the rounded sides act as a ‘self-cleaning’ medium that eliminates the excessive build-up of sugars as the fresh product pushes the debris along with the product flow to be sieved out as necessary before packing.

Principle of Conveying by Vibration

The tray of a conveyor is driven at a pre described angle, the angle depending upon the type of product being conveyed and its physical characteristics: the angle is usually 20 degrees. In operation the tray moves forward and upward and then returns to its original position. The tray propels the product forward but, since the return stroke of the tray is faster than the gravitational pull on the product, the product falls ahead of the position it occupied at the start of the cycle. As the cycle is repeated, the product moves forward in a series of short hops although to the eye it appears as a continuous uniform motion. Altering the amplitude and frequency of the vibration can vary the nature of the product flow.

What is Vibratory Motion

The vibratory motion is obtained from an electrically driven coil box that passes impulses to the I-piece fixed to the conveyor tray. The coil box transmits impulses to the conveyor tray on the backstroke; the return stroke is obtained from the spring action of the fibreglass leaf springs.

The fibreglass leaf springs are at a predetermined angle to give both forward and upward movement to the vibrated tray enabling the material to be moved towards the discharge end.

Is the Amplitude of Vibration on Vibratory Conveyors Important?

The conveyor is designed to work at predetermined maximum amplitude, which must not be exceeded. In the unlikely event of greater amplitude being required, reference should be made to Cox & Plant Products Limited. The maximum amplitude of any given conveyor can be found marked on the label attached to the reaction base.

Check that the maximum amplitude does not exceed that shown on the label.

The fibreglass leaf springs are at a predetermined angle to give both forward and upward movement to the vibrated tray enabling the material to be moved towards the discharge end.

Is there a certain way to clean the coil drives on the vibratory conveyors?

Cleaning can go from wiping with a clean damp cloth and drying them with a clean dry cloth at the start of every shift will be perfectly acceptable in dry environments. At the high level deep hygiene cleaning regime, our coil drives are tested to IP 69 so even the most energetic hygienist with a 1000 psi hose spray won’t cause any issues to their performance when clean down is complete.
