Waste & Recycling Conveyors

Conveyors for the waste recycling and materials recovery facility (MRF) industry, plus businesses, councils and government.

Businesses, governments and councils are under increasing pressure to grade and recycle waste, with a corresponding increase in the need for materials recovery facility (MRF) conveyors. Central Conveyors have installed various conveyor systems.

Business
In conjunction with a recycling partner, Central Conveyors have provided a leading supermarket with combined tipper/conveyor machinery throughout several of their depos. Designed specifically to accept an industry standard rolled cage, substantial time and cost efficiencies have been gained as a result of implimenting this system, including a time saving of 75%.

The first part of the process was to design a tipper which would lift the rolled cage into a position so that cardboard and plastic could fall freely into a receiving hopper. Previously, accessing the waste material was a laborious, time intensive manual endeavour, often leading to issues of health and safety. With the ‘lift and fall’ method the process was dramatically sped up, in the process irradicating any possibility of staff accident.

The second phase involves the transfer of the waste material along a conveyor to a skip or a bailing machine. This is where Central Conveyors experience and expertise in producing bespoke conveyors comes to bear, designed to ensure the smooth delivery of the waste quickly, efficiently and safely. A partially enclosed belt conveyor, angled to 30 degrees, transfers the waste materials up to the lip of a bailing machine or skip.

Once the cage is rolled into the tipper, the operator is able to stand well away from the machine, and via a control unitbegin the process. The operator’s health and safety is paramount. Further improvements are acheived through cost and time efficiency. Previously, the process of emptying the cage took a warehouse employee approximately six minutes on average. The implementation of the tipper conveyors now means that the job is done in just one and a half minutes, a time reduction of seventy-five percent. This time saving – and the subsequent availibility of the operator to perform additional duties – when applied to the many thousands of cages the supermarket emptys every day throughout its many depots means a huge cost and efficiency saving is acheived.

Borough Council
The first of these was for Chelmsford Borough Council, and involved a refinement to their existing waste sortation system. The requirement was relatively simple: to eliminate the need for manned tractor units to feed waste directly into the input hopper of their sortation line. The solution was a simple – but robust – chain driven conveyor terminating in a loading pit at the lower end, and the sortation line input hopper at the upper.

The pit allows tractor operators to roughly pile waste at the base of the conveyor without the need for finesse, significantly reducing the load time and improving site safety.

As the conveyor pit is exposed to the elements, we also fitted a bilge pump to prevent any build-up of water (you can just see the exist pipe coming out of the right-hand side of the pit).

The conveyor features horizontal ‘flights’ running across the width of the belt (the yellow bars in this picture) to help ensure that waste is carried up the gradient, and doesn’t ‘roll’ back down again. Notice the emergency stop button on the lower right of the picture: this is connected to a pull-cord that runs up the right-hand edge of the machine. If anyone was unfortunate enough to fall into the conveyor pit, then they could use this to stop the machine before they are carried up to the top.

Private Waste Recycling Plant
This was a slightly larger job for a private plant in Derbyshire. The requirement was for a long sortation conveyor; staff stand to the left side of this unit to remove innapropriate materials from the belt.

At the end, the materials are disgorged onto an incline chain conveyor with horizontal flights. This takes the waste materials up to the input hopper of the compressor/bailing machine.

The incline conveyor is functionaly similar to the Chelmsford conveyor featured above. It is slighly smaller, however.
