Conveying System Efficiently Recirculating Powders, Pellets and Granulates

| Editor: Ahlam Rais

Certain situations in powders, pellet and granulate handling require raw materials to be fed back vertically into the production process. Poeth has developed its new C-Conveyor specifically for these situations: it optimises the production capacity of recirculating conveying systems and minimises the risk of contamination. The new conveyor is explosion-proof, so no costly investments in Atex protection are required. Low energy consumption is a further benefit.

The new conveyor from Poeth has been specifically designed for efficiently recirculating light powders and explosion-prone raw materials. The conveyor transports the raw materials horizontally first, and then vertically before reintroducing them to the process horizontally. The highly innovative conveyor features plastic paddles which move through a closed channel on a chain and gently ‘drop’ out of the conveying system at the release point. The design makes the conveyor ideal for products that resist emptying, states the firm.

Because the paddles seal hermetically to the conveying channel and base, product residue and product drop-back are minimised. According to the company, this makes the conveyor suitable for residue-free emptying of conveying systems without risking cross-contamination. The conveyor can run perfectly at speeds of < 1 m/s. So the conveyor is capable of conveying explosive raw materials safely and cost-efficiently without the need for costly investments in Atex protection.

In-house test unit and low energy consumption

Poeth has invested in an-house C-Conveyor test unit with a height of 9 metres. This unit is used to replicate practical situations, perform long-term ‘closed loop’ testing and subject customer products to trials in a production environment. The firm adds that this offers assurance beforehand and an opportunity to refine the results. Thanks to smart design, the conveyor combines an extensive capacity range (5 m3 to 220 m3 per hour) with low energy consumption.
