The type PPV conveyor is used to feed processing machines, mixers or reactors safely with free-flowing powders or granular bulk solids. Typical areas of application are in the food production sector, the plastics industry, chemicals and pharmaceuticals. It offers particular advantages when transferring small batches from a wide variety of receptacles. It allows products from sacks, barrels, bins or silos to be easily made ready for the next process.
The conveyor is distinguished by the compact configuration of vacuum generator, receiver and control unit. Another key advantage is the energy supply: no other form of energy is needed apart from compressed air. The conveyor is designed so as to be quick to dismantle, making thorough cleaning possible. Furthermore, only high-grade stainless steel is used in its construction.
Special versions for the food production or pharmaceuticals sector are also available. The filter elements can be chosen to exactly match the product that needs conveying in order to achieve maximum filtration of conveying air and separation of the product.
The controls are installed directly on the conveyor. If it is necessary to operate the conveyor from a greater distance, a remote control unit can be fitted. The controls have a built-in request indicator that automatically triggers another conveyor cycle.
Feeding a process with the conveyor is carried out in batch operations. Actuating the toggle switch at the pneumatic controls supplies the vacuum nozzle with compressed air and generates a partial vacuum in the conveyor. This causes the product to be sucked from the discharge point into the conveyor. The conveying time is set at the controls. Once this has finished, the discharging time starts, the filter is cleaned and the product discharged into the following hopper. The integrated level monitor signals when the product is needed again and starts a new conveying cycle automatically. Thanks to a vent filter at the base of the conveyor, the next hopper can be vented upon filling or discharge.
