WAM Dry-Batch Concrete Plant Collector

Drybatch Dust Collectors are designed for dust collection from the truck mixer inlet zone in dry batch plants during loading of the truck mixer. They are equipped with horizontally mounted filter elements, a compressed air jet cleaning system integrated into the access door and a suction fan.

Dry-Batch Concrete Plant Collector
  • Low dust emission
  • Unrivalled user-friendly and maintenance-friendly design
  • Compact design

The DRYBATCH Dust Collector separates dust from the air flow by means of horizontally mounted pocket-type filter elements. Dust drops down after a programmable, automatic compressed air pulse-jet cleaning device integrated into the access door has removed it from the filter elements.

The dirty air flow may enter the filter casing from the top inlet flange where heavier particles are subsequently pre-separated while the dust flow is on the descent. Alternatively, dirty air may enter through the bottom flange that can be fixed on a PT-type WAM hopper, which is equipped with a special diffuser for pre-separation of heavier dust particles.
DRYBATCH Dust Collectors are designed for suction application.
