BDG Undulate Roller Feeder

The BDG roller feeder is a combined machine, which has dual function: feeding and sieving. It is designed specially to feed the heavy crushers continuously. Owing to the front-sieving, this equipment can sieve out the desirable, fine materials, which improve the production capacity of the whole crushing system and reduce the attrition to crushers. Usually, the fine materials contain mud, and the mud may jam the crusher. So it can avoid the jam by sieving out the fine materials in advance. This machine has many rollers, it runs in the same direction, make the stone from one border. The gap between adjacent roll forming can make crushed material leakage. BDG roller feeder divided into steel hopper, feeding section and sieve section.
