Single Screw Compact Volumetric Feeder

Every Feeder initially is a Volumetric Feeder. In principal, volumetric feeding is the simplest & most economical feeding solution available for feeding bulk material. Bulk material is held in feeder hopper and constantly fed into a process per unit of time by varying screw speed. A controlled feed rate may be achieved through a calibration process where a timed sample is taken and weighted and screw speed adjusted accordingly. Although there is no weight feedback to assure feeding accuracy over time, this may not be a concern for material with consistent bulk density application.
# This feeder is suitable for volumetric feeding of very easily flowing powder and granules
# The feeding hopper is specially designed for quick changes of bulk material with no clean up time. Special feeding screws ensure exact discharge of products of various characteristics

Operation:
The product is fed into a feeder hopper from overhead silos or any discharging device. In feeder hopper the bulk material is fed uniformly to the feeding screw flights by pneumatic vibrating device (optional) to avoid bridging of the material in the feed hopper. The speed of feed screw, to achieve desired federate, can be varied continuously by motor control panel supplied with the feeder. This combination ensures reproducibility.

Application:
Feeder can be use in chemical, pharmaceutical, food, plastic and similar industries where controlled feeding of bulk material is required.
