SPL Micro-Feed Screws

Supplier: Inquip

SPL and SPS-type Micro-Feed Screws are auxiliary screws combined with a larger main screw feeder.

Before reaching the set feed rate the main screw feeder is stopped by a proximity switch to allow the Micro-Feed Screw, which is flanged beneath an opening in the pre-outlet section of the main screw feeder pipe, to feed the missing quantity of material with high accuracy through the outlet of the main screw feeder into the weigh hopper.
