Mahr’s AS25, AT16 feeders are specifically designed to feed free flowing products as well as poor flowing powder satvery low rates. There movable feed hopper makes it ideal for applications that require quick material changes. To make a material change, just remove the existing hopper and replace it with a new clean hopper.

Call for Information
Description
The removable feed hopper can also be used as a storage container, completely eliminating cleaning and the possibility of product contamination. These include a single screw hopper to feed free-flowing products, twin screw with horizontal agitator to feed the most difficult products. The feeder can be easily integrated with gravimetric or volumetric controls, as well as installed separately or in a production line with multiple feeding devices.

Application
The use of the different load cells and control versions are described on separate technical data sheets.
The AS25-AT16 each have a larger throughput range, measured on free flowing granules with a bulk density of 0.6kg/l 37 lb/cuft. The throughput data indicates values subject to individualtesting. Mahr offers additional twin spiral screws based upon results of material testing.
