Using a Gravimetric Feeder for Dosing Pharmaceutical Bulk

The optimal feeder depends on the powder's flow characteristics, as well as the precision and throughput needed. In the pharmaceutical industry, single or twin-screw, volumetric or gravimetric feeders are commonly used to meter powders in various processes, such as milling, granulation, coating, direct compression, and blending.

Journal of Engineering and Technology Research

More recently, Roberts and Manjunath (1994) analyzed the mechanics of screw feeder performance in relation to the bulk solid draw-down characteristics in the feed hopper. In their study, the force exerted on the screw flights is assumed to be uniformly distributed along the whole feed length and three empirical pressure ratios are used in the determination of the required torque.

Screw press

The Screw Press is built for dewatering of pulp suspensions from inlet consistencies of 3-12% to outlet consistencies up to 30% and even higher. Excellent washing efficiencies in the sense of removing COD and ionic trash can be achieved, thus the machine is found in pulp and recycled fiber applications. Get price

Vibrating Feeder

Vibratory feeders are used in gravimetric feeding systems to handle solids with particles that are loo large to be handled by screw, rotary-vane, or vertical-gate feeders, or in operations where the physical characteristics of the solid particles would be adversely affected by passage through these volumetric feeding devices. The discharge flow pattern of a vibrating feeder is extremely smooth Get price
