Screw Feeder in GMP and Industrial Design

The JEHMLICH Screw Feeders in 2 sizes are used for volumetric dosing of bulk solids in a broad range of material processing. The screw conveyors’ properties are laid-out to the specific material characteristics. The build-in agitator avoids reliably clumping and bridging above the screw conveyor.

A gravimetric dosing with load cells is available as an option.

Screw Feeder SD 160 Industrial

The Screw Feeder SD 160 with its large buffer volume is optimized for usage as receiver tank or intermediate storage in bulk solids processing. With modular attachments the feeding of the screw feeder can be done from big bags, pneumatic conveying systems or on-site conveying units.

The dosing into the following process can be done either volumetric or gravimetric. With decoupling, e.g. rotary valve, the screw feeder can discharge into a pneumatic conveying system. An optional twin screw type is used in case of two separate discharge points.

Shaft sealing with packing glands secure a reliable operation while conveying abrasive materials.

  • For volumetric and gravimetric dosing

  • Material in contact with product: mild steel or stainless steel

  • Shaft sealings with packing glands

  • Level monitoring via switch or weighing system

  • Motion sensor for screw conveyor and agitator

  • Geared motors for the required ATEX zone

  • Optional: twin screw type for two separate discharges
