Screw Feeder in GMP and Industrial Design
The JEHMLICH Screw Feeders in three 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 63 GMP
The Screw Feeder SD 63 is made from stainless steel AISI 316 with FDA-compliant seals. With its GMP design and polished surfaces it is used for applications in pharmaceutical and food industry.
The conveying screw and the agitator tool can be disassembled for quick cleaning by loosen a clamping ring.
For volumetric and gravimetric dosing
GMP conform
Material in contact with product: AISI 316 / 1.4404
FDA-compliant sealings
Geared motors for the required ATEX zone
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
