Two types are available:
  • Closed pipe-type feed screw
  • U-type trough feed screw

The U-type trough feed screw is open at the top. It comes in two variants: with or without a cover. The U-type trough feed screws also include discharge baskets fitted with an extended charge and a screw in the bottom section. The U-type trough feed screws can be fitted with a heating or cooling jacket.

Feed screw can be installed on a support structure permanently attached to the ground or be equipped with casters for transport. The class of the material the machine is made of depends on its intended purpose. For the food industry, the machine is made of acid- proof material and plastic materials approved for contact with food. Non-alloy steel elements are covered with an anti-corrosive coat.


The closed pipe-type feed screw is a pipe with a shaft inside with welded screw blades and passive bearing. The screw’s blades have different pitch, depending on the type of the transported raw material and the planned capacity. This type of conveyor is closed, which means that the screw cannot be accessed directly. Thanks to the closed structure, the transported raw material does not spill outside the machine during transport. The machine can be equipped with a pull screw. In this version, the drive unit is located on the raw material feeding. Some feed screwsare equipped with push screws with gear motor installed on the feeding side. The feed screw is fitted with an initial or end bearing. Depending on the type of transported raw material, slide or bearing rests are installed. When required by the customer, the screw feed can be fitted with a washing system in the spindle. This enables washing the feed from the inside, eliminating the need to dismantle it.
