ZK ING - Screw Conveyors
Screw conveyors are used for transporting and dosing dry bulk materials. The basis is a pipe or trough, inside which a conveyor spiral rotates on a shaft. They are designed with regard to model standards based on the specific performance and length requirements of the client. The material design depends on the type of transported material and its properties. In the case of longer lengths and the transport of non-abrasive material, the screw shafts are supported in the middle area by an intermediate bearing. The conveyor drive consists of a three-phase asynchronous motor with a gearbox. The conveying performance can be regulated by changing the motor speed via a frequency converter. To control the operation and speed, the conveyors can be equipped with a rotary motion sensor. To close the conveyor, a closing device can be installed at the inlet and outlet of the conveyor.

Micro-dispensers
These are special screw conveyors designed for the dosing of small quantities of mostly special bulk materials. The base is a tube, inside which a separate screw spiral or spiral welded on the shaft provides bulk material transport. In order to evenly feed the feed into the conveyor, the micro-dispenser is equipped with a smaller mixing device located in the inlet shaft. These devices can have their own independent drive, or they can use the drive of the dosing spiral. Material design depends on the type of transported material and its properties. The dosing power can be controlled by changing the motor speed via the frequency converter.
