The auger dosing unit type SD-330 is a vertically operating dosing auger for the dosage of powders and granules (also poor-flowing ones and dust developing products, too).
The dosing unit is driven by an electrical motor, of which the motor shaft is directly connected by its elongation with the dosing auger.
By means of a step-down gear, the main shaft drives as well a stirrer, thus ensuring the steady filling of the dosing auger.
The variable number of revolutions of the drive as well as the starting and stopping procedures of the machine are regulated by a speed controlling device.
The dosing quantity results from: “flight volume” multiplied by the number of auger rotations per dosing operation.

The auger rotations are freely adjustable.

The dosing unit is equipped with a “horizontal infeed auger”, which conveys the product from a product supply or from a storage container into the dosing hopper and which, therefore, decouples the filling of product fluctuations in the storage area. By means of a product level controller, the filling level in the dosing hopper is kept constant.
