Description of operation:

The auger dosing unit type SD550 is a vertically operating dosing auger for the dosage of powders and granules (also poor-flowing ones and dust developing products, too).
The exchangeable dosing auger conveys the product through the auger tube, usually directly into a prefabricated bag.
All product-contact parts are made of stainless steel and they constitute materials which are FDA approved.
The number of auger revolutions is adjustable up to 3000 1/min.
The dosing unit is driven by means of a servo motor, whose drive shaft is directly connected by its elongation with the dosing auger.
The stirrer is driven by means of a separate three-phase motor.
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. The refill rhythm is adjustable.
