Abstract
The aim of the invention is to reduce the complexity of installing and placing into operation a device for effecting continuous gravimetric dosing and determining the mass flow rate of free-flowing products with a dosing device (4) and with the determination of the instantaneous mass flow rate before a delivery location (8) by means of a dosing controller (10), whereby the discharge is controlled by varying the rotational speed of a drive (6) of the dosing device (4) by means of a motor controller. The aim of the invention is achieved by virtue of the fact that the dosing device (10) and the motor controller (20) are combined to form a subassembly (G).
Claims10
An apparatus for effecting continuous gravimetric dosing and determining the mass flow rate of free-flowing products, the apparatus comprising:
- a feeder containing a free-flowing bulk material;
- and
- a dosing apparatus configured to control a mass flow rate of the free-flowing bulk material toward a delivery point with determination of the momentary mass flow rate before the delivery point by means of a dosing controller, with the delivery control occurring by changing the speed of a drive of the dosing apparatus by means of a motor controller, wherein the dosing controller and the motor controller are joined into a subassembly, and the subassembly is arranged within the dosing apparatus.
