Application and working principle of screw feeder
Sep 29, 2018

The screw feeder is a new generation of products with multiple functions. Currently, it is mainly used for continuous metering and batching of powder materials in industrial production processes. The machine adopts a number of advanced technologies, reliable operation and high control precision. Especially in the continuous metering and batching of powder materials in building materials, metallurgy, electric power, chemical industry, etc., the screw feeder further reflects its superior performance.


In these different industries, the basic requirements of the screw feeder for the material to be conveyed are: the material temperature is less than 200 ° C, and it is not a metamorphic, viscous, agglomerated material. The machine measures the weight through the weighing bridge to determine the weight of the material on the tape, and the digital speed sensor installed at the tail continuously measures the running speed of the feeder.


For the requirements of quantitative feeding, the screw feeder is controlled by the output signal of the instrument to control the frequency converter to change the driving speed of the feeder, so that the material flow rate on the feeder changes, close to and remain set. The feed flow rate, in order to achieve the requirements of dosing.
