    摘要: A silicon extrusion plant has a silicon extruder and a silicon feed device configured to load the silicon extruder. The silicon feed device has a feed hopper. The feed hopper opens into a feed opening arranged at the bottom thereof. The feed opening is in a fluidic connection, via a feed duct, with an inlet zone of the silicon extruder. A feed screw arranged in the feed hopper in such a way as to be drivable for rotation protrudes into the feed opening at least partly. The feed screw has a cone portion and a cylinder portion. According to another aspect, the silicon extrusion plant has at least one feed pressure sensor configured to measure an actual feed pressure of silicon material to be extruded. The pressure sensor is arranged in a transition region between the silicon feed device and the silicon extruder. A control unit is in a signal communication with the feed pressure sensor and a feed drive device in order to drive the silicon feed device. The control unit is used to define a nominal feed pressure and to transmit an actuating signal to the feed drive device depending on a difference detected between the nominal feed pressure and the actual feed pressure. As a result, a silicon extruder is obtained that is usable for the mass production of silicon extrudate.

    摘要: A filter mesh assembly configured to control particulate material in a filter assembly of a plastic extruder. The filter mesh assembly includes a wire mesh filter having a square weave construction defining a predetermined pore size with the wire mesh filter having flattened surfaces of adjacent wires on the same plane and configured to allow a portion of the scraper to move across the wire mesh filter assembly. The assembly also includes a wire mesh supporter having a square weave construction and a characteristic of sufficient strength to support the wire mesh filter against a breaker plate. The wire mesh filter and the wire mesh supporter are diffusion bonded to each other as a unified structure and disposed in a housing between an inlet and breaker plate. The configuration allows passage of molten plastic through the breaker plate and lateral movement of material, parallel to the breaker plate.
