A screw feeder, screw feeder (aka screw feeder, automatic screw feeding machine) Scope and operating characteristics: the screw feeder can be used in pelletizing, plastic, plastic, pharmaceutical, food, chemical production conveying the material in the process of powder pellets. Storage bins and conveyor tubes are made of stainless steel (material according to customer requirements) production, to ensure that the raw materials during transport completely free from contamination. The system has a time relay, according to the quantity for each set on the quantity of time TZ series screw drive feeder for plastic processing machinery ancillary equipment required can be powdered or granulated plastic materials automatic transmission into the hopper, or high-speed mixers, blenders and other containers, in contact with raw parts are made of stainless steel raw materials during transport is completely free from contamination, do not bring any foreign matter. Second, the screw feeder (aka screw feed machines, automatic screw feeding machine) Features: 1, easy to install, and can be moved, such as multiple mixer using the same material, just a platform feeder simultaneously on multiple Banliao for feed, eliminating the trouble of artificial feeding so that the work becomes safe feeding, more time and more effort. 2, advanced design reasonable, easy operation and maintenance, compared with the vacuum feeding machine, eliminating the need for frequent cleaning of the filter can be trouble. 3, can be customized stand-alone material on this series of models up to 2-6 meters in height according to customer requirements, and multi-machine tandem, pumping the feed rate of 1-3 tonnes / hour. Includes: automatic control feeding, easy maintenance, safety and reliability, improve work efficiency, etc.
