Single Screw Extruder is what  ?
The basic structure of single screw[http://www.extruderschina.com/<b>Plastics Extruder</b>] extruder mainly consists of the transmission
system, feeding system, extruding system, heating[http://www.extruderschina.com/ <b>Twin Screw Extruder Supplier</b>] system, and cooling
system, as well as nose and mouth molds. 
Transmission System
The transmission system, whose purpose is to achieve the required[http://www.extruderschina.com/<b>Steel Pipes Coating</b>] torque and uniform RPM of the screw, is an important part for extruder to complete the extrusion process under specific conditions (such as die head pressure, screw rotation, extrusion, temperature, etc). The transmission system is composed of motor, reducing unit transmission and bearing system. Feeding System
The feeding system of single screw extruder is composed of hopper and feeding devices. The shape of feed hopper can be conical, cylindrical or rectangular etc. On one side of hopper [http://www.extruderschina.com/<b>Coating Plant For Steel Pipe</b>]there is a hole used formaterial observation, and at the bottom there is an opening and closing door used for feeding control. The hopper cover can be closed keeping dust, moisture and other contaminants outside. The material of hopper is normally aluminum and stainless steel plate. And the volume of hopper should contain the extrusion capacity at least 1- 1. 5 hours. The shape of feeding port can be either an rectangle, which is the preference, or a circle. The feeding way can be manual or automatic. Automatic feeding device mainly consists of blast-furnace burden, spring feeding, vacuum suction and so on.
