Stainless Steel Screw conveyors are with frequency speed

- Mar 18, 2019-

The following screw conveyors are used to transport PVA granules and PVA powders. Inside of screw conveyor is polished by 200 grade,outside is acid clean.

Usually there need a small control box to control the start and stop of screw conveyor during running. With the help of control box,screw conveyor can work stably and avoid any current overload. Sometimes,customer need adjust the speed of conveyor as per actual conveying request,then we designed the frequency motor on such conveyors. The frequency motor is working with frequency inverter.

Let’s take an example of frequency screw conveyors’ technical data as following form :
