What is the design basics in a press screw conveyor?

1. During transport of the material the volume inside the screw auger is decreased
2. The pitch of the screw rotor can either be decreased or you can make the screw auger conical – also a combination is possible
3. The press process is controlled by the speed of the screw rotor

The succes of the press process depends on the behaviour of the material. You must expect to adjust the process in the final application.

Which parameters can be adjusted in the final application?

1. The speed of the screw auger
2. The pressure to be put on the end plate or a similar obstruction in the outlet

How shall you control the material flow to a press screw conveyor?

1. To obtain a good stable result you must be able to control the material flow into the press screw conveyor precisely
2. A suitable method to control the material flow is by using a dosing screw conveyor

It is important that a suitable material control handling system is developed to feed the press screw conveyor. Without such a system  you will not be able to find an optimal operation for the press screw conveyor solution.

Working with press screw conveyors require process knowledge.

As a machine manufacturing company BEMA can assists in:

1. Easisly development of a revised screw auger to optimize the actual application
2. Designing and manufacturing a dosing screw conveyor system to feed the screw press
3. Designing and manufacturing mechanical components for mechanical drainage
