Chip and sludge treatment: Screw presses
(FSP)
In the metalworking industry, grinding sludge or other types of sludge are produced as a result of the process and must be disposed on an expensive basis. The high proportion of liquid in the grinding/sludge is problematic and thus partly responsible for the high disposal costs. Additional costs are caused by the new procurement of the disposed liquid quantity. FAUDI screw presses can significantly reduce these costs. This is done by compacting the sludge in the screw press. The volume which has to be disposed is being reduced and at the same time a large part of the liquid can be recovered and immediately returned to the production. FAUDI screw presses are an ecological and economicalsolution to significantly reduce your production waste. They can be optimally used as an economical stand-alone solution or as an upgrade to all commercially available filter systems from other manufacturers. It can be designed as a rack system or as a neck system. They can also be combined with briquetting presses only as an additional module to increase their throughput. Benefit from our screw presses in recyclables recovery, dewatering, de-oiling and many other processes.
How does a
screw press
work?
The material which has to be dehumidified will be placed into the hopper. The rotational movement of the screw conveys the material into the dehumidification area. The dehumidification section consists of a slotted sieve cylinder, whose outlet opening is closed by a spring-loaded pressure plate. The permanent supply of material causes compaction of the material in the dehumidification area and the liquid will be squeezed out. This liquid can drain through the drain hole and be reused. Due to the increasing pressure in the dehumidification area, the pressure plate is displaced, the dehumidified material falls into the container, and then the pressure springs press the pressure plate back against the dehumidification area and close the outlet opening. Optionally, the dehumidification screw can be equipped with a return pump station.
