LACKEBY SCREW CONVEYOR PRESS SCP
Lackeby Screw conveyor press is developed and dimensioned for heavy duty and efficient dewatering
Function
The company’s screw presses are based on a shaftless screw conveyor, which transports the material into the press unit. Material is dewatered in the unit’s perforated dewatering zone. A plug of dewatered material is formed at the outlet end due to the resistance created by the distance between the end of the spiral and the weight-loaded outlet shutter.
The shaftless spiral makes the screw press particularly suitable for materials that tend to stick to, and tangle with, a shaft. Materials with variable particle sizes and irregular shapes can also be transported without problem using shaftless screw conveyors. Shaftless spirals reduce maintenance needs, as they can work filled to a far greater degree in the conveyor.
Design
The press unit is equipped with an inspection hatch to make maintenance simpler and enable flushing of the press pipe. Flexible attachment of the presspipe in the press unit makes presspipe replacement easier. The spiral is fitted with a brush at the drainage to minimize the risk of clogging. As standard, screw presses are made in stainless steel or acid-proof steel with Hardox wear bars. Spirals are made of black material as standard, but are also avaliable in stainless steel.
