Lackeby Screw conveyor press is developed and dimensioned for heavy duty and efficient dewatering
The design is based on long experience and both minimises and simplifies maintenance work.
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.
