Screw press machines are an essential piece of equipment for waste management operations. They help separate liquid from solid waste and reduce the volume of waste. This helps make waste handling and disposal more efficient.

Screw press machines work by compressing the waste between a worm shaft (the screw) and the cylindrical enclosure as the worm screw rotates. The liquid in the waste is squeezed out through perforations in the cylindrical chamber. The remaining solids are then discharged.

Screw press machines are commonly used in food processing, chemical, pharmaceutical and municipal waste operations. They are ideal for applications that require continuous dewatering of solid waste with high liquid content. Some types of material screw presses handle include:

  • food waste
  • dewatering sludge
  • organic waste
  • pet waste
  • chemical sludge
  • biosolids
  • agricultural waste

Multi Disk Screw Presses – Manufacturer Tell How They Work

Multi disk screw presses use multiple fixed compression disks spaced along the length of the rotating screw shaft to compress and squeeze liquid from the waste. These types of screw press machines offer a few benefits:

  • Higher compression – The multiple fixed disks generate higher compression forces compared to single shaft style presses. This results in higher dewatered solids content and lower liquid content in the discharged waste.
  • Gentler compression – Though the compression is higher, multi disk presses provide a gentler and more gradual compression compared to single shaft presses. This helps protect heat-sensitive materials from damage.
  • Less shaft wear – The fixed disks bear most of the load, reducing wear on the rotating shaft. This leads to longer lasting screw press machines.
  • More versatile – Multi disk presses can handle a wider variety of waste types, including the more abrasive or stringy types of waste that single shaft presses struggle with.

A Multi Disk Screw Press Machine Consists Of These Main Parts:

•The cylindrical compression chamber – This houses the rotating screw shaft and fixed compression disks. The chamber has perforated sides to allow squeezed out liquid to escape.

  • The rotating screw shaft – This rotates inside the compression chamber and helps transport the waste material forward.
  • The series of fixed compression disks – These discs are spaced along the screw shaft and remain stationary while the shaft rotates. They provide the primary compression force to squeeze liquid from the waste.
  • Feed hopper – This funnel-shaped hopper at the top allows waste to be fed into the machine.
  • Discharge chute – Located at the end of the compression chamber, this chute ejects the dewatered solid waste after liquid has been squeezed out.
  • Drive system – This powers the rotation of the screw shaft, usually an electric motor and gearbox assembly.

Multi disk screw press by Multi disk screw press manufacturer, are well suited for applications that require high compression force yet gentle handling of the waste material, like processing of organic or food waste streams. The segmented design offers benefits of lower operating costs due to longer component life spans.
