Mô tả

H-MSP-203 Multi Plate Screw Press is a sludge dewatering machine of solid-liquid separator, which Screw Press Type can realize the Sludge dewatering or Sludge Dehydrator effect.

H-MSP-203 Multi Plate Screw Press developed by HITACHI utilizes the dewatering principles of force-water homo-direction,thin-layer dewatering, proper pressure, and extension of the sludge dewatering path.

The new equipment, more advanced than the traditional dewatering equipment which is easily blocked, unsuitable for low-concentrated sludge and oily sludge, of high consumption and difficult to operate, well eliminate these problems and are of higher efficiency and power saving.

Multi-plate screw press, which is controlled by the electric control cabinet, allows automatic continuous operation of sludge flocculation, thickening, dewatering, and filtrate discharging.

Products Details Multi Plate Screw press H-MSP-203

It has solved several technical problems of other similar sludge dewatering equipment including belt presses, centrifuge machines, and plate-and-frame filter press, which are frequent clogging, low concentration sludge/oil sludge treatment failure, high energy consumption, and complicated operation etc.

Factors including concurrent water-power, thin lay…

Factors including concurrent water power, thin-layer dewatering, proper pressure and dewatering path extension etc. were applied by the dewatering mechanism of HItachi multi-plate screw press. Lower energy/water consumption and longer service life can realized without changing the properties of the feed materials and with high efficiency.


Hitachi, as the industry leader and first brand of Multi-plate Screw Press, have the strongest R&D capability, most application cases, largest production capacity, richest product lines, and highest recognition from professional users.

Hitachi built the finite element model according to ANSYS screw shaft pressing theory, which basically solved the problems of product design, technical innovation, and equipment operation. On the basis of the advanced model,

Hitachi successfully developed the following significant technology innovations:

  • 400 Series Screw Shaft (Industry First)
  • Wear-free type of Multi-plate Screw Press (Industry First)
  • Special screw shaft for Sludge Thickener (Industry Only)
  • Special screw shaft and machine for inorganic material (Industry Only)
  • Special screw shaft and machine for petrochemical, pectin, paper industry (Industry Only)


For its special structure, accurate design, and processing, Hitachi Multi-plate Screw Press is characterized by
the following features:

-The exclusive pre-thickening device enables a wide solid concentration ranging from 3000mg/l to 50000mg/l

The thickening zone and the dewatering zone make the machine applicable to both highly concentrated sludge and that with high water content. It’s able to directly treat sludge with a solid content from 3000mg/l to 50000mg/l.

The exclusive pre-thickening device enables excellent performance while dewatering sludge with high water content

  • The problems of gravitational thickening disappear and highly efficient thickening is achieved.
  • Flocculating and thickening in the same time reduce the subsequent dewatering pressure.
  • Adjusting the expansion valve to make the sludge be the best state for dewatering.

-Fixed and moving plates replace filter cloth, self-cleaning, clog-free, easy to handle oily sludge

The traditional dewatering equipment is easily got blocked while the multi-plate screw press allows continuous operation with no blocking due to that the moving of the fixed rings and moving ring clean itself. Therefore, it’s especially good at oily sludge with excellent performance. Moreover, it doesn’t need additional water for high-pressure clean-
ing so that no smell or secondary pollution will be produced.
