Sludge Solidification Machines

Super Precision Type Centriguge "CENTRI CLEAN"
High precision separator with strong centrifugal force
The sludge discharged during the grinding process contains moisture or oils used as a coolant, and both transport and waste disposal of this sludge are extremely difficult. A grinding sludge solidification machine efficiently compresses the sludge, thereby reducing weight and volume.
It also converts the solidified sludge into a briquette form facilitating subsequent handling.


Volume reduced from one-third to one-fifth of original sludge (weight reduced about three-fifths).

The majority grinding sludge volume consists of coolant.
The proportion accounted for by coolant is reduced to 10% or less through solidification.

Coolant recovery rate: 90% or more

Coolant discharged during solidification can be reused.

These machines can handle a wide variety of grinding sludge.

These machines include a unique compression and dehydration device that enables them to accommodate the grinding sludge produced during the machining processes for producing bearings and automotive components. (See diagram at right.)

Compression and dehydration device

A suitable speed can be chosen for when grinding sludge is compressed.
【Cost Reduction Through Grinding Sludge Solidification】
1) Reduction in waste processing costs
  Processing costs can be reduced by reducing the amount of grinding sludge produced.
  Cost reduction = discharge amount × processing fee × (approx. 50%)
2) Coolant reuse
  Coolant can be reused through a simple filtration device.
  Cost reduction = discharge amount × (approx. 50%) × (coolant cost)
3) Total cost reduction
  Total cost reduction = waste processing cost (1) × coolant cost (2)


  • Reduction the volume of grinding sludge
  • Re-use of coolant
  • Reduction the sludge decommissioning cost
