Grindforce. GrindForce is the trade name for Outotec's new profiled grinding rotor for use in stirred milling, taking its name from the very successful FloatForce® technology, which like GrindForce, is a new-generation mixing mechanism. The key to the new HIGmill design is the agitator (grinding rotors) and grinding chamber stator rings ...
An attrition mill comprising a grinding chamber (1), an axial impeller (10), a chamber inlet (3) for admitting coarse particles and a separator comprising a chamber outlet (6) through which fine particles exit from the chamber. The mill is characterized in that a classification as between coarse and fine particles is performed in the mill upstream of the separator.
4x3-15 Disk Attrition Mill Disk Attrition Mills are used in a host of applications involving the grinding of solids contained in a liquid slurry. The machines can be configured with four stator/rotor combinations to match individual process requirements.
Transport of slurry through the mill is described by a function which relates the hold-up of slurry, grate design, grate open area and mill speed to the volumetric discharge rate through the grate (Morrell and Stephenson, 1996): Jp = k Q0.5 g-1.25 A-0.5 f0.67 D-0.25 (7) where. Jp = fractional slurry hold-up. D = mill diameter (m)

Attrition mills are more appropriate for "mid-range" size particles. Such mills utilize 3–10-mm media to produce material ranging in size from approximately 1 to 10 microns. The first "small media" mill was introduced about 60 years ago. It was named a "sand mill" because it used 1/64–1/8 in. Ottawa silica from Canada.

Sludge is a residual, semi-solid by-product left from industrial or refining processes. It is a separated solid suspended in a liquid, typically containing major quantities of interstitial water between its solid particles. This material can be dried to cut its volume and reduce most of the moisture content of the biosolids present in the sludge.
