A rotary crushing apparatus includes a container (including a stationary drum, a rotating drum, and a top plate) into which a processing object containing raw material soil is fed. A rotating shaft extends in the vertical direction, and an impact member rotates in the rotating drum by the rotation of the rotating shaft to crush the processing object. Then, the rotating shaft is provided in such a way as to penetrate the top plate 10a, and the rotating shaft is rotatably held via ball bearings provided in the vicinity of the top plate. In addition, the lower end of the rotating shaft is a free end.

Disclosed is a bladed grinder (20) for plaster waste, comprising a frame (10) comprising a support for a rotating shaft, comprising a main rotating shaft (30) comprising a plurality of vanes (40) radially attached on the main rotating shaft (30), comprising a system for rotating the main rotating shaft (30), comprising at least one inlet opening (60) for introducing waste comprising plaster, comprising at least one outlet opening for recovering large size waste, comprising, in the lower portion, openings covered with separation grids for filtering the defragmented gypsum, comprising a partially cylindrical cover which covers a continuous surface, characterised in that the cover is divided into at least two removable cover sections (50).

A shell liner for a stirred grinding mill is configured to be releasably fitted to the inside of a shell of the mill within a grinding chamber thereof. At least a part of a surface of the shell liner that is configured to be exposed within the grinding chamber constitutes a wear surface. The shell liner includes at least one polymer-ceramics panel having an elastic material layer and wear resistant inserts retained by the elastic material layer. Exposed surfaces of the wear resistant inserts form part of the wear surface of the shell liner.

A rotary impact separator is provided for separating a material. The rotary impact separator includes a body portion comprising one or more walls. The one or more walls define a substantially hollow chamber, an inlet opening, a first outlet opening, and a second outlet opening. The rotary impact separator includes an impact device extending at least partially into the hollow chamber. The impact device includes a shaft that extends within the hollow chamber. The shaft rotates within the hollow chamber. One or more blades are attached to the shaft and contact the material. A diverter is attached to an interior surface of one of the one or more walls. The diverter extends along the shaft and projects from the interior surface toward the shaft. Methods for recovering two or more co-products from a material are provided.

There is provided an apparatus and method for comminuting a material. The apparatus may comprise a chamber and an inner surface with a plurality of protrusions, and a hammer positioned within said chamber comprising an outer surface having a plurality of second protrusions configured to engage with the first protrusions. The outer and inner surfaces may be separated by a gap distance which defines a comminution zone. The anvil may be rotated to cause a material to be comminuted as the material passes through the comminution zone.
