An agitator ball mill comprises a grinding chamber (1), a rotatably mounted agitator shaft (5), which protrudes into the grinding chamber (1) and on which agitator elements (10, 20, 30), in the form of paddle wheels, are arranged spaced apart from one another axially, and an inlet (6) for supplying material to be ground and grinding bodies and an outlet (7) for removal of the ground material. The agitator elements (10, 20, 30) are constructed in such a way that, during operation, they convey a mixture consisting of material to be ground or dispersed and grinding bodies through their interior outwards away from the agitator shaft (5). In the grinding chamber (1) there are arranged return conveyor elements (17, 27, 37; 47; 57) which are joined to the agitator shaft (5) for conjoint rotation therewith and which convey the mixture laterally alongside and/or between the agitator elements (10, 20, 30) inwards towards the agitator shaft (5).

An attritor mill may include: a grinding container, including a grinding chamber and a rotor within the grinding container. The grinding chamber may be delimited by one or more side walls and a bottom wall. The rotor may include arms extending radially relative to the rotation axis of the rotor. The arms may include first and second arms on one or more levels with reference to a distance from the bottom wall. During normal operation of the attritor mill, a first arm closer to the bottom wall may be radially shorter than a second arm above the first arm. The attritor mill may be configured to treat material by: mixing the material with grinding free bodies in the grinding chamber; and agitating the material and the grinding free bodies by causing the rotor to rotate, so that the first and second arms strike the grinding free bodies.

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 device that effectively produce matcha powder is provided and includes: a stirred media mill grinding portion, having a grinding chamber inside, wherein a side of the stirred media mill grinding portion defines an outlet port; a pin bar, rotatably received in the grinding chamber, wherein an outer circumference of the pin bar defines an opening, communicated with the grinding chamber; an air classifier, connected to the outlet port through a first tube assembly and defining a first output port and a second output port; a storage portion, connected to the first output port; a collector portion, connected to the second output port through a second tube assembly; and a wind guider, wherein an air outlet of the wind guider is connected to the outlet port and an interior of the storage portion to create a negative pressure environment.

A horizontal bead mill for dispersing secondary battery materials and a method for dispersing conductive materials using the horizontal bead mill for dispersing the secondary battery materials are provided. The horizontal bead mill includes a vessel including an inlet and an outlet configured to receive disperse media. The vessel is filled with beads. A rotor is rotated in the vessel to rotate the beads to disperse the disperse media. A driving unit rotates the rotor. An inner surface of a sidewall of the vessel is inclined at a predetermined angle for an axis of the rotor in a manner that an inner diameter of the vessel gradually decreases from an inlet side to an outlet side.

A mineral liberation machine comprising vertical wet grinding mill (10) for grinding coarse material comprising a cylindrical housing (14) containing a rotatable shaft (15) creating an annular channel (17) with an input feed (16) for supplying coarse material and an output feed (18) for withdrawing ground product, in which the rotatable shaft (15) is equipped with a plurality of rotor discs (20) and the cylindrical housing (14) is equipped with one or more stators or stator discs (22), the discs (20, 22) on the rotatable shaft (15) and cylindrical housing (14) are interleaved such that the ratio of the height of the housing (14) to the diameter of the housing (14) is low with the diameter to height ratio being between 0.6-1.2.

A screw flight system including a helical screw flight, and at least one wear lining element is disclosed. The screw flight system further includes a guiding system including at least one guide pin configured to be arranged on one of the helical screw flight and the at least one wear lining element, and at least one guide hole arranged on the other of the helical screw flight and the at least one wear lining element, wherein the at least one guide hole being configured to receive the at least one guide pin. A vertical grinding mill including the screw flight system, a replacement kit of wear lining elements, and a method for mounting thereof are also disclosed.

A device for mechanical activation of organic and/or inorganic substances and/or substance mixtures in chemical, pharmaceutical, food-related and/or building material-related applications includes a disk-like agitating body for rotationally fixed mounting on an agitator shaft, and at least one impact unit, which has a head region with an activation surface for cooperation with activation bodies, wherein the at least one impact unit is fastened to the disk-like agitating body radially on the outside with respect to an axis of rotation of the disk-like agitating body. An agitator system with the device is also disclosed.

A system for a vertical grinding mill. The system includes a longitudinally extending shaft supporting a helical screw flight and at least one adaptor plate configured to be fixedly mounted to the shaft. Each adaptor plate includes at least one first locking member. The system further includes at least one wear segment configured to be supported by the at least one first locking member. Further, a replacement kit, a kit of wear protection elements and a vertical grinding mill is provided.

An agitator mill, in particular in the form of a full-volume disk mill, with a grinding container, an agitator shaft circulating therein about a horizontal axis, which carries several grinding disks, which are connected thereto in a rotationally fixed manner and which are spaced apart from one another in the direction of the horizontal axis, wherein the grinding disks each have slots or apertures, wherein the agitator mill has drivers in the region between two grinding disks, which drivers circulate synchronously with the grinding disks during grinding and which provide a movement component in the radially outwards direction to at least a portion of the grinding bodies, which come into contact with them, in that they displace these grinding bodies directly in response to the circulation thereof, preferably in the radial direction.
