The crushing section is located at the lower portion of the device, and is internally provided with stirring rods and crushing balls, and a grading discharge module is provided at the bottom of the crushing section. A grading discharge module is used in the device and a continuous wet ball-milling separation method applying the device. The device implements continuous operations of material crushing and grading by means of the material distributor, wet shearing, wet crushing, and wet grading.

A stirred ball mill including a grinding container, in which an agitator shaft having grinding elements is arranged, whereby a grinding chamber is formed between the grinding container and the agitator shaft, into which chamber the grinding elements extend and into which at least one inlet duct for grinding material opens and in which a dynamic separation device for grinding bodies is provided, the separation device having recesses for feeding back the grinding bodies, and in which the agitator shaft has at least one recess, which widens the separation device and extends in the axial direction into the grinding chamber for improved distribution of the grinding bodies in the grinding chamber.

An agitator ball mill includes a grinding chamber, a rotatably mounted agitator shaft, which protrudes into the grinding chamber and on which agitator elements, in the form of paddle wheels, are arranged spaced apart from one another axially, and an inlet for supplying material to be ground and grinding bodies and an outlet for removal of the ground material. The agitator elements 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. In the grinding chamber there are arranged return conveyor elements which are joined to the agitator shaft for conjoint rotation therewith and which convey the mixture laterally alongside and/or between the agitator elements inwards towards the agitator shaft.

A separating device for a ball mill or an agitator ball mill as well as a ball mill or agitator ball mill with a separating device, wherein the ball mill or agitator ball mill includes a cylindrical grinding container with a first end opening and a second end opening, wherein the first and second end openings can be closed by a first and a second closure device, wherein a ground stock inlet is arranged in the region of the second end opening and a ground stock outlet is arranged in the region of the first end opening and wherein the separating device is assigned to the ground stock outlet. The separating device includes a plurality of first and second screen segments with screen apertures, which are arranged in an alternating manner on a frame.

An apparatus and continuous process for making milled solid in liquid dispersions comprises several steps: 1) Forming a pre-mill mixture of pre-mix, milling media, and previously milled dispersion. 2) Milling the pre-mill mixture to form a milled mixture of milling media and milled dispersion. 3) Separating a portion of the milled dispersion, which is substantially free of milling media, from the milled mixture. 4) Recycling the un-separated mixture by adding additional pre-mix to form the pre-mill mixture to create a continuous milling process. The pre-mix comprises a liquid and a solid. The process is a continuous process and the milling media is recycled through the milling step. Much of the milled dispersion is also cycled through the milling step several times and only a portion of the milled dispersion, which is substantially free of milling media, is removed as the milled dispersion product.

A system for screening deburring media during deburring operations of a hardware part comprises a deburring machine comprising a media slurry basin, a deburring media slurry disposed in the media slurry basin, and a media screening device freely movable within the deburring media slurry to define a dynamic zone of capture to capture noncompliant media. The media screening device can comprise a housing defining an inner chamber, and can comprise a plurality of openings each sized to restrict compliant deburring media from passing through the opening, and each opening sized to permit passage of noncompliant deburring media into the inner chamber. Each opening can comprise a counterbore. The media screening device can comprises at least one removable housing body removably coupled to the housing to facilitate removal of captured noncompliant deburring media. A method is disclosed for screening deburring media during deburring of a hardware part.

Agitator mill including a grinding chamber containing grinding bodies and an agitator shaft, which revolves therein about a horizontal agitator shaft axis, which supports several grinding members, which are connected to it in a rotationally fixed manner and which are spaced apart from one another in the direction of the horizontal axis, preferably in the shape of grinding disks, which move the grinding bodies, whereby, on the outlet side, the agitator shaft has a basket, which is preferably studded with grinding members on its outer circumference and which overlaps the split tube-supporting outlet, characterized in that in the region of its free end, the basket has a section with an enlarged outer diameter.

An agitator mill including a grinding chamber containing grinding bodies and an agitator shaft, which revolves therein about a horizontal agitator shaft axis, which supports several grinding members, which are connected to it in a rotationally fixed manner and which are spaced apart from one another in the direction of the horizontal axis, preferably in the shape of grinding disks, which move the grinding bodies, whereby, on the outlet side, the agitator shaft has a basket, which is preferably studded with grinding members on its outer circumference and which overlaps the split tube-supporting outlet, whereby a separation chamber is formed between the inner surface of the basket and the split tube-supporting outlet, whereby the basket has slits for returning grinding bodies from the separation chamber into the grinding chamber, which slits lead into the free front surface of the basket, which faces away from the grinding chamber.

A grinding media handling system for a vertical grinding mill comprises: a reservoir; a pump, such as a sump pump or a horizontal pump, for pumping water and/or a slurry of material to be ground from the reservoir via an inlet in an upper section of the vertical grinding mill into a grinding chamber of the mill; means for adding grinding media to the water and/or slurry upstream and/or downstream of the pump; and means for discharging slurry and grinding media from a lower section of the vertical mill.

An agitator mill including a milling chamber and a milling rotor, which forms a circumferential boundary wall of the milling chamber during operation. The milling elements are made to execute a milling movement in the milling chamber by the milling rotor. There is also a slit tube for removing the milled material while separating out the milling elements.
