A pill grinder and a method for using thereof are provided. The pill grinder includes: a base plate; a guiding assembly; a handle component including a pair of handle connecting rods, wherein, a first connecting rod is connected to a first end of each handle connecting rod, a roller shaft is connected between the handle connecting rods, axial directions of the roller shaft and the first connecting rod are both parallel to a first direction, the first connecting rod is kept pressed towards the base plate by an elastic returning component; and a grinding component, sleeved outside the roller shaft. When the handle component rotates around the first connecting rod, guided by the guiding assembly, the grinding component has a grinding stroke along a second direction perpendicular to the first direction. Therefore, pills can be better grinded with easier operation and less time, and safety in use is largely enhanced.

The present invention relates to an anti-adhesion crushing tool for crushing damp ores. The anti-adhesion crushing tool can effectively improve the current working environment in attapulgite crushing, and is beneficial to effectively improve the anti-adhesion properties of the attapulgite clay.

An in-feed roller for a wood chipper and a process of making thereof. The roller has seven, eight, or nine perimetric planar sides. It is made by providing a plurality of curved plates equal to the number of sides and a pair of end plates having a plurality of perimetric edges equal to the number of sides. Each curved plate has a side portion for extending between respective edges of the end plates, a knife portion, and a junction portion at the junction of the side portion and the knife portion. First tab and slot connections attach the side portions of the curved plates to the edges of the end plates respectively. Second tab and slot connections attach the terminal edges of the side portions of the curved plates to the junction portions of adjacent curved plates respectively.

The invention relates to a wear-resistant roller (1) for crushing of particulate material, such as crude ore for use in the cement or minerals industry comprising a roller body (2), a wear surface (3) on the roller body (2) having an axial extension in an axial direction of the roller and a radial extension in a radial direction of the roller, the wear surface (3) comprising a primary fraction of matrix material and a secondary fraction of hard phase material suspended in the matrix material, wherein the secondary fraction of hard phase material in a central portion of the wear surface is higher than the secondary fraction of hard phase material in a peripheral portion of the wear surface seen in the axial direction of the roller. Also the invention relates to a method of forming such a wear surface on a roller body.

A method of forming a processor disk for a processor of materials may include providing a disk blank with a central portion and a perimeter portion, with the perimeter portion extending between the central portion and a circumference of the disk blank, the perimeter portion having a perimeter surface; and applying material to the perimeter portion of the disk blank to form a plurality of teeth on at least the perimeter surface of the perimeter portion. A processor disk may include a disk blank with a central portion and a perimeter portion, with the perimeter portion extending between the central portion and a circumference of the disk blank and having a perimeter surface divided into opposite side surfaces by a circumferential edge; and a plurality of teeth formed on the perimeter surface through application of material to the perimeter surface.

A recycling plant for gypsum plasterboard is disclosed having three roller crushers and three screens. The rollers can operate at varying rotational speeds and, as a result of the different rotational speeds of the rollers, the plasterboard pieces are comminuted such that the plaster of the paper or the carton is detached.
