Kani Sanat is one of the largest pin mill manufacturers and suppliers in Iran. Pin mill is a mill machine that grinds materials by action of pins that repeatedly move past each other, it breaks up substances through repeated impact.

It is a type of vertical shaft impactor mill and consists of two rotating discs with pins embedded on one face. The discs are arrayed parallel to each other so that the pins of one disk face those of the other. The substance to be homogenized is fed into the space between the disks and either one or both disks are rotated at high speeds.

Material is evenly fed into grinding chamber by feeding devices, strongly impacted by high-speed rotating disc. At the same time, it is subjected to various comprehensive forces such as friction, shearing and collision between the static disc and rotor disc to grind material. The rotor disc and static disc can be combined in different structural forms according to nature of material to meet the grinding requirements of different materials.
