Grinding • Grinding is the last stage in the comminution process where particles are reduced in size by a combination of impact and abrasion, either dry, or more commonly, in suspension in water. • It is performed in cylindrical steel vessels that contain a charge of loose crushing bodies (the grinding medium) that are free to move inside the mill, thus comminuting the ore particles.
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes, like the mineral processing. There are many different types of mills and many types of materials can be processed in them.
The line includes grinding mill heads, shells, gears and pinions, main bearings, trunnions, trunnion liners, and more for select machines. For certain designated parts, additional enhancements have been made for increased safety and reliability.
The heart of a grist mill was its grinding stones. Grinding stones were used in pairs. The bottom stone, or bed stone, was fixed into position, while the upper stone, or runner stone, moved. The stones were connected to the power source (water or wind) by a wooden counterwheel, or contrate wheel, wedged on the horizontal drive shaft, which ...
