How grinding wheel is made - material, history, used, parts

Grinding wheels are made of natural or synthetic abrasive minerals bonded together in a matrix to form a wheel. While such tools may be familiar to those with home workshops, the general public may not be aware of them because most have been developed and used by the manufacturing industry. In this sector, grinding wheels have been important for more than 150 years. For manufacturers, grinding wheels provide an efficient way to shape and finish metals and other materials. Abrasives are often the

cement manufacturing

Material is fed from inlet and ground materials discharged through the other end of the ball mill. For drying the material, hot air is introduced to remove moisture in the raw material. Grinding can be in two ways viz. closed circuit and open circuit grinding. In open circuit grinding, passage of material is only once through the mill.

BURNING 1. RAW GRINDING : The raw materials are very finely ground in order to produce the raw mix. 2. BURNING : The raw mix is preheated before it goes into the kiln, which is heated by a flame that can be as hot as 2000 °C. The raw mix burns at 1500 °C producing clinker which, when it leaves the kiln, is rapidly cooled with air fans.
