Advanced Ceramics Manufacturing | Processes
Diamond Grinding. Diamond grinding is a machining process which is carried out on a sintered part that needs to be tightly toleranced, needs an improved surface finish or to remove surface flaws and as such is an optional process. Final machining processes include grinding, cutting, honing and lapping and polishing. Each of these processes ...
Cement Manufacturing Process - Civil Engineering
The crushed raw ingredients are made ready for the cement making process in the kiln by combining them with additives and grinding them to ensure a fine homogenous mixture. The composition of cement is proportioned here depending on the desired properties of the cement. Generally, limestone is 80% and remaining 20% is the clay.
