Different machines to meet all needs
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.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

HYDRATION OF CEMENT It is the reaction (s eries of chemical reactions) of cement with water to form the binding material. In other words, in the presence of water, the silicates (C3S and C2S) and aluminates (C3A and C4AF) form products of hydration which in time produce a firm and hard mass -the hydrated cement .

Jan 07, 2015 · In cement grinding the mill ventilation system fulfils two important functions, cooling the cement and removing the heat generated during the grinding process, and carrying part of the finished product out of the grinding area. It is well known that the energy used during the grinding process in ball mills is almost entirely converted into heat.

A considerable amount of energy is consumed for grinding during the manufacture of cement. Approximately 110 kWh/t of electric energy is consumed in the cement production. ... Thus, the mill feed rate was reduced and the retention time of the cement particles were increased, so the force acting on the unit material inside the mill was increased.
