Alcon Cement Plant is a two stream plant comprising of two parallel cement grinding units, Unit 1 of 13TPH capacity and Unit 2 of 17TPH capacity. The raw materials used in the plant for the manufacture of cement are clinker, slag and gypsum.
Cement manufacturing - brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.

More than 30 raw materials are known to be used in the manufacture of portland cement, and these
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.
Raw Material Vertical Roller Mill is a type of industrial equipment used to crush or grind materials into small particles. Our raw materials vertical roller mills are widely used in the concrete and mining fields, and are also used to process gypsum.
Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process. The two processes are essentially alike except in the wet process, the raw materials are ground with water before being fed into the kiln.
Manufacturing of cement involves various raw materials and processes. Each process is explained chemical reactions for manufacture of Portland Cement. Cement is a greenish grey colored powder, made of calcined mixtures of clay and limestone. When mixed with water becomes a .
