Cement Clinker Processing Plant
Cement, powdered hydraulic inorganic cementitious materials. After mixing with water into a slurry, can harden in the air or in the water better harden and can sand, stone and other materials firmly cemented together, is one of the largest building materials industry in the application materials. Cement production with raw material preparation methods can be divided into dry (including semi-dry) and wet (including semi-wet) two. In either mode of production, milling machines are indispensable processing equipment used.
1.Dry production. The raw material while drying and grinding, drying or by first grinding the material into a mature way after feeding raw material powder dry kiln calcination. But there are also the raw material powder made from raw material amount of water added to the ball, into the kiln burning mature Lepol method, called semi-dry, still doing a production method.
2.Wet production. The raw materials plus gouache ground slurry after feeding wet kiln burning mature approach. There are also raw slurry dewatering the wet method, the block is made from raw material into the kiln burning mature approach, called semi-wet method, a still wet production.
1.crushing and pre-homogenization
crushing the cement production process, most of the raw material to be broken, such as limestone, clay, iron ore and coal. Limestone is the largest amount of raw materials for cement production, the larger the particle size after mining, high hardness, thus crushing the material crushing limestone cement plant occupies a more important position.
pre-homogenization of raw materials pre-homogenization technique is to keep the raw materials, to take the process of applying scientific stacker reclaimer technology to achieve the initial homogenization of raw materials, the raw material yard along with storage and homogenization function.
2.raw material preparation.
Cement production process, each producing one ton of Portland cement grinding at least 3 tons of materials (including raw materials, fuel, clinker, mixed materials, gypsum), according to statistics, the dry process cement production line grinding operations need to consume power accounts for over 60% of the whole power plant, where raw material grinding accounted for more than 30 percent, accounting for about 3% of the coal mill, cement grinding about 40%. Therefore, a reasonable choice of grinding equipment and processes, optimization of process parameters, the correct operation, control operation system for ensuring product quality, reduce energy consumption is of great significance.
