The cement ball mill is a kind of cement grinding is mainly used for grinding the clinker and raw materials of the cement plant, and also for grinding various ores in metallurgical, chemical and electric power enterprises.
The Application : Ball mill is an efficient tool for grinding many materials into fine powder.. Ball Mill is used to grind many kinds of mine and other materials, or to select the mine. 2. It is widely used for the cement, the licate produce, new type building material, chemical fertilizer, blak and nonferrous metal glass, ceramic and etc.
Jul 18, 2016#0183;#32;Ball mills have been the traditional method of comminution in the mineral processing industries and continue to operate with old generation classifiers, their maintenance sometimes neglected. This in combination with an inefficient operation translates into high energy consumption and low production. The consumption of energy by the cement grinding operation amounts to one third of
Energy Saving Mining Ore Gold Iron Copper Ball Mill With . Ball mill is widely used in mining smeltingroadbuilding material and chemical It is the key equipment for grinding after the crush processThe mill consists of feeding device driving assembly rotating assemblybearing unitdischarging assembly and foundation unitThere are two discharging type wet grid ball mill and dry grid ball mill.
Cement vertical mill is pressurized by hydraulic system, and the pressure acts on the material between the grinding roller and the grinding disc to achieve the purpose of grinding, vertical High grinding efficiency, 2030% energy saving than ball mill; can simultaneously dry materials with up to 10% moisture; product fineness is easy to adjust
In the cement pre grinding system, the general trend in the use of roller press or specially used for grinding mill stand as a pre pre grinding, then the composition of grinding system with ball mill, this combination of high grinding efficiency, energy saving and had no effect on the quality of cement.

Multicompartment ball mills are relatively inefficient at size reduction and have high specific energy consumption (kWh/t). Typical specific energy consumption is 30 kWh/t in grinding of cement. Barmactype crushers found application as a pregrinder in cement grinding circuits operating with ball mills to reduce the specific energy consumption of ball millgrinding stage.
mill operations, the energy requirements for the OK cement mill is 3045 percent lower for cement grinding and 4050 percent lower for slag. The OK mill can contribute significantly to profitability and competitiveness. The design combines the drying, grinding, material conveying and separation processes into just one unit, thus simplifying the plant layout. The OK mill incorporates unique patented design
Coarse material will be back to ball mill to grind again, and qualified material will go to be packed by worker or packing machine. Advantage (1) It equiped with ceramic liners and grinding media is ceramic balls to keep free of iron impurity. (2) Special design, saving energy about 30% (3) Easy maintenance and operation (4) Low operating cost
VRM has been a more compact unit is quite smaller about the ball mills thus significantly reducing civil engineering cost about a ball mill plant. Ball mills are factory made and transported to the plant site of the buyer while VRM is built on the site of the cement plant. This helps to reduce cost and complicated logistics issues. The equipment cost is, however, higher for a VRM than a ball mill.
The grinding media balls in the ball mill are used in cement plant to help grind blocky or granular grindable materials produced in the cement manufacturing process, so as to achieve the effect of grinding. Vertical roller mill(VRM) and clinker grinding mill and other cement grinding mill are also very common in cement plant.
Grinding energy was approximately 50 per cent of the ball mill and the drying capabilities allowed direct processing of materials of up to 20 per cent moisture content. The main energy issue was the high power consumption of mill fans, with pressure drops of 100mbar not uncommon with high nozzle ring velocities (gt;70m/s) and internal mill circulating loads of gt;1000 per cent.
