Ball Mill Is the Indispensable Equipment in Mining Industry

Ball mill is the key equipment of regrinding the material after the materials being broken .It is widely used in the cement, silicateproduct, new building materials, refractory material, chemical fertilizer, the dressing of non-ferrous and glass-ceramics industry. It is for dry grinding or wet grinding of all kinds of ores and other materials with abradibility .The ball mill noise control is to control the noise output of the ball mill in the process of crushing materials by the engineering measures and is also to control the spread and receive of the noise,which is in order to reach the required acoustical environment.Strong vibration and noise will be produced when the ball mill crushes materials and the noise can be up to about 100 to 115 dB (A),which does great harm to the operation workers and the surrounding environment.In fact, no matter which kind ball mill it is, a ball mill, a energy saving ball mill, a large ball mill, or a planet ball mill using in the university laboratory,a cement ball mil using in the cement production, the working principle of them are all basically simalar.So, the factors of affecting the revolving speed of them should have in common as well.The ball mill grind materials at the driving of revolution and autobiography and relying on the friction and collision of the grinding balls in grinding bowl .The higher the revolving speed, the greater the function of the friction and the collision.So when the ball mill works at the formal condition, the discharging grain is basically proportional with the revolving speed of the ball mill.The fine technology of the ball mill has brought a huge reform of the building materials industry and has promoted the development of the super fine technology in China.mining magnetic separator: http://www.chinafote.com/pro/p20.html
