In the mineral industry, ball mill is widely used in metal and nonmetal mines, building materials departments of various grinding ore or rock. The cylinder diameter of mining ball mill 900 ~ 2100mm.Its main bearings is spherical tile bearing. Others that the cylinder diameter above 2700mm use a fully closed position of self-aligning,120 ° rocker-type bearings.The bearing adopts high-lead low-Tang low hardness babbitt.Water cooling pipes are laid under it.Bearing structure with a static pressure, use low and high pressure petrol station lubrication.Main bearing sealed with the outside world is through piston ring,with rubber and grease to achieve a good seal.In the structure,mine mill use a large gear radial seal and new technologies such as automatic spray lubrication. The mine used ball mill has the idling speed transmission device which can make the main engine obtain 0.15r/min the rotational speed.It is used in maintenance,crank and loose load.Meanwhile,the installment of jack support from the rotor when the overhaul. The main body of mine is a simplified low speed rotation structure which is horizontally installed on two large-scale bearings.Mine ball mill is by electric motor through speed reducer and peripheral bull wheel reduction gear or directly by the low-speed synchronous motor through surrounding large gear reducer driving, actuates the rotor rotation. There is the appropriate grinding media inside the cylinder named steel ball.Grinding media is promoted to a certain height, the state was falling down as falling or leakage under the function of centrifugal force and friction force.The grinding materials is given the material mouth to enter the simplified form continuously,crushed by the moving grinding media,also discharged the product outside the machine through the power of the overflow and continuous feeding for next process. shanghai zenith is the biggest ball mill manufacturer in China.
