Lattice-type ball mill uses 
 The lattice-type ball mill for grinding all kinds of ores and other materials are widely used in mineral processing, construction and chemical industry and other national economic sectors. 
 Lattice-type ball mill structure 
 Lattice-type ball mill discharge end in the cylinder body nesting grid, the surface of the inside of the hollow journal bushing equipped with anti-spiral blades, slurry overflow ball and the crude ore block to return the mill. Typically, the cylinder diameter 900-2100mm ball mill or motor power less than 400KW, high starting torque of the Y series, and JR asynchronous motor drives, in the middle through a reducer and coupling connection. 
 The ball mill motor power of the large size is greater than 400KW, the a dedicated TDMK type low-speed synchronous motor, pneumatic clutch and pinion links to achieve single-stage reduction drive, the drive cylinder rotation. Pneumatic clutch, making the joint stable, and can motor - the host sub-pneumatic, and reduce start-up power, to improve launch conditions through do not have to wear clearance adjustment, large torque, the clutch quickly, to facilitate self-control and remote control, can play an overload insurance role. 
 The drive shaft into a double row bearing radial spherical stick peripheral gear to large modulus alloy cast steel helical gears, and thus the smooth transmission, low noise, long life. The large gear with dry oil atomizer jet quantitative periodic grease to gear the work surface, in order to achieve lubrication. The cylinder diameter 900-2100mm mill main bearings spherical bush bearings, cylinder diameter of 2100mm above who is completely enclosed, self-aligning 120 .... rocker bearings and hydrostatic bearings, ie mill in from the rotary department before the start of high-pressure top, keeping a few minutes, stop the high pressure in the mill started, hydrodynamic lubrication, the formation of hydrodynamic oil film, greatly reduce the installed power can also be a corresponding reduction in starting current. The main bearing piston ring seal, with axial strips and grease to achieve a good seal. 
 Lattice-type ball mill features 
 The lattice-type ball mill equipped with a slow gear, the cylinder can get the speed of 0.1r/min to drive cars, repair, or loose load. Hydraulic jack device for repair from the top turning part, eliminating the need for expensive large overhead crane.
