Detailed Description
The present invention will be further explained with reference to the drawings and the embodiments.
The utility model relates to a permanent magnetism drive ball mill under at uniform velocity rotation state mainly comprises parts such as cylindrical barrel, bearing, driving pulley, belt, motor, rectangular electro-permanent magnet, little permanent magnet, and the non-metallic ceramic ball that does not have the magnetic attraction is packed into in the barrel. The two ends of the cylinder are provided with end covers which are connected with flanges at the end parts of the cylinder by screws, the middle part of each end cover is provided with a hole called as a hollow journal, the hollow journal is supported on a bearing, and the cylinder can rotate. In the driving device, a low-speed large-torque motor drives a cylinder body to rotate through a belt pulley and a belt. When the cylinder rotates, the non-magnetic ceramic balls attracted by the grinding body rise to a certain height along with the cylinder and then fall in a parabola shape or fall in a cascade shape. Because there is the cavity axle journal on the end cover, the barrel is fed into from the feeding section of thick bamboo in left side to the material to gradually right side diffusion removes, when the material from the removal in-process of left side right side, rotatory barrel will not have the non-magnetic attraction non-metallic ceramic ball to take to certain height and fall and smash the material, and the non-magnetic attraction non-metallic ceramic ball of a part becomes to cascade down the state at the barrel and has the grinding effect to the material, whole removal process also is the crushing process of material. The ball mill driven by the low-speed large-torque motor overcomes the defects that when feeding is carried out, large torque and large current enter a constant speed state, through power supply conversion, static long-strip electro-permanent magnets arranged below the cylinder body are powered alternately to enable small magnets distributed on the cylinder body to obtain suction in the tangential direction, and therefore the cylinder body rotates at a constant speed under the electro-permanent magnets and the suction of the magnets, and the purpose of saving power is achieved. The utility model relates to a rationally, simple structure is compact, operation maintenance easy maintenance, provides an effectual approach for energy-conservation and improvement ball mill grinding efficiency.
