Basic principle, milling process and typing of ball mill

　　First, the base principle of the ball mill work is mainly composed of a cylindrical cylindrical body, an end cap, a bearing, and a gear of the gear. Cylinder: a steel ball or steel rod having a diameter of 25 mm to 150 mm, referred to as a grinding medium, and its load is 25% - 50% of the entire cylinder. End cover: There is an end cap on both ends of the cylinder, which is connected to the tubular end flange, and there is a hole in the middle of the end cap, referred to as a hollow journal. Bearing: The hollow axial diameter is supported on the bearing, and the cylinder can rotate. Large tooth ring: fixed on the barrel. Second, the milling process introduces the milling operation in the spherical grinding machine, the body of the barrel is brought to a certain height with the rotation of the cylinder, the medium is loaded in the cylinder due to its own weight. Since the translucent impact of the medium; on the other hand, since the rotation of the grinding medium is in the cylinder, the grinding of the body and its insection of the bodies have produced extrusion and grinding of the ore, thereby Grate the ore. Ball mill steel ball (grinding medium) is tapered and rose to a certain height when the cylinder is rotated, and due to the gravity of the steel ball itself, the final falling along a certain track. The steel ball in the region is subject to the role of two power: one is applied to the steel ball in the tangent direction during rotation; one is opposite to the steel ball diameter and the force is opposite to the above force, this force The generation is caused by the sliding movement of the steel ball itself. The above two types have constituted a pair of power for steel balls. Since the steel ball is extruded in the middle of the barrel and adjacent steel balls, the force can make the steel ball in size unequal friction, steel When the ball is rotated with the cylindrical shaft, the ball is falling in the region, which is a powerful impact in the area in the region, and the ore is broken. It can be said that the ore is mainly affected by the effect of the grinding force, impact force and extrusion resistance. Third, the spherical spill of the ball mill: With the rotation of the cylinder, the material is gradually diffused to the right after the materials such as ore, and finally, from the hollow axis of the right side, therefore . Plaid type ball mill: This type of machine is provided with a plaid, consisting of several pieces of sector, with a hole width of 7mm to 20 mm, and the ore enters the lattice plate and the end cap. Inside, then the material is raised upwards, and the material delays the pulleys, and then the tapered block is retracted to the right to the hollow neck. Wind drain ball grinder: Material from the feed mouth into the ball mill, the grinding medium is impactedAfter grinding, the material is gradually movable from the grinding, the outlet end is connected to the air tube, in the system, in the system, the import of the separator, the selection machine, the dust collector, and the fan, when the wind discharge starts, the ball mill The body is relatively low and negative pressure, and the abrasive material after crushing, as the wind enters the pipe system from the discharge opening, the coarse particles will be separated by the powder, and the ball mill is re-supplied, and the material that has grinded. Recycling by the separator.
