Type ball mill and the role of diaphragms of diaphragm plate play ball in the overall structure of what role, which in the end there are several types of mill manufacturers, are what. Mill diaphragms role where reflect: (1) separate grinding: the average size of each bin is kept grinding gradually narrowing from the coarse grinding to fine grinding compartment to accommodate the coarse grinding process material with a large ball, Fine pellets with sound principles. (2) sieving material: diaphragm plate grate sew the material may be larger particle retention within coarse grinding compartment, Shenyang ball, it continues to impact crushed. (3) control of the material and flow velocity in the mill: the diaphragm plate grate slit width, length, area, slotted grate seam lowest position and arrangement of the mill degree of filling materials, materials, and flow velocity in the mill's and ball material ratio has a great influence. Mill diaphragms should try to eliminate the adverse effects of ventilation. Two types of partition board positions: (1) single-compartment plate: Usually there are several fan-shaped grate plate. The big end is bolted to the mill shell, small terminals are connected together with central panel and the other grate plate. It has ground to less than grate hole material, under the impetus of the new feed material through the grate seam to the next compartment. (2) Double-compartment plate: Usually by the front and rear grate plate blind panels, with the middle lift lifting devices. Material into the middle of the two board through the grate plate, by the lifting device lifting the material referred to the central cone to the next compartment. Department forced discharge, flow faster, without partition board positions around the filling rate effects, easy filling rate and with the ball, suitable for a warehouse. Double diaphragm plate types are transitional dual compartment, dual compartment and upgrade separator double compartment. Ball mill method to extend the service life of the material to be broken, and then to smash the key equipment. It is widely used in mineral processing, building materials and chemical industries. In operation, the mill price, due to various factors, they will wear the machine, in order to improve production efficiency of equipment, processing mill, it is necessary to improve their life. What, then, to extend the service life of the ball mill method is it? We analyze the following two points. The need for regular maintenance and repair 1, in routine maintenance, to determine fasteners use, regularly check the fasteners are loose and wear, and wear loose if it is necessary and timely for tightening and loosening replacement. 2, all lubricant release all equipment should be put into operation in a month, and then thoroughly cleaned, replaced with new oil. 3, liner bolts prone newly installed loose bolt in use for some time, will need to be checked regularly basis. 4, regular cleaning of equipment, keep the device clean, reduce dust on the ball damage. Correct use 1, requires a uniform feeding, to prevent a ball mill no material or material damage to the device attitude. 2. Strengthen the ball mill ventilation, to lower the temperature, thereby reducing the liner wear at high temperatures, increase equipment life. 3, the use of closed-circuit grinding, because the pellet mill closed within ratio, so the liner wear rate will correspondingly decrease. 4, using the initiative gear set overload protection. By this means, it is possible to predict and coordination, slow replacement of the drive gear reducer clutch operation. This can effectively protect the ball mill gear unit.
