Bush scraping techniques ball mill is the material to be broken, and then the key equipment for grinding. As a key equipment Mineral production, the quality of a dry ball mill offer its health directly affect the yield and quality of beneficiation. Main bearing is an important part of the ball mill, the main event of burning bush incident, we need to be scraping the tile surface. Ball bearing material currently use mostly Babbitt, has good toughness, less wear and impact resistance. Some tips scraping the ball bearing. A reasonable determination of the bush bearing zone bearing zone refers to the area of ??contact of the ball journal and the bush. Split sliding bearings to withstand radial load direction perpendicular to the surface should be split, bearing in vertical split surface area of ??about 30 degrees or less. Therefore, should the bearing of the main bearing area is set within the range of the lower portion of the contact angle of 60 degrees in the bush. Second, the optimum contact angle elect bush bush optimum contact angle should be 70 degrees to 80 degrees, while scraping the selected contact angle, ball mill into operation after a certain amount of the increase will occur dry ball mill parameters, because the ball hollow shaft radial thermal deformation when heated. If the bearing contact angle increases, the film is not well maintained, so that until the burning bush rapid wear. So to determine the initial contact angle of the bush and to ensure good quality of scraping. In determining the wedge-shaped gap on both sides of the wedge-shaped gap refers to the bush bearing area of ??the gap (backlash), the backlash value is an important parameter of hydrodynamic plain bearings, its value by the speed, oil viscosity and bearing load of the shaft is determined. Ball is in the low-speed operation under heavy load, lubricant viscosity is generally greater, bearing backlash values ??generally range from 0.2 ~ 0.3mm of wedge-shaped gap. Fourth, the significant point is the significant point bearing zone scraping process of the final process of dry-type ball mill supplier before scraping point for a rough scrape. Take in the oblique moire method of points, points evenly distributed within each texture, which was the point should be clear, uniform and distinct feel. The good scratch pad installed, continuous heavy vehicles Turning two to three hours, so that was the point of full contact surface of the tile dry ball mill, while a preliminary hardened layer, thus minimizing bush restored after put into operation heating phenomenon. Type ball mill and the role of diaphragms of diaphragm plate play ball in the overall structure of what role, in the end there are several types, namely, nothing. 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, 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.
