Ends with a circular cylinder, cylinder fitted with hollow shaft end cover, end cover of the journal bearing on bearing, motor mounted on the cylinder gear through restore
ball mill, grinding medium in the cylinder body is equipped with (steel ball, steel rods or gravel, etc.) and by grinding ore, the total loading amount of cylinder 25-45% of effective volume. When the speed of the cylinder according to the rules around the horizontal axis of rotation, the cylinder body of the grinding media and ore in under the action of centrifugal force and friction force, was taken up to a certain height by the cylinder liner, then fall out of freedom are compared.in xie or throw down, to make ore impact and grinding exfoliation, shattered. Ore from the shell side of the hollow shaft neck to into unceasingly, and grinding the cylinder of the following product at the other end of the hollow shaft neck out unceasingly, the movement of the cylinder body ore is constantly into the ore using pressure. Wet grinding, the ore was taken away by the water. Dry grinding, the ore is to tube in vitro take breath away.
Ceramic
ball mill working principle of the motor through the reduction gear drive cylinder, cylinder body of crushed ore and steel ball by friction and centrifugal force role in cylinder rotation because of gravity after being lining board to a certain height, began to fall and diarrhea, ore under the action of impact and grinding crushed gradually. Crushed ore discharging outside part of the discharge tube. Discharge of mineral hitches in spiral classifier classification of qualified products, coarse sand through joint feeder back to continue to grinding in the
ball mill. Feeder continuous evenly feed, ore by continuous joint feeder evenly into the
ball mill, by grinding material continuously from the eduction in ceramic
ball mill. Ceramic
ball mill is grinding equipment work 24 hours a day. Grid type
ball mill working principle of the grid type
ball mill by the cylinder department, give KuangBu, row KuangBu, bearing, transmission and lubrication system, etc. Cylinder make use of end cover on the main bearing. Cylinder and the end cover on the inside lining with high manganese steel lining board, in mine side also install a grid plate, cylinder body according to the proportion in different size of the pinion, drives the cylinder on the big gear, restore mill, ore by feeder to into, via internal carotid set into the feed shaft grinding machine. After grinding of the pulp through the grid plate by the fan room to row ore mouth to above the levels of row ore mouth, make pulp mill. Due to the effect of lift long liters of the fan room, shorten the time duration of the pulp in the mill, so grid
ball mill is also called force row ore type mill. The structure of the overflow type
ball mill working principle of the overflow type
ball mill than simple grid type
ball mill, in addition to the certain structure different row ore terminal, the other all and grid
ball mill, the main difference is that there is no grating, row ore side on the inner surface of the hollow shaft bushing, equipped with screw rotation direction and the opposite party and grinding machine screw blade, the purpose is to prevent the water polo or coarse material ore block with pulp eduction, the overflow type
ball mill of mine is to rely on pulp itself above the bottom edge of the hollow shaft bushing and gravity overflow, so the cylinder body of the pulp level is higher than grate
ball mill.
