Method for installing ore ball mill size gear

The axis of the main body of the beneficiation ball mill should be horizontal, measured at the top of the large flange of the hollow shaft at both ends, and the height should be consistent. When there is an error, the feeding end is allowed to be 1 mm higher than the discharge end. When the bearing seat gland of the hollow shaft at both ends is seen, the gap between the hollow shaft and the bearing gland should be substantially the same, and the gap between the inner and outer gland should be substantially the same.

The dressing ball mill can be installed in the transmission part after the main machine has been adjusted to a level. First check the quality of the assembly of the transmission part, mainly to check the concentricity of the pinion shaft and the low speed shaft of the reducer. Install and adjust the transmission section based on the ball mill's large gear. The tooth width of the pinion gear is evenly distributed over both sides of the tooth surface of the large gear. From the contact marks of the large and small gears, the contact marks should account for more than 60% of the total length, and the height of the contact marks accounts for about 40% of the full height. If the contact trace is biased towards one end of the flank width, it indicates that the flank is not parallel. If the transmission gear is crushed in a week, the gear clearance is too small, so the pinion should leave the big gear a little. After fixing the position of the ball mill, the center of the ball mill is used to determine the position of the auxiliary beneficiation equipment.

A fully re-equipped lab sieve at Chenwei Corporation contains a full range of screening  and fluid bed processing equipment that is readily reconfigured to simulate customer  installations for trials using supplied materials. All models of laboratory sieve are quick-clean  designs allowing easy access to interior components for rapid inspection, disassembly, screen changes and cleaning. Most notable is the lab's new, full scale, fluid bed processing  equipment for drying, cooling and moisturizing of bulk solid materials. The exclusive, circular vibratory design enables entire systems consisting of fluid bed processor, heater/cooler/moisturizer, blower and dust collector, to be self-contained on mobile frames with casters, offering  testing flexibility not practical with larger,  heavier, rectangular units of equivalent capacity.
