Installation of slow drives and hopper of bentonite grinding mill is similar to that of barite grinding mill, as follows:
Installation of slow drives subjects to the pinion shaft set; hoist slow is driven into place in workshop with the 16t lane, and installed strictly follow the slow drive installation instructions.After installation, hand movements should be flexible. Check the concentricity of slow drive shaft and pinion shaft coupling, and the clearance between shaft heads.
Before installation, surface of coupling flange should be cleaned, tension of tighten bolts should be even, and the connection of gaskets should be good to prevent leaking.Chassis of barite grinding mill should be horizontal, mounting bracket should be fixed perpendicularly and flanges in inlet and outlet should be horizontal.Misalignment of hopper and cylinder should be not more than 2mm.
Radial clearance between ends of short tubes and internal sleeve of hollow shaft should be equal on each side, upper part should be slightly larger than lower part, lift-side should be kept a 3mm axial clearance, axial clearance in bearing end should be less than 20mm.
After assemble of barite grinding mill lubrication system, tests should be carried out: the test pressure of each cooling water pipe should be not less than 0.45Mpa and no leakage within 30min; test pressure of high pressure pipeline is not less than the rated high pressure; oil return line should be tilted to oil tank and its gradient should be not less than 1:40.
