The layout of the wet ball mill is slightly different from other ball mill equipment. Here we will introduce what issues need to be paid attention to when installing the cylinder of the wet ball mill so that it can be installed correctly.

Wet ball mill

(1) Matters needing attention when installing the cylinder of the wet ball mill: Use large-scale lifting equipment to lift the cylinder of the wet ball mill to the zero-meter ground between the pulping building and the absorption tower, make a towing board for towing, lift the cylinder of the wet ball mill to the towing board, use a hand winch to tow the cylinder to the lifting position in the pulping building, clean the cylinder shaft neck, and wrap the shaft neck with plastic cloth. Before installing the main bearing, temporarily lower the cylinder to the temporary bracket between the two bearing bases. After the main bearing is installed and aligned, place the cylinder on the main bearing. Before the cylinder is in place, the bearing should be completely cleaned, and then the bearing should be covered with a white cloth. After the cylinder is lifted to the installation position and basically aligned, remove the white cloth.

 

(2) Inspection work after the wet ball mill barrel is in place: After the barrel is in place, check the main shaft level. The journal level is measured with a frame level. The measuring surface is the journal surface. The shaft level tolerance is 0.1%.

 

(3) Installation matters of the wet ball mill barrel: Install the bearing cover and the sealing felt. The felt should be cut straight and the interface should be stepped. The felt should be in even contact with the shaft and the tightness should be appropriate. Tighten the flange bolts and the felt pressure ring bolts. The radial clearance between the pressure ring and the shaft is even, usually 3~4mm.
