The demolition of circular vibrating screen is an inevitably problems. Improper disassembly of shaker bearings may cause internal damage. Contaminants may enter and re-install the bearing will be possiblely error. Therefore, dismantling the vibrating screen bearings must be very careful, and the axis must have the appropriate support, otherwise forces demolished may harm the bearing.

Ways of removing the vibrating screen bearing
1.Removal of tapered bore bearings
Removing smaller bearings with adapter sleeve, crushing equipment for gold mining use stopper secured shaft to support the inner.After the nut back several times, using the pads with a hammer to beat demolished.
2.Shaker cylindrical bore bearing disassembly
Removal of the inner ring can pull out with the mechanical pressure. At this point, we should pay attention to make inner bear its pullout.
Inner ring disassembly of large shaker bearing is by hydraulic method. The hydraulic pressure to be set through the shaft hole, shredders used stone crusher so that the ease of drawing. Bearing width of the hydraulic method and drawing fixtures and use, disassembly operations.
NU type, NJ type cylindrical roller bearing inner ring disassembly shaker can use induction heating method. Local heating in a short time, so that the inner expansion after drawing methods.
3. the external demolition
Removing interference fit of the outer ring, prior to the housing outer circumference of the extrusion screw with a few screws, tighten the screws on one side equally. Removing the side. These usually cover screw holes blind plugs, low intensity magnetic separator shaker tapered roller bearings and other separation-type bearings, set a few notches in the housing block on the shoulders, use the pad, with press disassemble, or tapping the demolition.
