We had a failure of 22356C bearing on one of our rock crushers last the week The crusher has a 600 HP 1790 rpm motor that drives a 20 ton roll shaft at 487 rpm belt driven There was no previous indication of problem The driven side bearing got

Monitoring the crushing force as registered through the load on the crusher motors as well as the pressure on the hydraulic mantle adjustment mechanism will give forewarning of crusher packing problems before they affect your efficiency Also the finer the closed side setting the greater the proportion of fines produced

Crushers operate at high power force and capacity in order to produce the required materials This puts a great deal of strain on the crusher and its wear parts which operators must be aware of when carrying out maintenance Failure to do so may have a high impact both in terms of financial cost and potential loss of production

• Speed of crushing ranges between 125 to 425 gyrations per minute • Discharge from the gyratory crusher is continuous • Less maintenance is required as compared to jaw crusher • Power requirement is low Crushing rolls • Mainly used for extraction of juice from sugarcane • Two types Smooth roll crusher

damaged or fail This means that some 50 000 000 bearings are replaced every year due to damage and failure There are several reasons why bearings can be damaged or fail Generally speaking 1/3 fail due to fatigue 1/3 fail due to lubrication problems wrong lubricant wrong quantity wrong lubrication interval 1/6 fail due to contamination

Maximum reliability and minimal maintenance In addition to the spacious clearance of 530 mm 1 9 between the jaw crusher and the conveyor belt the crusher s bottom area is sealed with construction design prevents re bar from being caught by the crusher s member openings on the side frames also ensure easy
