Description of Jaw Crusher
Jaw crushers can be used together with mine-selecting equipment and gravel processing equipment as well as used independently. The jaw crusher is used for primarycrushers and secondary crushers for crushing all kinds of minerals and rocks with compressive strength less than 320 MPa. The crushing form of this series jaw crusher is driven-squeezing style. Its working principle is: motor drives belt and belt pulley, makes moving jaw up and down through eccentric shaft. When the moving jaw is up, the angle between lining plate and moving jaw becomes large, and this will push moving jaw plate close to the fixed jaw plate. During this process, the material is crushed and ground, thus the crushing will be done. When the moving jaw is down, the angle between lining plate and moving jaw becomes small, the moving jaw plate will leave the fixed jaw plate on account of the effect of pulling bar and spring, and then the crushed material will be discharged from the lower opening of the crushing room. With the motor continuously rotating and the material periodically crushed and discharged by the crusher, the mass production can be realized.
however, Jaw Crushers are always working under extreme enviroment of pressure and temperature. During operation, 3 tips, we guide you on the maintenance of Jaw crushers.
1. Shut down jaw crushers after a period of hours (fix the time thereafter), check the machine gradually. Pay special attention to the primary wearing parts, such as fixed jaw
plate, swing jaw plate, side protection plates, toggle plate, spring ect. Replace some of them if neccessary according to the specification of the orginal one( the exact same dimention, material). Many times, that when you find the capacity become smaller, the problem might lies here.
2. The exchange of the wearing parts is quite neccessary, though another issue should alwaysbear in mind to make sure the smooth operation of jaw crusher. That is the
lubrication system around the bearings. It is wise to replace the lubrication oil every 400 working hours.
3. Last but not least, jaw crushers are drive by engines or motors through V-belts, thus, it is also important to check the fitness and well being of V-belts, and replace them in time.
