What are the requirements of the temperature of the crusher when it is working normally?
Jaw crusher is mainly used as coarse crusher and medium crusher in mines, building materials, infrastructure and other departments. In accordance with the inlet width size is divided into large, medium and small three, the inlet width is greater than 600MM for large machine feeding port width in 300-600MM as midrange computers, the inlet width is less than 300MM for the minicomputer. Jaw crusher is simple in structure, easy in manufacture, reliable in operation and convenient in operation and maintenance. That is the vanguard, crushing production line as the saying goes, the train to run fast, thanks to the front belt, only the jaw crusher the head yield put up, crushing production line to increase production.
The jaw crusher bearing off the oil or oil injected too much; plug hole, oil and not fly; counterweight sheave position deviation, rack beat; abdapter axial moving; bearing wear or damage of the holder, the bearing temperature can cause the jaw crusher is too high. Aiming at the above problems, summarizes the corresponding methods: according to the instructions provided on time, quantitative gas; clean up oil holes and grooves blockage; adjusting the flywheel counterbalance position; removing rack bearing cover, lock bushing and remove the flywheel or Geneva, the replacement of the locking sleeve; replacement bearing; replace the end cover and the sealing sleeve, bearing cover or loosen the frame bearing seat at one end of the heating fuse, and embedded with the cover frame bearing seat is pressed into the groove, and then set on the bearing cover, remove block cover rotation. Jaw crusher, users need regular equipment overhaul, maintenance, in order to ensure the stable operation of equipment.
Long term operation of jaw crusher can cause troubles in bearings, linings, hammers, motors and so on. This paper briefly introduces the causes and Countermeasures of the excessive temperature of the bearing in the process of using the jaw crusher.
