During operation, regular inspections should be conducted to observe the working condition and bearing temperature of each component of the jaw crusher. for large jaw crusher, the temperature of the sliding bearing usually does not exceed 60 degrees celsius to prevent melting of the alloy bearing bush and the burning of bush accidents when the.
1. before starting, all jaw crusher parts must be fastened installed. the tail traction spring is suitable loose, and the engine oil is installed in the swing bolster. 2. jaw rock crusher must test runours when first startup. it can be fed to work after the bolster temperature below 600.
When working at high temperature, the jaw crusher should always pay attention to the temperature of the bearing to keep it inood lubrication state, and pay attention to whether there are abnormalities in sound and vibration. if it is found to be abnormal,nd check immediately to find out the reason and confirm whether it is stuck by an.
Foraw crusher the thickness of the largest particle should not normally exceed 8085 of the gape. assuming in this case the largest particle to be crushed is 85 of the gape, then the gape of the crusher should be 45.70.85 53.6 cm and forhape factor of 1.7, the width should be 45.7 1.7 78 cm.
In the use of the jaw crusher thin oil system, the temperature of the oil return should not exceed 60 degrees. when the temperature is too high, we need to adjust the oil flow by adjusting the oil valve or use water cooling to reduce the temperature. this will ensure the work of its production.
Jaw crushers are primary crushers used in an ore processing or mining plants. the size of these jaw crushers is determined by the square or rectangular opening from the feed opening top of the jaws. for example, the 246 jaw crusher will have an opening of 246. while66 jaw crusher will have an opening of 56 square.
