As a commonly used rock crushing equipment, jaw crushers are widely used in mining, metallurgy, building materials, highways, railways, water conservancy, and the chemical industries due to their simple structure and large crushing ratio. So, how to use the aggregate jaw crusher correctly?
Preparation before startup
1. Carefully check the lubrication of the bearing, whether there is enough lubricating oil at the connection of the elbow plate, and whether there is blockage, oil leakage, etc.
2. Check whether all fasteners are loose, and adjust the tightness of the V-belt and locking the spring properly.
3. Check whether there are ore or other materials in the crushing chamber. If there are large materials, take them out to ensure that the stone jaw crusher starts without load. The feeding specification should not exceed 0.85 times the size of the feeding mouth.
4. Check all instruments to see if they are in good condition, and check whether auxiliary equipment such as feeder, belt conveyor, lubrication station, electrical appliances, instruments, and signal equipments are in good condition.
5. Adjust the discharge port to a suitable scale.
Details to Pay Attention to In Use
1. During use, if the jaw crusher machine is shut down due to the blockage of foreign matters in the crushing chamber, the motor shall be turned off immediately, and the machine should be turned on again after removing the blocked materials.
2. It is strictly forbidden to throw hard and unbreakable materials into the rock jaw crusher to avoid accidents and damage to the machine.
3. The materials to be crushed should be evenly added into the jaw crusher cavity to avoid side feeding or full feeding, so as to avoid unilateral overload or bearing overload.
4. The hydraulic electric interlocking system of the jaw crusher equipment shall not be removed under any circumstances, which is the guarantee for the safe operation of the equipment.
5. When the jaw crushing plant is running, people are not allowed to stand on the rotary surface of the jaw crusher plant, and the operator is not allowed to ake the large ore that enters the machine by hand.
6. Stop feeding before parking, and turn off the motor after the materials in the crushing chamber are completely emptied. Stop the vacuum cleaner and water supply system only after parking for five minutes.
7. Emergency shutdown: (1) the temperature of main bearing or moving jaw suddenly rises above 80°C. (2) The front or rear thrust plate is broken. (3) The belt bolt or other transmission parts are broken during driving.
Maintenance of jaw crusher
1. Always pay attention to check the crushing particle size of the material. When adjusting the movable jaw, loosen the T-bolt and tension spring first, and lock it after adjustment.
2. Check the motor and bearing every 2 hours to make sure whether the operation is normal. The temperature of the motor shall not exceed 60 ℃ and the bearing temperature shall not exceed 70 ℃.
3. Check the lubrication of the bearing and whether there is enough grease at the joint of the thrust plate to ensure good lubrication.
4. The lower part of the elbow plate should be cleaned frequently to keep no debris between the elbow plate and the movable jaw.
5. When one end of the jaw plate is worn out, it can be used in turn (depending on the specific situation).
6. Proper amount of grease should be injected between the elbow plate and the elbow plate seat.
7.Pay attention to the lubrication of the friction surface frequently and timely to ensure the normal operation of the jaw crusher and extend the service life of the equipment.
The correct use of jaw crusher can not only reduce the unnecessary wear of the equipment but also ensure the production quality of users. Therefore, if you want to know more about the jaw crusher, you can consult Nile Machinery online at any time.
