Jaw crusher is also called jaw crusher, or jaw crusher for short. It is mainly used to crush various ores and bulk materials with medium granularity. It is widely used in mining, smelting, building materials, highways, railways, water conservancy and chemical industries. The maximum compressive strength of the crushed material is 320Mpa. So what are the reasons for the increase in temperature of the jaw crusher?

1. Bearing temperature. When the jaw crusher works at high temperatures, you should always pay attention to the temperature of the bearing to keep it in a good lubrication state, and pay attention to whether there is abnormal sound and vibration. If it is found to be abnormal, s and check immediately, find out the cause, and confirm whether it is stuck by a non-breakable object or the hammer head and other parts are damaged.

2. The temperature of friction parts. When the machine is running at high speed, the power consumed by friction is all converted into heat, which causes the temperature of the friction parts to rise. When lubricating oil is used for lubrication, it continuously absorbs heat from the friction surface to dissipate it, or supplies a certain amount of oil to remove the heat, so that the temperature of the friction surface is reduced.

3. Temperature of moving jaw. The jaw crusher uses the repeated movements of the jaw plate to squeeze the material to be crushed. The upper and lower parts of the movable jaw are close to the fixed jaw. After the material is crushed, the movable jaw leaves the fixed jaw and the product is discharged from the discharge port. It can be seen that the operating strength of the movable jaw is high, and the temperature of the movable jaw is prone to abnormality. When the temperature rises to a certain limit value, the jaw plate will be damaged. If necessary, certain measures must be taken to solve the abnormal temperature rise of the movable jaw and avoid the cause. Equipment failure causes downtime and reduces production efficiency.
