Here we will list some professional tips for using and maintaining the portable jaw crusher and the way of ruling out the trouble.
Jaw crusher as primary crushing equipment in the process of crushing, generally deals with the first time crushing for large materials because of its simple working principles, product durability, simple maintenance and crushing higher compressive strength. So it has been widely used in the field of broken.
Before starting the jaw crusher, we should best drive wheel to turn first one to two laps to confirm the rotation part well. In the work process of the jaw crusher we should pay attention to the temperature of the bearing parts. We should also make the bearing parts keep good lubrication and pay attention to the noise and vibration at work without abnormal situation. When there is abnormal sound or vibration, we should stop it and check whether jaw crusher parts are damaged.

In the using process we should also pay attention to the angle between fixed jaw of jaw crusher body and static jaw body which should has a proper scope. Usually the production efficiency is inversely proportional to the size of the mouth. So we need to adjust the angle according to the actual size.
In the work process of the jaw crusher we should keep feeding uniform and prevent instantaneous overload. We should also prevent the broken objects with materials such as metal and wood from going into the machine. Regularly check the jaw crusher whether the discharging granularity is in line with the requirements. If there is too much excess of the prescribed size of particles, we should find out why the gap is too large (such as bar, discharging mouth too wide, the hammer wear, etc.), and take the appropriate improvement measures. Power supply safety device should be kept in good condition. It is strictly prohibited to use unqualified materials in order to save trouble or money.
Before the end of the operation of jaw crushers, we should stop feeding and wait for the emptying of materials in the first row of net. We can cut off the jaw crusher power input.
Maintenance for jaw crusher: keep every month two minor repair, once a yearlong and once every three years the overhaul maintenance frequency. The major part of the jaw crusher should be paid special attention to being regularly checked, especially the dynamic and static jaw body due to its direct contact with the ore. We should keep replacing it periodically and regular maintenance. In addition, the temperature of the bearing and the use of bearing grease should also be noticed during jaw broken hardware maintenance. We must pay attention to that the bearing temperature cannot be higher than 70 ℃. If the bearing temperature is too high, we should check the lack of grease. After a period of use, we should also fix the anchor bolts. During the maintenance of jaw crusher, we should check whether the fastening bolts are strong and the wearing degree of the parts which is easy to wear. And we should give timely replacement or repair once we find the problems.
