Jaw crusher is a commonly used stone crushing equipment. It can crush granite, basalt, limestone, river pebble, iron ore, bluestone, quartzite, construction waste and other materials. It is a common equipment in the market due to its model and price. Diverse and cost-effective, more popular in the market. Because the crushing equipment is generally severely worn, the repair and maintenance of the jaw crusher is also more important. Next, let the editor tell you about the maintenance strategy of the jaw crusher. 　
　
1, Before starting the crusher, check the condition of all parts, check whether the parts are loose, whether the bolts are tightened, and if the problem is found, repair it in time, so that the jaw crusher can operate stably.

2,  Before starting the crusher, carry out a careful inspection of the bearings to ensure that the bearings are lubricated enough. If the bearings are short of oil, they should be oiled in time. The dryness of the bearings will increase the friction of the equipment, which will aggravate the wear of the bearings and shorten the life of the equipment.
　
3,  When the machine is in operation, always pay attention to the operation of the machine, and pay attention to the equipment and instruments. If there is an abnormal situation, the equipment should be shut down technically, and the problem should be eliminated, and the situation should be eliminated. 　　

4,  When the crusher is started, it should be turned on before feeding, and the materials must be drained before being turned off, and the materials must not be left in the cavity. 　
　
5,  During the operation of the crusher, someone must be specially managed to avoid equipment problems that cannot be controlled in time. 　
　
6,  The crusher should feed evenly and the size of the feed should be appropriate. The uniform feed can ensure the smooth operation of the equipment, and the proper size of the material can avoid the equipment jam. 　　

7,  After the machine is turned off, the operating conditions and working hours of the equipment should be recorded, so that the replacement time of the vulnerable parts of the equipment can be estimated, and preparations can be made in advance.
