Jaw crusher is a common stone crushing equipment, it can crush granite, basalt, limestone, river pebbles, iron ore, lime stone, quartzite, construction waste and other materials, in the market is a common equipment, because the model and price diversity cost-effective, more popular in the market. Because of the serious wear and tear of crushing equipment in general, the repair and maintenance of jaw crusher is also more important. Next, let me tell you about the maintenance strategy of jaw crusher. 　　1. Before starting the crusher, check the condition of the parts, see if the parts are loose, whether the bolts are tightened, and find the problem is timely repair, so that the jaw crusher can operate stably.
　　2. Before starting the crusher, make a careful inspection of the bearings to ensure that the bearings have enough lubricating oil, the bearings should be oiled in time if they are short of oil, bearing dryness will make the equipment bearing friction increase, which will intensify bearing wear and shorten the life of the equipment.
　　3. machine in operation, always pay attention to the observation of machine operation, the equipment instrumentation to focus on attention, such as abnormalities should be technically shut down equipment operation, was the problem, to exclude the situation.
　　4. When the crusher is started, it should be turned on * in the feed, before closing to let the material exhausted, not to let the material remain in the cavity.
　　5. crusher in the process of operation, there should be someone special management, to avoid problems with the equipment can not be timely control.
　　6. The crusher should be fed evenly, and the size of the feed should be suitable. Even feeding can guarantee the smooth operation of the equipment, and the size of the material should be suitable to avoid the equipment from jamming.
　　7. After the machine is shut down, to record the operation of the equipment and working hours, you can estimate the equipment wear parts replacement time, can be prepared in advance.
