With modern quality of life continue to rise, some of the usual in life often applied, people are not aware of the high-tech products unknowingly have surfaced in people's eyes, for example: laser technology, cutting machine, etc., including a Some kind of crushing equipment, which is what we often say crusher machine. Today, we are concerned that specific categories crusher. First, it can be divided into two categories according to use: First, the application of the pharmaceutical industry, roll crusher, two mining crusher. We have the most contact, the most important is to see the mining industry applications in life. Pharmaceutical industry crusher is mainly applied the principles of resonance some strong crushing, to facilitate people's normal physical condition, reduce surgery brings risk factor; and mining crusher is mainly based on different industries can also look at classification, such as : Widely used in the construction industry, jaw crusher, mining crusher industry, as well as water conservancy common hydraulic cone crusher and so on. In conclusion With the development of society, the deepening industry segments, crushers also have a new breakthrough, he has been raised from a single model, one use, develop into a variety of models, a full range of crushing different purposes machine, and it has been widely used in various industries. Visible crusher will bring a different convenience for our future lives. Jaw crusher stone production line is kind of essential equipment, its performance has reached international advanced level broken equipment industry, Liaoning crusher, stone crusher is practical and reliable equipment. Following is a brief knowledge of several simple stone jaw crusher maintenance. 1, regular off the machine and check the machine for any broken jaw stone crushing equipment should be noted at the time of the switch machine off jaw broken machine regularly to check for wear inside the machine, such as: central feeding tube, cone hat, impeller, obscene Road liner plate, circular shield, wear wearable pieces of more serious immediate replacement of worn parts to repair these parts, taking care to replace the parts by weight of a certain type and size and other parameters according to the original replacement parts. 2, broken jaw broken jaw belts regularly cut stone production line conveyor is indispensable, belt drive machine is a credit to regularly adjust the tightness of the conveyor belt to ensure uniform force, dual-motor drive, the tape should be carried out on both sides of the triangle Optional grouping, each group will be the same length as his. 3, mechanical parts lubrication jaw crusher Mobil super car grease or 3 # lithium grease every 400 hours of adding the right amount of grease, open the spindle assembly work 2000 hours cleaning the bearings, the roller crusher general work 7200 hours, replace with new bearings.
