Of course, in the end we need when it comes to the proper operation of the equipment used, and the equipment in use, we should pay attention to what the appropriate question, the only way we can get a better use of effects in use. Due to hammer the face of high load high-pressure working environment, we Henan Wanxiang Heavy hereby give you some knowledge about the hammer, the focus here is to tell you about the extent of damage to determine the replacement or not the hammer. Many users think that needs to be replaced when the hammer is completely broken when the hammer roller crusher uses, it is not often when we do not need to produce a batch job description requires roll crusher, hammer on the surface of some no problem, but in fact has been close to the edge of the fracture, and this time if we just work, then it may be forced to shut down for replacement work, not only a waste of time, but also increased the production inputs, so we Henan Wanxiang Heavy Simple to introduce points. A visual inspection: we can see or observe the help of a magnifying glass 30 times, the surface of the hammer if there rust, bumps, cracks and other phenomena, if there is, we need to be replaced or replaced. 2 non-destructive testing: This is a detection method we developed Henan Wanxiang Heavy own, the process is probably using magnetic particle inspection or ultrasonic testing and other methods, this can be more comprehensive testing deeper hammer performance is good. 3 Performance testing: performance testing here is mainly to detect hammer hardness and abrasion degree roll crusher, jaw crusher is squeezing and bending two jaw plates for use of materials, coarse and medium crushing various hardness materials broken machinery. Its broken body from the fixed jaw plate and movable jaw plates, materials Jibei crushing roller crusher models when the two jaws close, when the two left jaw nesting population is less than a block material discharged from the bottom. Its crushing action is carried out intermittently. This crusher due to simple structure, reliable and able to crush hard materials, etc. are widely used in mineral processing, building materials, silicate and ceramics and other industrial sectors, and cone crusher compared to less investment jaw crusher finished stone tablets, low production costs. Compared with the hammer crusher wear parts to use for a long time, high efficiency, small post-investment. Quality roll crusher, Xin Li Heavy preferred (certified), roll crusher provided by Gongyi City Heavy Machinery Manufacturing Co., Ltd. Xin Li. Gongyi City Xin Li Heavy Machinery Manufacturing Co., Ltd. (www.gyxljxc.com) is Zhengzhou, forgings leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
