On the other hand, in practical work, blow bar bears impact force and stress is not enough, if the degree of hardening surface is not enough, can’t be able to play the best wear resistance. Therefore, in the face of the material blow bar, it is easier to appear wear problem, the crusher also because of improper selection of structure, caused machine wear. There are a lot of blow bar structure form, so when we operate impact crusher, ready at any time to observe the vulnerability of the blow bar, once the wear should stop and repair timely.
Besides jaw crusher and cone crusher, according to specific situation, there may be sand making machine for fine size.For marble crushing, jaw crusher is often used in primary crushing process as marble pulverizer. Since marble has high hardness, cone crusher is suitable for marble crushing as secondary crusher. To summarize, marble pulverizer has jaw crusher, cone crusher and sand making machine. Through vibrating feeder, big marble stones are transported into jaw crusher. In addition, cone crusher is also important marble crushing machine. Zenith has PE series and PEW series jaw crusher that can be used in marble mining process.
As we know, cone crusher is very welcomed by the customers both in domestic and oversea area, it is widely used in mining , metallurgy , construction, cement and many other fields, and it is usually used as secondary or fine crushing equipment in the whole production line, so its safety operating principle not only very important for the person who operate it but also for its service life , here SBM most professional engineer will give you the excellent technical support about cone crusher’s safety operating principle.
This type of new and used stone crusher machine for sale is generally used with soft materials like coal, seeds or soft metallic ores. Since the hammers bars are rotating at a very high speed, the time for which the particles come in contact with the hammers is very small, hence here impact loading is applied. The shaft is considered to be subjected to torsion and bending. The mechanism applied here is of impact loading where the time of application of force is less than the natural frequency of vibration of the body. The grinding screen is also designed for optimal output from the crusher A performance model is also considered for the horizontal shaft impact crusher so as to find out the relation between the feed, the crusher parameters and the output parameters.
