Load acting on mobile concrete crusher is actually the inertia force and inertia moment generated by movable vertebrae and vibrator, which is a cyclical dynamic load, therefore, it is inevitable to cause crusher vibration. Vibration forms of concrete crusher are vertical circular vibration, horizontal vibration, pendulum vibration, as well as extraneous vibration which is caused by intense shock and vibration, among which, horizontal circular vibration is principal oscillation, and other vibration forms are relatively small, so we here mainly talk about vibration isolation system of horizontal circular vibration.

Body of concrete crusher is located on the isolation system if set shear elastic stiffness of vibration isolation system as K, total mass of material in concrete crushing machine as M, inertial force of concrete crusher in any horizontal direction as Fc, then the spring mass system of concrete crushing

The rock pulverizer machines play very important roles in the industrial development. According to size of feeding and discharging granularity, the stone crushers can be divided into three types: coarse crushing type, medium crushing type and fine crushing type. The commonly used machines for crushing stones are jaw crusher machine, impact crusher, used rock crusher, single-stage hammer machinery machine, crusher cone, double roller crusher and so on. In the selling process of stone crushers, we find that the price is a matter of widespread concern when the customers buy crushers. However, not all overpriced crusher is the best crusher. Then, what about the performance and price of stone crushers?

Hammer machinery equipment is also known as hammering machine, which is suitable for crushing stones with medium hardness. It has such features as big crushing ratio, even discharging granularity, less

Our national crushing industry has the wide prospect and better investing environment. The rock breaking machine can crush the material whose crushing hardness and comprehensive strength are no more than 320 MPA, and some practical stone and rock are just in this range in the reality, which can be crushed by the quarry machine. There is one deep relationship between the producing efficiency and hardness of the material. There are some miner including the gold, silver, lead and zinc, limonite, Ying quarry, which have the different hardness of various materials, so the size of the mineral material is different in the feeding granularity, and some elements above on will make a big difference to the producing efficiency of rock breaking machine.

There are so many mining manufacturers entering into the mining crushing market, which directly influences the complex brands and worse producing features, especially the quality of them which limits

The mechanical disruption has been the most popular crushing method for the mobile stone crusher in for many years.In modern times, the construction of the large scale coal base and the centralization of the coal preparing industry force the crushing equipment manufacturers to go the way of upsizing and intelligent development. In such case, the mechanical crushing starts to be the most common and effective grinding method. Moreover, the mechanical disruption method needs little cost of the manufacturers, which is the other key reason that makes it popular among customers.

Most crushing processes in the mine field are operated based on their own different working principles and these processes are mainly physical crushing procedures. Because the materials that need to be crushed are in large number and with high hardness, in daily mining life we often consider the mechanical disruption method to realize the ideal crushing results.
