Along with the development of the mining machinery ndustry in our country, there are many kinds of mining machines appearing in the market. So is the crushing machines. Such as jaw crusher, cone crusher, compound crusher and hammer crusher and so on. However, do you want to know among of them whose roror has large rotational interia?

Though our expert researching, they found that the impact crusher has the large rotational interia. Counterattack crusher is a kind of the use of impact energy to crushing material crushing machinery. The machine work, under the drive of the motor, the rotor high-speed rotation, the material into the plate hammer function area, and the rotor plate hammer impact crushing, and then again to counter device is broken, and then back to the board from the back plate hammer function area is broken again, this process is repeated, material from big to small into one, two, three, back cavity repeated broken, until the material being broken to the required size, is being exhausted from port discharge.This series against the ideal into the partical for 100-500 mm, maximum shall not exceed the specified value. Discharging granularity users according to need to adjust the hammer head and back plate, the gap between the parts and achieved.

What's more, the impact crusher has many its own unique performance features. They are in the following: 1. Inlet, high crushing cavity, to adapt to the material hardness, large blocks, less product powder; 2. The back plate and plate hammer gap can convenient adjustment, effective control of discharging granularity, grain shape good;3. Compact structure, strong rigidity, rotor machine with large inertia;4. High chromium plate hammer, impact resistance, wear resistance, impact large;5. Keyless connection, maintenance is convenient, economic and reliable;6. Crushing function, high productivity, all parts, low abrasion, high comprehensive benefit.




Of course, maybe my summary is not comprehensive. And we also have other mining machines, such as jaw crusher, ball mill sand maker and so on. If you have other supplement, you can comment about my article. We learn from each other, and make progress together. For more information, you can visite our website: http://sell-crusher.com.

With the development of the mining machinery industry, there are many kinds of mining machines coming out like the spring. So is the jaw breaker, which is also called jaw crusher. In additon, we have talked about simple pendulum jaw crusher and the compound pendulum jaw crusher. But do you know the other types of jaw crusher?

Today we will introduce the two more types jaw crusher. They are called mixed pendulum jaw crusher and finely jaw crusher. Then we will talk about them one by one. Mixed oscillating type (mixed pendulum type) Jane pendulum jaw crusher in order to overcome the shortcomings and compound pendulum jaw crusher, has developed the mixed pendulum jaw crusher, its working principle is shown in figure 1-1 (c).Movable jaw on the eccentric shaft together with the connecting rod, connecting rod head is installed in the middle of the eccentric shaft, and the moving jaw two axle casing is installed on both sides of the connecting rod head.Two thrust plate is still supporting the moving jaw and the lower end of the connecting rod and the frame of the wall.Moving jaw motion trajectory of each point is ellipse, its long axis tilted toward unloading direction, progress of material, and the material to the discharging mouth, improved the discharge condition, improved the crusher production capacity. While moving jaw level at the bottom of the swing and the ratio of the vertical swing for the 1-0. 8, it than type compound pendulum jaw crusher is reasonable, can reduce the toothed plate wear.Because of the moving jaw and connecting rod suspension on the eccentric shaft, eccentric shaft and its bearing force is very big, bad working conditions, easy to damage.Structure is more complicated at the same time, though the relevant domestic mining machinery works has made from mixed swinging type crusher, failed to promote because of above reasons.

And the finely jaw crusher machine is set to Jane, compound pendulum jaw crusher has made the improvement, with a number of dynamic jaw and a couple of partial column of eccentric shaft structure, running through every move jaw crushing material respectively, so as to reduce the load of the machine, and easy to start, a smooth operation, low energy consumption.At present domestic type compound pendulum jaw crusher and fine Jane pendulum jaw crusher, fine type with its working principle prototype crusher, just increase the length of the feeding port, the broken ratio can reach 5-8.The function of the type broken broken compressive strength less than 250MPa/cm2 of ore and rock.Its processing capacity (the machine calibration) in crushing medium hardness ore, rock, loose density of 1.6 t/m3 shall prevail.
