What is an impact crusher?

According to different way of crushing, there are two types of impact crushes, one is Horizontal shaft impact crusher (HSI) and vertical shaft impact crusher (VSI). Their available configurations are stationary, portable, and track-mount.

An impact crusher features that high inertia rotor maintains proper penetration; large reduction ratio is achieved with maximum performance rotor. It is widely used in the primary, secondary and tertiary crushing process, and produces even and cubic products.

Impact Crusher Working principle

When the material enters the impact area of the rotor, it is broken by the high-speed impact of the rotor, and is thrown to the impact plate installed above the rotor to break again, and then bounce back from the impact liner to the impact area of the rotor to be broken again. In this process, the materials also collide with each other to achieve the effect of crushing.

This process is repeated until the material is crushed to the required size and discharged from the lower part of the machine.

Outstanding features of impact crushers

1. Hydraulic apron adjustment and overload protection system

It can keep track of the machine's running status, greatly improving production efficiency, saving a lot of costs.

2. Symmetrical design here is actually been engineered to be asymmetrical

When you get an elongated piece of concrete or asphalt or rock that is coming down the feed channel with the feed hopper, if the hopper is asymmetrical, the rock or the concrete hits first turns that piece and then it goes through the crusher without jamming up.

That's something unique to well solve the problems of bridging and jamming in these feed hoppers.

 

3. Heavy-duty blow bar is resistant to low temperatures

Each blow bar is made of high chromium, which enhances the capability of anti-impact and anti-wear.

The normal blow bars are at the range of 160kg-180kg while those engineered by Fote Company are 230kg, which increase the rotor efficiency by 80%. Besides, it also can run smoothly during at minus 20-30 ℃.

4. Entire frame of the conveyor belt is made from stainless steel

The reason we do this is that stainless steel is not magnetic so it does not take away from the magnetic forces of the over band magnet.

Track also manufacturers this section of the frame from stainless steel as well and that is also to not take away from the power of your band magnet.

So, you find that the magnets on these machines are extremely effective on pulling out almost hundred percent of the steel that comes in the outfeed material.

5. High-quality materials for the hammer

The choice of the plate hammer is particularly critical. The impact crusher is made of high chromium bimetal Cr26 which has good tensile strength and wear resistance, thus prolonging the service life.

6. Hydra arm lift

eliminates need for off-plant equipment to raise lid

allows for safe and unobstructed access to crushing chamber for maintenance

7. Direct drive system

It uses what we call a hydrodynamic clutch or a turbo clutch, so, there's actually a direct power transfer from the engine to the rotor. There's very little loss of power like there would be the through a hydraulic drive system from a maintenance standpoint.
