Impact crusher is a new type of high efficient crushing equipment, its features are: small size, simple structure, big crushing ratio, low energy consumption, large production capacity, uniform product size, and selective crushing effect, is a promising device.

Hammer crusher is directly to the maximum grain size of 600-1800 mm in the crushing of the material to a period of 25 or 25 mm below the impact crusher. Hammer crusher is suitable for crushing medium hard in cement, chemical industry, electric power, metallurgy and other industrial sectors of the materials, such as limestone, slag, Jiao Tan, coal and other materials in crushing and fine crushing work.

The main difference between the impact crusher and hammer crusher machine:

The impact crusher and cone crusher comparison of crushing machine in a large space, make full use of the kinetic energy of the rotor rotating hammer impact crushing material, not only from the bottom up, and be thrown to the back board; plus hit back and forth from the crushed material produced by the collision of compound broken, multiple functions, high energy utilization rate, yield of low power consumption, consumption of metal less. While the hammer crusher hammerhead is along the direction of falling material, material from the upper to the lower crushing blow, small space, low utilization rate of energy.
The crusher hammer and the rotor is in rigid connection, a milling effect on material discharged before; hammerhead and hammer crusher is a free hanging on the rotor, encounter difficult broken material, to avoid the protection of rotary, hammer is not damaged, but not to the crushing effect.
The impact crusher four characteristics and application in limestone discharge port no grate control, discharging smoothly, large production capacity, product size uniformity, easy to be the bulk material into small pieces of material, but it is not easy to put small materials become smaller, the need to change the rotor speed to control the particle size of the product; crusher products - cubic bulk, grain size in 5 ~ 10mm, no hammer crusher grate control products of fine grain size and uniform.
The back end of crusher counterattack plate is the use of live hinge rod hanging on the shell, the other end of the position is fixed by hanging bolt. When there are difficult to crush materials or iron clamp between the rotor and the impact plate, a movable hinge rod under pressure and ejection, counterattack plate along the back, the increase of the gap, can make difficult the broken objects through the rotor, hammer, protection from damage; then counterattack plate under the action of gravity, and back to the original position. Hammer crusher counterattack plate and no such safety device.
