Both the impact crusher and the hammer crusher crush the material through high-speed impact, and the appearance is very similar, so a lot of people can't understand the impact and the hammer. So let's see the advantages of impact crusher compared to hammer crusher.

Compared with hammer crusher, impact crusher has obvious technical advantages in structural design and performance application.

(1).The discharging granularity is uniform, the grain shape is good, and the content of the fine powder material and the dust is very low.

(2).The operation cost is low and the investment cost is low. The weight and dimension are smaller than hammer crusher, which can effectively reduce the civil construction cost. Moreover, the motor power needed is lower, which can effectively reduce the power consumption of the equipment and reduce the operation cost.

(3).The wear parts have a long service life, and the semi-automatic hydraulic roof opening device can help to carry out the inspection and maintenance of the equipment and the replacement of the wear parts is faster.

Through the above analyse, we can see the advantages of impact crusher compared with hammer crusher.

1.Can be used for treating materials with large humidity and few blockage

The hammer crusher can effectively deal with the material with large moisture content and prevent the blockage of the crusher. When the water content of the material is too large, the feed chute and impact plate can be equipped with heating device to prevent the bonding of the material. Impact crusher does not need to be equipped with bottom screen to prevent blockage. The hammer crusher can not use heating to prevent the material from sticking, and must be equipped with the bottom screen plate, which increases the possibility of blockage.

2.Semi-automatic Insurance Design effectively reduces overload risk and downtime

When the non-crushing material(such as iron block)enters the crushing chamber, the front and back impact frame is reversed, and the non-crushing materials are discharged from the machine;When the crusher back to work, the impact plate automatically returns to its normal working position by means of self-weight insurance device, thus avoiding the risk caused by equipment overload and the loss caused by shutdown and maintenance. Since the whole process is completed automatically, the manual shutdown cleaning and maintenance time is greatly reduced, and the production efficiency of the whole production line is greatly improved.

3.The range of discharge adjustment is wider and the adjustment of discharge size is easier.

A mechanical adjusting device is installed on the top of the impact crusher, and the size of the discharging particle size can be easily adjusted. And the hammer crusher can only replace the bottom sieve plate to achieve the purpose of adjusting the discharging particle size.

4.Slow wear and long life of spare parts

The impact plate is made of the composite process of high chromium material and wear-resistant material. Because the traditional linear plate hammer is easy to be worn, the impact surface of the plate hammer cannot be perpendicular to the material, and the crushing efficiency is rapidly decreased. The impact crusher adopts the crescent impact plate. This design not only has large impact force, but also the impact surface is more durable.

5.The hydraulic system is more convenient to control and maintain

The impact crusher adopts the hydraulic adjustment system, and can easily finish the clearance adjustment of the impact plate and the blow bar according to the operation requirements; the modular design of the wearing parts of the equipment is also provided with a hydraulic jacking device, so that the replacement operation of the wearing parts is easy, labor and time investment are greatly reduced,

We can have a better choice about the equipment after comparing the advantages of impact crusher and hammer crusher.
