What are the advantages and disadvantages of impact crusher?

The advantages of impact crusher are as follows:

1. Simple structure and easy maintenance. The frame has a three-part structure. You only need to open the rear casing of the crusher to complete a series of maintenance and repair operations such as replacing the plate hammer, impact plate, and lining plate. The machine is small in size, light in weight, and easy to install.

2. Large crushing ratio, simplifying the crushing process. The crushing ratio is generally around 20, and the highest can reach more than 50. It can complete the medium and fine crushing or coarse, medium and fine crushing of materials at one time, saving investment and reducing production costs.

3. Selective crushing, high quality finished product. It can achieve selective crushing. Materials with high density will be crushed into small particles, and materials with low density will be crushed into large particles. The crushed products will have uniform material size, cubic shape and beautiful particle shape.

4. Parts are wear-resistant and have long service life. The blow hammer is made of chromium, molybdenum, and vanadium alloy materials with high wear resistance and high toughness, which solves the problems of difficult crushing of hard materials and rapid parts loss, and increases the service life of the entire machine.

5. Low energy consumption and high production efficiency. Low speed, multiple crushing cavities, a capacity of up to 800t/h, impact and impact crushing along the joint surface of the ore, because the impact strength of the material is more than ten times smaller than the compressive strength, so the impact crusher can be used compared to the jaw crusher Save 1/3 of the electric energy, compared with the roller crusher, it can save 1/2~4/5 of the electric energy.

The disadvantages of impact crusher are as follows:

1. The plate hammer and impact crusher wear more seriously, especially for ores with higher hardness.

2. The applicability of materials with mud and moisture content is relatively poor, and it is easy to get clogged in the rainy season in the south.

3. The finished materials are mixed with a small amount of bulk materials. The crushed materials cannot all move in a Z-shaped trajectory around the rotor. Affected by mutual collisions and other factors, they may move in the axial direction, causing a small amount of materials to escape from the crushing cavity axially without being fully crushed, affecting the overall finished product. the quality of.
