To improve the functional analysis of impact crusher based on customer satisfaction
1What is impact crusher
Introduction to impact crusher performance Impact crusher is divided into single rotor Impact crusher Double-rotor impact crusher and single-stage hammer impact crusher and composite plastic impact crusher. The impact crusher (impact crusher) produced by our factory can handle particle size not more than 120500 mm and compressive strength not more than 320 trillion The various coarse, medium and fine materials of ore and rock (granite, limestone, concrete, etc.) are widely used in industries such as hydropower highway artificial sand and gravel crushing. This series of impact crushing structures are specially equipped with high chromium hammers and special impact liners are suitable for hard rock The crushing is high-yield and energy-saving, the discharging particle size is adjustable, which can simplify the crushing process, and has the advantages of large crushing ratio and high crushing efficiency. The product shape is cubic and can be selectively crushed.
2Usage of impact crusher Application field and scope of impact crusher
Widely used in many sectors such as mining, smelting, building materials, highways, railways, water conservancy and chemical industry, crushing various materials with compressive strength not exceeding 320 MPa.
3 How to choose a counterattack crusher manufacturer, just like the customers request, you must choose different types of crusher equipment
First of all, it depends on the strength of the manufacturer. Reputation and scale depend on the manufacturers product quality, technical level, and maturity. Once again, we must inspect the manufacturers customer production site. The user site is more convincing. Finally, we must shop around, carefully inspect and choose carefully.
Main advantages of impact crusher
1) Simple structure, small size, light weight, large production capacity, low production cost.
2) Ore crushing along the joint surface , So the power consumption is low and the efficiency is high.
3) The crushing ratio is large, up to 40, so the crushing process can be simplified, and the three-stage crushing can be changed into two-stage or one-stage crushing, reducing the equipment cost of the concentrator .
4) It has selective crushing effect, and the particle size of crushed products is relatively uniform, and most of the shapes are cubic stones. It has a wide range of applications for the construction of high-speed road construction terminals and airports for bridge construction.
4 The working principle of impact crusher
The machine is a crushing machine that uses impact energy to crush materials. When the material enters the hammer action area, The high-speed impact of the blow hammer causes the broken objects to be continuously thrown to the counterattack device installed above the rotor to be broken, and then bounces back from the counterattack liner back to the blow hammer action area to be counterattacked again, and the material enters one or two from large to small The three counterattack chambers repeat the crushing process until the material is crushed to the required particle size and discharged from the lower part of the machine. Adjusting the gap between the counterattack frame and the rotor frame can achieve the purpose of changing the size and shape of the material.
5What problems will occur during the operation of the counterattack crusher
How to solve the counterattack Problems during the operation of the crusher
A. The bearing temperature is too high. Remedy
1) Check whether the grease is appropriate, the grease should be filled with 50% of the bearing housing volume %
2) Clean the bearing and replace the grease
3) Replace the bearing.
B. Knocking sound is generated inside the machine. Remedy
1) Stop and clean the crushing cavity.
2) Check the tightness of the liner and the gap between the hammer and the liner
3) Replace the broken parts.
C. The discharge is too large. Elimination method
1) By adjusting the gap between the front and rear impact frames or replacing the liner and the hammer
2) Adjust the position of the counterattack frame so that the gap between the two sides and the frame liner is even, and the liner on the frame is worn out, so replace it
