Shanghai Dingbo Machinery currently has a variety of aggregate production lines, namely sand making production line, crushing production line, mineral processing production line, equipment production line, etc. In the secondary crushing process, the impact crusher plays an important role in the production line. Our
impact crusher is a new type of high-efficiency crusher, which uses my swirling impact energy to crush materials. It can handle all kinds of ores and rocks (limestone, dolomite, iron sulfide) with a particle size of no more than 120-500mm and a compressive strength of no more than 320pa. Medium and hard materials for mining, granite, limestone, concrete, etc. It has been widely used in mining, cement, chemical, construction, railway, energy, highway and all kinds of ore crushing. So what are the advantages of Dahua Heavy Industries impact crusher?
The wear of the impact hammer is only present on the side facing the material. When the rotor speed is normal, the feed will fall to the surface of the hammer (impact surface) and neither the back nor sides of the hammer will wear. Even the wear on the sides of the material is minimal. And the bottom grinding rod is also easy to replace. The metal utilization rate of the counting hammer can be as high as 45%-48%. The hammer crusher is suspended, and wear occurs in the upper, frontal, back, and side parts. Compared with hammers, the wear of hammers is more severe, and the metal utilization rate of hammers is only about 25%. In addition, the rotor body itself may be subject to wear and tear. The bottom screen of the hammer crusher was severely affected by wear, the baffle was completely replaced, and the job of replacing the screen plate was complicated.
2. Impact crusher is suitable for both soft materials and materials with very high hardness
The
impact plate hammer is firmly fixed to the rotor by a mechanical clamping structure and has a large moment of inertia when rotating with the rotor. Compared to hammer crushers, where the hammer head is suspended, the reverse breaking rotor has more momentum and is suitable for crushing harder materials while consuming less energy.
3. The spare parts of the impact crusher are easy to replace and the maintenance cost is reduced accordingly
Only 6 hammers are installed on the counter-rotating rotor. Special tools allow for easy hammer replacement. Changing a set of hammers requires only one gear. The replacement of the grinding rod in the bottom grinding chamber also takes only a few tens of minutes, which greatly reduces the time for inspection and maintenance, and reduces the cost. The hammer crusher has more than 100 hammers. Replacing a set of hammers takes a lot of time and manpower, and maintenance and maintenance costs are high. The change of the bottom screen is also cumbersome.
4. The
impact crusher can easily and flexibly adjust the discharge particle size and has a wide range of adjustment
The HSI crusher can adjust the size of the discharged particles in a variety of ways, such as adjusting the rotor speed and adjusting the gap between the subplate and the grinding chamber. Clearance adjustment can be mechanically or hydraulically adjustable, and the hydraulic adjustment system can be used to easily adjust clearance via local operating buttons or the ride control system. The hammer crusher can only adjust the discharge particle size by replacing the bottom sieve plate.
5. The impact crusher can effectively process materials with large moisture content and prevent the blockage of the crusher
When the moisture content of the treated material is too large, the feed chute and plate of the impact crusher may be equipped with heating devices to prevent the material from sticking. The impact crusher does not need to be equipped with a bottom screen to prevent clogging. The hammer crusher cannot be heated to prevent the material from sticking and a bottom screen must be provided to increase the likelihood of clogging.
