(2) The ore is broken along the joint surface, with low power consumption and high efficiency;
(3) Keyless connection, convenient maintenance, economy and reliability;
(4) comprehensive crushing function, high productivity, low machine wear and high comprehensive benefit;
(5) The high chromium plate hammer has high impact resistance, wear resistance and impact force;
(6) Simple structure, small volume, light weight, large production capacity and low production cost. Large feed inlet, high crushing cavity and high hardness to adapt to materials;
(7) The crushing ratio is large, up to 40, so the crushing process can be simplified, and the equipment cost of concentrator can be reduced by changing the three-stage crushing into two-stage crushing or one-stage crushing. The back plate of the rotor can bear the extremely high moment of inertia of the rotor and the impact crushing force of the hammer.
2. The impact crusher with low rotation speed and multiple crushing cavities is designed by optimization, and its linear speed is 20%-25% lower than that of ordinary impact crusher, so as to obtain high production capacity with low energy consumption;
3. It has the function of three-stage crushing and shaping, so it has the advantages of large crushing ratio, cubic product shape, selective crushing and so on;
4. The plate hammer has reasonable structure, fast loading and unloading and multiple transposition, which can greatly shorten the time of replacing the plate hammer;
5. Using new manufacturing technology, the Cr-Mo-V alloy material with high wear resistance and toughness was successfully developed, which solved the problem of hard material breakage. Greatly prolongs the service life of the plate hammer;
6. Unique impact toothed plate, keyless connection, convenient maintenance, economy and reliability;
7. The impact crusher is equipped with a multifunctional hydraulic station, which has the functions of high-speed hydraulic discharge gap, stable vibration reduction of impact plate, automatic opening of the machine body and so on. 1, new wear-resistant materials make the service life of plate hammer, impact plate and liner longer;
2. The low and large inlet facilitates the layout of production line and increases the feed granularity;
3, the feed inlet is large, the crushing cavity is high, the hardness of the adaptive material is high, the crushing is large, and the product stone powder is less;
4, high chromium plate hammer, unique impact liner, especially suitable for hard rock crushing, efficient and energy-saving;
5, the hard rock is broken, which is efficient and energy-saving; The uniform plate structure makes the discharging particle size smaller and more cubic, and there are no internal grains;
6. The product is cubic, and the discharging granularity is adjustable;
7. Simplify the crushing process;
8, full hydraulic opening, easy to maintain and replace wearing parts; Impact crusher is named according to its working principle, that is, it uses the principle of impact crushing to crush materials. This is a thinner crushing equipment than the jaw crusher. It is mainly used for fine crushing of stone production line, and is used in conjunction with jaw crusher for crushing. Impact crusher has the following five advantages in the crushing process.
First, the impact crusher is more effective in treating materials with high water content, effectively preventing material blockage.
When the water content of the treated material is too high, the feeding trough and impact plate of the impact crusher can be equipped with heating devices to prevent the material from sticking. Impact crusher does not need to be equipped with bottom sieve plate, which can effectively prevent clogging.
Secondly, the impact crusher is suitable for a wider range of material hardness.
The plate hammer of impact crusher is firmly fixed on the rotor by mechanical clamping structure, and the moment of inertia is great when it rotates with the rotor. Compared with hammer crusher (hammer head suspended), the rotor of impact crusher has more momentum, adapts to crushing harder materials and consumes less energy.
Thirdly, the discharging granularity can be adjusted conveniently and flexibly, and the adjustment range is wide.
The impact crusher can adjust the discharging granularity in many ways, such as adjusting the rotor speed and the gap between the impact plate and the crushing chamber. The clearance adjustment can be made by mechanical or hydraulic means, and it can be conveniently completed by local operation buttons or remote control system with hydraulic adjustment system.
Fourth, the wear of wearing parts is small and the metal utilization rate is high.
The plate hammer wear of impact crusher only appears on the side facing the material. When the rotor speed is normal, the feed will fall to the surface (striking surface) of the plate hammer, and the back and side of the plate hammer will not be worn. Even on the side facing the material, there is almost no wear. The bottom grinding rod is also easy to replace. The metal utilization rate of impact crusher plate hammer can be as high as 45%-48%.
Five, the impact crusher spare parts replacement is simple, and the maintenance cost is reduced accordingly.
Only six plate hammers are installed on the rotor of impact crusher, and the plate hammers can be easily replaced with the designed special tools, and it only takes one shift to replace a set of plate hammers.
