The counterattack sand blower has different working mechanisms and structural design characteristics. Let's follow the footsteps of the editor of Qingzhou Jianyuan Machinery Co., Ltd. to understand.
(1) The discharge particle size is uniform, the discharge is cubic, and the content of fine powder and dust is low.
(2) Low operating cost and low investment cost. The total weight of the impact crusher is lighter than the hammer crusher, the volume is small, the dynamic and static load value is low, and it can reduce the cost of civil engineering. At the same time, the required motor power is low, which can better reduce equipment power consumption and reduce equipment operating costs.
(3) The wearing parts of the impact crusher have long service life and low long-term operation cost.
Through the analysis of the above three aspects, compared with the hammer crusher, the impact crusher has the following advantages:
Advantage 1: It can handle materials with high moisture content without clogging
The impact crusher can better handle materials with large water content and reduce the blockage of the crusher.
When the water content of the material is too high, the feed tank and the impact plate of the impact crusher can be equipped with heating devices to prevent the material from sticking to the material. The impact crusher does not need to be equipped with a bottom screen, which can better reduce blockage. The hammer crusher cannot be heated to reduce material adhesion and needs to be equipped with a bottom screen, which increases the possibility of blockage.
Advantage two: wide material adaptability
The impact crusher is not only suitable for soft materials, but also for materials with higher hardness.
The plate hammer of the impact crusher is fixed on the rotor with a mechanical clamping structure, and the moment of inertia is large when the rotor rotates. Compared with hammer crusher (hammer head suspension), impact crusher has larger rotor momentum, which is suitable for crushing harder materials and has lower energy consumption.
The third advantage of the counterattack sand blower: a wide range of flow adjustment
The new model can conveniently and flexibly adjust the discharging particle size, and has a wide adjustment range.
The discharge particle size of the impact crusher can be adjusted in many ways, such as adjusting the rotor speed and adjusting the gap between the impact plate and the grinding chamber. The gap adjustment can be mechanically or hydraulically adjusted, and the gap can be easily adjusted by operating the button or the transportation control system on the spot using the hydraulic adjustment system. However, the adjustment of the discharge particle size of the hammer crusher can only be achieved by changing the bottom sieve plate.
Advantage 4: Less wear on wearing parts
The utilization rate of the metal hammer of the crusher is higher than that of the vulnerable parts of the crusher.
The wear of the hammer of the counterattack sand blower only appears on the side facing the material. When the rotor speed is normal, the feed will fall on the hammer surface (impact surface), and the back and sides of the hammer will not wear. There is almost no wear even on the side facing the material. And the bottom grinding rod is easy to replace. The metal utilization rate of the impact crusher plate hammer can reach 45%-48%.
