Briefly describe the main characteristics of impact crushers
At present, the main types of crushers include high-speed impact hammer crushers, high-speed impact plate crushers, high-speed squirrel cage (rod pin) crushers, etc. According to the arrangement of the rotor and the number of hammer rows, it is divided into vertical type, horizontal type, single row, double row and multi-row type. Compared with other types of crushers (such as ball mills), high-speed impact crushers have the advantages of large crushing ratio per unit power, easy adjustment of crushing particle size, wide application range, small mechanical installation area, and continuous closed-circuit crushing.
Impact crusher is an ultra-fine crusher that uses a rotary body that rotates at high speed around a horizontal or vertical axis to violently impact the material, causing it to collide with a fixed body or between particles, thereby breaking the material. equipment. Therefore, it is widely used in the chemical, building materials, mining, pesticide, food, pharmaceutical and non-metal industries to crush medium-hard materials.
The main features of this impact crusher are
The forced ventilation inside the machine can play a grading role, and can diffuse heat. The machine has two crushing chambers in parallel, which is to achieve the goal of one machine. Two-stage crushing operation effect, in which the diameter of the rotor in the first crushing chamber is smaller than that of the second crushing chamber, and it is a radial blade. The longitudinal angle between the No. 1 rotor blade in each crushing chamber and the main shaft is approximately. one. Rotate and install in the discharge direction, with the rotor blades perpendicular to the main axis.
Replaceable blades made of high-hardness alloy are fixed on the blades. The cylinders of the crushing chamber are parallel to each other, leaving a small gap between them. The first crushing chamber and the second crushing chamber, and the second crushing chamber and the fan chamber are separated by adjusting rings. These two sets of blades respectively perform impact, grinding, shearing and counterattack effects of collision. The material crushing machine is equipped with a slag discharge system. During the operation of the machine, it can remove debris and residual difficult-to-grind stones in the machine, which is beneficial to To improve product quality, ensure normal production capacity, and reduce wear, it can be combined with micro-powder classifiers to form a variety of systems for different crushing requirements of various minerals.
