Comparative analysis of the advantages of impact crusher
The drive system of the impact crusher adopts a V-belt crusher with a motor mechanical coupling, which can effectively improve the starting performance of the motor and enable the motor to start and run smoothly. The belt drive mode can play a double overload protection function, and the motor power required by the drive system is low, which greatly reduces the operating cost. This drive scheme is economical, practical, high-performance, safe and reliable.
The impact crusher adopts keyless connection, which makes the overall strength of the equipment high, easy to use, low maintenance rate, and can adjust the size of the finished product. High efficiency, good safety performance, the discharging grain is polyhedron, and it is closely combined with concrete, and the national high-speed regulations use equipment. The impact crusher uses high-strength wear-resistant parts, and the key components use Torrington bearings and other national inspection-free products. The equipment is one-time investment and high efficiency.
Compared with the cone crusher, the impact crusher has less investment, fewer finished pieces and lower production costs; compared with the hammer crusher, the wear parts have a long use time, high production efficiency, and low investment in the later stage. The multi-stage counterattack cavity of the counterattack crusher has enough crushing space and is suitable for crushing large pieces of material.
The angle of the impact plate of the impact crusher can be adjusted to ensure that the material is at an appropriate angle when repeatedly impacted between the impact plate and the rotor, which can effectively improve the crushing efficiency. Step by step counterattack the crushing process can effectively reduce the energy consumption in the crushing process. The impact plate adjustment system of the impact crusher also doubles as the overload protection device of the whole machine. When foreign objects (such as iron blocks, etc.) or unbreakable objects enter the crusher, the impact plate can automatically bounce back and let the foreign objects pass through the crusher. , To prevent foreign objects (such as iron blocks, etc.) or unbreakable objects from damaging the equipment.
The blowback hammer is firmly fixed on the rotor, so the starting torque of the crusher is small, the dynamic balance performance of the rotor part is easy to control, and the disturbance force during operation is small. Start up smoothly. The frame part of the impact crusher is a three-part structure. Only by opening the rear casing of the crusher, maintenance operations such as replacement of the hammer, impact board, and lining board can be performed.
The exchangeability of counter-breaking parts is strong, and the variety of wearing parts is small, which is convenient for the procurement and management of spare parts. The hydraulic opening device is used for the opening and closing of the casing, which can effectively reduce the maintenance labor intensity, improve the maintenance work efficiency, and shorten the maintenance work time. The monitoring system of the impact crusher can monitor the operating status of the crusher at any time, and the monitoring signal can be interlocked with the main control system to ensure the safe and reliable operation of the machine.
