Comparative analysis of the advantage of impact crusher
The driving system of the impact crusher adopts the way of 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 a keyless connection, so that the overall strength of the equipment is high, the use is convenient, the maintenance rate is low, and the size of the finished product can be adjusted. High efficiency, good safety performance, the discharging grain is polyhedron, and it is tightly combined with concrete, and the national high-speed regulations require the use of 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 low 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 chamber for counterattack crushing has enough crushing space, suitable for crushing large pieces of material. The angle of the counterattack plate can be adjusted to ensure that the material is at a proper angle when the counterattack plate and the rotor are repeatedly impacted, which effectively improves the crushing efficiency. , To reduce energy consumption in the crushing process, the impact board adjustment system also doubles as an overload protection device for the whole machine. When foreign objects (such as iron blocks, etc.) or unbreakable objects enter the crusher, the impact board can automatically rebound and bounce back. 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 is a three-part structure, only need to open the rear casing of the crusher, you can perform maintenance and repair operations such as replacing the hammer, counterattack board, and lining board.
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 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.
