There are many types of crushing equipment. Different crushers have different performance characteristics. Different performance determines its scope of use. The following is a brief description of the characteristics of the impact crusher:
1. Crushing mechanism
After a large piece of material enters the crushing cavity between the impact plate and the rotor, it is impacted by the rotor to obtain a large kinetic energy. The impact is repeated between the impact plate and the rotor, and it is broken in stages in the impact cavity and the bottom grinding cavity Meet the required output particle size.
2. Structural characteristics
The multi-stage impact chamber of the impact crusher has enough crushing space, which is suitable for crushing large materials. The angle of the impact plate of the impact crusher can be adjusted to ensure that the materials are at an appropriate angle when repeatedly impacted between the impact plate and the rotor, thereby effectively improving the crushing efficiency. The step-by-step impact crushing process can effectively reduce the energy consumption in the crushing process.
The impact plate adjustment system of the impact crusher also serves as the overload protection device of the whole machine. When foreign objects (such as iron blocks) or unbreakable objects enter the crusher, the impact plate can automatically retract and bounce, allowing foreign objects to pass through the crusher, to prevent foreign objects (such as iron blocks, etc.) or unbreakable objects from damaging the equipment.
The hammer of the impact crusher 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 dynamic disturbance force during operation is small. Startup is smooth.
The frame part of the impact crusher is a three-piece structure, and only need to open the rear shell of the crusher, you can replace the hammer, impact plate, liner and other maintenance operations.
The impact crusher parts are highly interchangeable, and there are few types of wearing parts, which facilitates the procurement and management of spare parts.
The hydraulic opening device is used for opening and closing 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 operation status of the crusher at any time. The monitoring signal can be interlocked with the main control system to ensure the safe and reliable operation of the machine.
The drive system of the impact crusher adopts the method of motor + mechanical coupling + V-belt + crusher, which can effectively improve the starting performance of the motor and enable the motor to start smoothly. The belt transmission mode can play the role of double overload protection, the motor power required by the drive system is low, and the operating cost is greatly reduced. This driving scheme is an economical and practical driving scheme with excellent performance, safety and reliability.
