1. Crushing mechanism of impact crusher: Dry cement process limestone uses a single-stage impact crusher to crush the material along the joint level with impact kinetic energy, and the discharged material is in a uniform cubic shape. After the large pieces of material enter the crushing cavity between the impact plate and the rotor, they gain kinetic energy due to the rotation of the rotor part, and repeatedly impact between the impact plate and the rotor. They pass through the successive impact chambers, the secondary impact chambers and the bottom grinding chamber. Crushed to achieve the required discharge particle size.

2. Structural features of impact crusher: The multi-stage impact chamber of the impact crusher has enough crushing space and 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 a suitable angle when they repeatedly impact between the impact plate and the rotor, which can effectively improve the crushing efficiency. The step-by-step counterattack crushing process can effectively reduce the energy consumption during the crushing process. The impact plate adjustment system of the impact crusher also serves as the overload protection device of the entire machine. When foreign objects (such as iron blocks, etc.) or unbreakable objects enter the crusher, the impact plate can automatically retreat and bounce up, allowing the foreign objects to pass through the crusher. , to prevent foreign objects (such as iron blocks, etc.) or unbreakable objects from causing damage to the equipment. The plate 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. Starts smoothly. The frame part of the impact crusher has a three-part structure. You only need to open the rear casing of the crusher to replace the plate hammer, impact plate, lining plate and other inspection and maintenance operations. The parts of the impact crusher are highly interchangeable and there are few types of wearing parts, making it easy to purchase and manage spare parts. The hydraulic opening device is used to open and close the casing, which can effectively reduce maintenance labor intensity, improve maintenance work efficiency, and shorten 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. The drive system of the impact crusher adopts the method of electric motor + mechanical coupling + V-belt + crusher, which can effectively improve the starting performance of the motor and enable the motor to start and run smoothly. The belt drive method can play a dual overload protection function. The motor power required by the drive system is low, which greatly reduces operating costs. This drive solution is economical and practical, has excellent performance, is safe and reliable.

 3. Effects of using impact crusher Impact crusher has special working mechanism and structural design characteristics. In terms of performance characteristics, the impact crusher has obvious technical advantages compared with the hammer crusher: 1) The discharge particle size is uniform, the discharge material is cubic shape, and the content of fine powder and dust is low, which is especially suitable for the operation of vertical mills . 2) Low operating cost and low investment cost. The total weight of the impact crusher is lighter than that of the hammer crusher, with small dimensions and low dynamic and static load values, which can effectively reduce civil construction costs. At the same time, the required motor power is low, which can effectively reduce equipment power consumption and reduce equipment operating costs. 3) The impact crusher’s wearing parts have long service life and low long-term operating costs.
