1. Working Principle

The working principle of the double-shaft hammer crusher is to put the material into the crusher, and through the high-speed rotation and impact of the double-shaft hammer head, the material is crushed into uniform particles in a short time. The double-shaft hammer crusher has a double-shaft structure, consisting of two shafts, and several hammer heads are fixed on each shaft. The hammer heads are conical and arranged in double rows. After the material enters the crusher, under the rotation of the shaft, the double shafts rotate at the same time, and the hammer heads exert high-speed impact, friction, shear and other forces on the material to crush the material.

2. Structural composition

The main components of the double-shaft hammer crusher include casing, motor, double shaft, bearing, hammer head, screen, etc. Among them, the casing is an integral structure, and is equipped with double shafts, bearings, hammer heads and other components. The double shafts are composed of two concentric shafts, which are superimposed on each other in the middle to achieve relative movement. The hammer heads are fixed to the shafts through connecting rods, and the number of hammer heads and the crushing range can be adjusted according to actual needs. In order to control the particle size of the material after crushing, the crusher is also equipped with a screen, which can re-enter the crushing process with particles that do not meet the requirements.

3. Crushing process

During the crushing process, the material first enters the machine from the feed port, and after multiple impacts and shear forces of the crushing shaft and hammer, it is crushed into the expected particle size. In this process, the rotation speed of the double shaft and the shape, number, diameter and other factors of the hammer affect the crushing effect. At the same time, the physical properties of the material such as hardness, moisture, viscosity, etc. will also affect the crushing effect. Finally, the crushed particles are sent to the screen for screening to obtain the finished product that meets the requirements.

4. Advantages and disadvantages

The double-shaft hammer crusher has the advantages of high crushing efficiency, simple structure and convenient maintenance. At the same time, it also has some disadvantages, such as high noise, easy to generate dust, and poor controllability of materials. In addition, the double-shaft hammer crusher has high requirements for the hardness and humidity of the material, and it is necessary to select suitable equipment for the actual material.

[Conclusion]

Through the above introduction, it can be seen that the double-shaft hammer crusher is an efficient crushing equipment, which has been widely used in stone, coal, fertilizer, chemical and other industries. Being familiar with its working principle and structural composition and understanding its advantages and disadvantages can help us use and maintain the double-shaft hammer crusher reasonably and better play its role.
