The impact crusher is the mostly widely used in various fields, especially the mineral resource crushing and processing area and the construction area. As we all know, the impact crusher can crushing the materials through the mutual action of the impact plate, liner and the rotor. Therefore, in the crushing process, the rotor and impact is the key to determine if the materials can be effectively crushed. The crushing cavity tends to be larger and lower. The secondary impact plate should be left behind. In addition, the discharging mouth at the lower end should close to the center horizontal line of the rotor to increase the fine crushing effect. Impact crusher is an efficient crushing equipment of mining industry, an indispensable machine for each mining company. Due to its simple structure, easy operation, competitive price, impact crusher was favored by mining industry. There are many crushing equipment manufacturers all over the world, and their levels are notably different.
If the impact crusher is divided according to the impact plate of the crushing cavity, the first-stage corresponding impact plate is called the first crushing cavity. The secondary corresponding impact plate is called the secondary crushing cavity. The third-stage corresponding impact plate is called the third crushing cavity. As a result, the impact crusher with the three-stage impact plate can strengthen selective crushing by increasing the number of the crushing cavity to increase the crushing degree of the materials. Therefore, adding the crushing cavity and using low rotating speed of the rotor can reach excellent crushing effect, which can also reduce the attrition of the plate hammer.
The crushing ratio of the impact crusher mainly depends on the length of the impact routine. If the impact routine with three-stage impact plate increases, the crushing ratio will be great. We can get the products with finer particle size. However, the structure is very complex. The design of the impact plate of the impact crusher is the design of the crushing cavity, because the impact plate is the most important component to compose the crushing cavity of the impact crusher.
