The relationship between cone crusher lining and cone crusher capacity
Cone Crusher is a commonly used crushing equipment for medium-hard and above materials in mining crushing equipment and is widely used. There are four main factors affecting the capacity of cone crusher:
- The number of swings of the crushing cone
The number of swings of the crushing liner is one of the key factors affecting the capacity of the crusher.
Due to the restrictions of the meshing angle of the crushing chamber and the parallel discharge area, the crushed ore is mainly discharged along the inclined surface of the cone lining by gravity and vibration. When the number of rotations of the main shaft increases, the ore is easy to be discharged, but too high a number of rotations is not conducive to discharge. Therefore, the number of swings of the Cone Mantle has a certain restrictive effect on the improvement of production capacity.
- The length of the parallel crushing area
The parallel crushing area is the area that determines the uniform particle size of the cone crusher. The crushing capacity is related to the thickness of the material layer in the parallel area, and the thickness of the material layer is also directly related to the size of the discharge port. The increase in the length of the parallel area is conducive to the control of the particle size, but the discharge capacity is relatively reduced; the decrease in the length of the parallel area is conducive to discharge, but the crushing particle size is not easy to guarantee.
There are three types of cone crusher chambers (with different lengths of parallel zones): standard, short-head, and medium. At the same time, since the productivity of the crusher is mainly related to the nature of the ore, the performance and specifications of the machine, and the operating conditions of the crusher, and is also related to the configuration of the crusher in the production process, when other conditions remain unchanged, changing the operating conditions (adjusting the size of the discharge port of the cone crusher) will change the productivity of the crusher.
- T he size of the meshing angle
The angle between the cone mantle and concave of the cone crusher is called the meshing angle. The meshing angle is generally 22-23°, with an extreme value of 27°.
The crushing chamber type is affected by the meshing angle from the feed port to the discharge port, and is limited by the height of the crusher. The relative change of the crusher cavity has a certain impact on the crushing efficiency.
Theoretically, if the meshing angle is too large, the ore is easy to slip in the crushing chamber, which reduces the production capacity and increases the wear of the liner and power consumption. If the meshing angle is too small, the crushing chamber will be too small, the amount of ore contained will be relatively reduced, which will affect the output, and increase the manufacturing cost of the equipment and the height of the machine.
- Performance of cone lining (cone Mantle And Concave )
High-performance cone crusher lining has better wear resistance, impact resistance, high hardness and strong toughness, and can be used for a longer time, which also extends the replacement cycle of wearing parts, reduces downtime and replacement costs, and reduces transportation costs to a certain extent (reduces procurement frequency).
Chengdu Zhixin Refractory Technology Co., Ltd. melts the developed super wear-resistant compounds into manganese 13 or manganese 18 materials, which greatly improves the performance of cast wear-resistant parts and has a service life of 2-3 times that of similar conventional wear-resistant parts.
Combining the above four factors, except that the number of swings of the crushing wall has been determined according to the characteristics of the equipment and is not easy to change, the other three factors can be changed to a certain extent, especially choosing a super wear-resistant accessory is also particularly critical.
