Mine crushing plants, machine-made sand processing plants, quarries and many other industries related to crusher precision. The crusher is the core equipment of their production. The production cost and efficiency of the crusher are related to their survival lifeline. If the production efficiency of the crusher can be improved or the production cost of the crusher can be reduced, the competitiveness of these crusher related industries will be greatly improved.
In order to improve the production efficiency of the crusher, we must know the factors that affect the production efficiency of the crusher, and then we can correctly improve the production efficiency of the crusher.
Physical and mechanical properties of rock.
This is determined by the source of stone and the needs of the project.
1. The strength of rock In the process of crushing, the crusher mainly uses the compressive strength of rock as an indicator of the difficulty of crushing. Due to the relationship between Proctor hardness and compressive strength, and more intuitively reflecting the difficulty of crushing operation, rock classification is often carried out with Proctor hardness coefficient in engineering.
The greater the Proctor hardness coefficient of rock, the greater its compressive strength, the more difficult the crusher is to break, and the lower the crusher productivity. On the contrary, the smaller the Proctor hardness coefficient, the higher the productivity of the crusher.
2. The moisture of the material The rock contains a certain amount of water, which has no effect on the rock breaking. However, when the rock contains a certain amount of mud or the rock is broken to produce powdery particles, the fine particles or mud will agglomerate and sometimes bind to the coarse particles or the wall of the crushing chamber. Thus, the discharging speed is reduced and the productivity is reduced. In serious cases, the discharge port will be blocked, further affecting the production.
However, if the water content continues to increase, the polymerization force between small particles will decrease, making it impossible to have cohesive force. At this time, the productivity will be increased. Therefore, when crushing stones with high mud content, wet crushing can be adopted to prevent blocking.
3. Particle size composition of crushed stone When there are many coarse stones in the raw material, the crusher needs a large crushing ratio and consumes a large amount of crushing energy. Some large rocks in the crushing chamber need to be broken several times before being discharged, which takes a long time. Therefore, the productivity of crushing operation will be reduced. When there are many fine particles in the raw material, the productivity is higher.
Impact of crusher structural parameters.
The structural parameters of different crushers are different. It is very important to select a crusher with appropriate structural parameters to meet the needs of different rock crushing operations for the design and selection of crushing machinery.
1. Clamp angle of crusher.
The clamp angle is an important structural parameter of the compression crusher, which is the clamp of various crushers.
When the clamp angle is too large, the crushing chamber cannot hold the rock, the rock is easy to jump up and cannot be broken, and even a safety accident occurs. If the clamping angle is too small, the crushing ratio is too small to meet the technological requirements of stone crushing. Therefore, there should be a proper clamping angle.
2. Size of discharge port of crusher The size of discharge port will affect the clamping angle and crushing ratio of crusher. On the premise of meeting the use requirements, increasing the size of the discharge port can reduce the clamping angle and crushing ratio, and improve the productivity. On the contrary, if the size of the discharge port is small, the productivity will be reduced. The size of discharge port of many crushers is equipped with adjustment devices to adapt to different use requirements.
