Factors affecting the ore crushing process

Core Tip: The factors affecting the ore crushing process are mainly ore properties, crusher operating parameters and operating conditions. Effect of ore properties: If the maximum particle size of the ore is coarse or the average particle size of the material is coarse, the amount of crushing work required is large.

The factors affecting the ore crushing process are mainly ore properties, crusher working parameters and operating conditions.

1. Effect of ore properties

If the maximum particle size of the ore is coarse or the average particle size of the material is coarse, the amount of crushing work required is large, and the crusher has a low production capacity, otherwise the opposite is true. In the process calculation, the particle size coefficient 虬 is used to indicate the effect of particle size on the fracture. The hardness of the ore is difficult to break, the crusher has low productivity, and the crushability coefficient A, 2 is used to indicate the effect of hardness on the fracture. According to the large capacity of the ore meter, the density factor r9 indicates the effect of density on the fracture. In addition, the ore with loose structure and good joint development is easy to be broken; the ore with large water content and large mud content is easy to bond and block the crushing cavity, which has a great influence on the crushing process.

2. Impact of crusher operating parameters

The type and specification of the crusher, the speed and stroke, the size of the discharge port and the angle of the joint have a great influence on the crushing.

The same crushing operation uses different types of crushers, and their production capacity is also different. In the case of the same ore and product granularity, the productivity of the gyratory crusher is 2-3 times that of the jaw crusher. In the same jaw crusher, the compound pendulum type is 20% to 30% more productive than the simple pendulum type. Even with the same type of equipment, productivity increases as the size increases. If the rotation speed is too high, the productivity will drop and the crusher will be clogged, especially the medium and fine crusher cone crusher. If the rotation speed is too high, the material will bounce due to the increase of centrifugal force and block the crushing chamber. Therefore, it is generally not necessary to increase the speed to increase the productivity. For crushers with large specifications, the adjustment stroke of the moving or moving cone is also large. To handle hard and brittle ore, a small stroke is required, and the soft and sticky ore should take a large stroke. Although the large size of the discharge port is large, the crushing ratio is reduced and the crushing effect is weakened. When the discharge port is large, most of the material is discharged without being broken. The discharge port is very small, although the crushing ratio is high, but the productivity is too low. Therefore, when the crusher works, it is necessary to consider both the crushing ratio and the productivity. Both of them can not be unilaterally pursued.

The size of the crusher discharge port determines the size of the crusher. The jaw angle (or the bite angle) of the jaw crusher. , refers to the angle between the movable jaw and the fixed jaw when clamping the ore. During the crushing process, the angle of the nail should ensure that the ore in the crushing chamber does not pop out. This requires sufficient friction between the ore and the face of the seesaw to prevent the ore from being squeezed out when it is broken.
