Factors in choosing second hand stone crusher equipment

Reasonable selection of crushing equipment can help producers solve many problems, but when choosing crushing equipment, you should not only consider one reason, but consider it in many ways. The crushing equipment is mainly affected by the type and hardness of the material, the water content, the degree of cleavage, the size of the incoming and outgoing materials, and the construction site and output should also be considered.

1, material type and hardness

Material type and hardness are an important principle for selecting crushers. The hardness of different materials is not the same. Mohs hardness is usually used to indicate the hardness of materials. Mohs hardness is divided into 10 levels. The higher the Mohs hardness, the harder the ore is and the more difficult it is to break, and vice versa.

2, the water content of the material

The moisture content of the material also affects the choice of the crusher. When the water content is too large, the fine material will agglomerate or stick to the coarse material due to the increase of humidity, thereby increasing the viscosity of the material, reducing the rate of discharge and making the productivity There has been a decline. In severe cases, it may even cause blockage of the discharge port, which affects the normal production.

3, the degree of ore hair removal

The degree of hair removal of the ore also directly affects the productivity of the crusher. When the ore is broken, it is easy to rupture along the cleavage plane, so the ore that breaks the haircut is crushed, and the productivity of the crusher is correspondingly much higher than that of the compacted ore.

4, the input and output granularity

The ingress and egress granularity is used to determine the type and crushing level of the required crushing equipment. If the content of coarse particles (large dry discharge port size) in the crushed material is high or the ratio of the maximum mass of the ore to the ore width is large, the crushing ratio that the crusher needs to achieve (the particle size of the material before crushing and after crushing) The ratio of the particle size of the material is large, so the productivity is reduced; if the content of the fine material of the crushed material (close to or smaller than the size of the discharge port) is large or the ratio of the maximum mass of the ore to the ore width is small, the crushing ratio to be achieved is small. Therefore, its productivity has increased accordingly.

5. Construction site

The size of the construction site is also one of the factors that people choose to consider. In addition, the location of the crushing equipment and the like also affect the selection of the crusher.

6, Stone Crusher Equipment Production

The amount of output is also an important indicator for determining the selection of crushing equipment. It is conventionally understood that the higher the output requirement, the larger the specification of the required crushing equipment, and the corresponding input and output will increase.

The problem that the customer has in the crusher is abnormal vibration. Let us now look at the main reasons for this phenomenon. Mainly due to the uneven feed or feed particle size of the artificial material being greater than the feed size of the crusher, and the presence of relatively high hardness metal in the fractured material.

So how to solve the vibration of the second hand stone crusher equipments? First, the feeder should ensure uniformity of the material at the time of feeding. If the uniform feed is accompanied by vibration, the inspection must be stopped to remove the metal solids in the material. After cleaning, check if the fixing screws are loose. If it is loose, strengthen it. Then check if the particle size of the broken material can meet the customer's crushing needs. If the demand is not met, it is usually because the rollers in the stone crusher wear a lot and do not change in time, resulting in a decrease in the roll breaking performance of the material.

The solution is to change the rollers while ensuring uniformity of the feed. In addition, the crushing particle size of the crusher should be reasonably adjusted to solve the problem of uneven particle size and large crushing ratio of the crushed material. This phenomenon can occur because the gap between the rollers of the crusher is large and some small-sized materials cannot be completely broken. The solution is to adjust the gap between the rollers for the discharge. The size has been adjusted. If the material particles are still large, then two stages of crushing need to be repeated.
