Application Of Sand Field Crusher In Different Rock Crushing Production LinesLast Update:2020-05-07 07:22:10
Sand crusher is one of the most widely used crushers in rock crushing production. Compared with the traditional crusher, the sand crusher can better use the rock crushing work with different hardness and different materials, so the sand crusher has become the main core crushing equipment in many rock crushing production lines. There are a lot of rock materials, and the hardness is also from 1 to 7 degrees or even higher. How can the crusher in the sand field adapt to and maintain efficient production?
The rock is not easy to be broken, so the sand crusher with large crushing force needs to be selected; the rock with small hardness is easy to be broken, so the crushing force of the sand crusher can be adjusted to break. In addition to the crystal structure and hardness properties we talked about, there is also the abrasiveness of rocks. In general, when recommending the sand crusher to the customers, we often recommend the customers to select the crushing process of 3-break or 4-break of the sand crusher according to the requirements of their aggregate size when encountering rocks with strong abrasiveness and high work index wi. For the rock with low abrasiveness and moderate work index wi, 3-stage crushing technology is recommended.
For the rocks with high abrasiveness, when choosing the coarse crusher and medium crusher, the extrusion crusher can be used in the sand crusher, the open circuit production of the sand crusher can be used for the coarse crusher, the closed-circuit production of the sand crusher can be used for the medium crusher, and the closed-circuit production of the sand crusher can be selected for the fine crusher. For the rock with low abrasiveness, it is suggested to adopt open circuit production for coarse crushing and closed circuit production for medium crushing. For fine crushing, it is suggested to adjust the sand crusher according to the actual situation, so that the crushing effect will be better.
When it comes to the properties of different rocks, the first is the crystal structure of rocks, which is an important factor affecting the selection of crushers in the sand field. Generally, we will find that the granular structure of rock is easy to produce square stone, and the layered structure of rock is easy to produce flake stone, which determines whether we choose the laminated or the impact type of sand field crusher. In addition to the crystal structure, another important attribute is the hardness of the rock, which is also an important index to determine the crushing process and the selection of the crusher in the sand field. In practical application, generally, rocks with high hardness are not easy to be broken, so it is necessary to select a sand field crusher with high crushing force, while rocks with low hardness are easy to be broken, so a sand field crusher with relatively fine crushing can be selected.
