The single-stage hammer crusher system consists of a hammer crusher and a screening system: the advantages of the system are: simple process; easy maintenance and management; low land occupation; low project investment; low energy consumption per unit product. The disadvantages are: the product variety ratio is not easy to coordinate and the adaptability to the ore is poor, the use range is narrow; the product shape is poor, the amount of fine powder is large, the product acquisition rate is low; the crusher needs a large amount of dust collection; the consumption of wear parts is high .
It is mainly used in cement industry, mine stone crusher cement, aggregate production line and specific ore new production line.
This system consists of a jaw crusher, a impact crusher and a screening system. The advantages of the system are: the system has more capacity specifications, can be enlarged, and has a wide range of use; the product variety ratio is easy to adjust; it is suitable for medium grinding index materials. Disadvantages are: high energy consumption per unit product; poor adaptability to high abrasive index ore, medium grain shape, medium coarse particle size acquisition rate; stone crusher required large amount of dust collection; wear parts consumption cone Broken high.
This system consists of a jaw crusher, a cone crusher and a screening system. The advantages of the system are: easy to adjust the product variety ratio; suitable for high abrasive index materials; good grain shape, small amount of fine powder, high yield of coarse-grained aggregate; small amount of dust collected by the crusher; Low energy consumption; low consumption of wear parts. The disadvantage is that the cone crusher has fewer specifications. When the system capacity requirement is large, it requires three-stage crushing or more crushers. At this time, the process is complicated and the project investment is high; its use range is narrower than that of the impact crusher.
The system consists of a jaw crusher, a counter crusher, a vertical shaft crusher and a screening system. The process is basically the same as that of the jaw crusher + impact crusher system, but the stone crusher is added to the aggregate to meet the requirements. High quality aggregate customer needs. In addition to the advantages and disadvantages of the jaw crusher + impact crusher system, the system has the following characteristics: it can provide multi-quality aggregates to meet different customer needs, and the vertical shaft crusher produces more fine powder and can take into account the production mechanism sand; The process is complex, the project investment is high; the energy consumption per unit product is high.
The system consists of a jaw crusher, a cone crusher, a cone crusher and a screening system. The process is basically the same as that of the jaw crusher + cone crusher system, except that the first-stage cone crusher is added. In addition to the advantages and disadvantages of the jaw crusher + cone crusher system, the system has some features: it can meet the requirements of the system's output capacity; but the process is complex and the project investment is high.
Design the screening roller line before the initial crushing of the aggregate production line, so that the fine material and the soil that do not need to be crushed can be removed, and then the soil and the fine aggregate can be sieved out through the vibrating screen, so as to prevent the fine material from being broken again. By increasing energy consumption and increasing the amount of powder, the soil can be removed to reduce the dust in the subsequent process, and the quality of the aggregate can be improved.
The semi-finished material pile is designed between the primary crushing and the medium and fine crushing of the aggregate production line. The function of the semi-finished material pile is to balance the overall system capacity of the aggregate production line, and the specification of the medium and fine stone crusher does not need to consider the first crush. The fluctuation coefficient of the stone crusher; if the initial crushing workshop is overhauled, the downstream aggregate manufacturing workshop can be continuously produced; in addition, for safety, most mines are only mined in the day shift, and the downstream aggregate making workshop can still be operated twice. Production can flexibly meet market demand, and the number of downstream aggregates can be reduced by half or the equipment with small capacity can be matched with the upstream (because the semi-finished material pile can flexibly adjust the system capacity), which can reduce the system investment.
