It is generally known that the main factors which will influence the process of mineral crushing can be divided into three parts, including the nature of ores, the performance of equipments, the operating conditions and so on. Next, Henan Hongxing Mining Machinery Co., Ltd will help you analyze these main factors in detail.
1. Natures of Mineral
The harder the ores are, the higher the compression strength will be, which will make the ores tougher to be crushed, and lead to a lower production rate. During the process of feeding, the bigger the ores are, the more fragmentation the material will be needed, and the lower the production rate will be. When there is too much content of water and mud in the ores, the ores will be easy to cohere and jam in the crushing chamber, which will make a large influence on the production rate, or even may cause the machine stop.
2. Performance of Equipments
Equipments types, nip angles, sizes, output sizes will have a great influence on the efficiency. For the crushers of the same kind, the bigger size is, the higher productivity becomes; the smaller nip angle and the bigger output size are, the smaller reduction rate is, as well as the higher productivity becomes. On the other hand, the smaller nip angle and the smaller output size are, the bigger reduction rate is, as well as the lower productivity becomes. If the nip angle gets too high, the ores will skip to the top when being crushed, which may even cause some dangerous accidents. If the nip angle gets to small, the reduction rate will be too low to meet the need of the crushing process. Thus, the size and position of nip angles must be definitely proper in the crushers.
3. Operating Conditions
Normal operating condition will be a basic requirement. The closed-circuit crushing can add some cyclic load during the process of feeding, which may thin the feeding size. The cyclic load plus the crushing can make the just qualified intermediate product. Thus, closed-circuit crushing can improve the production capacity under the condition of high ratio of reduction and high load coefficient. According to different hardness of ores, the production capacity can be improved 15% to 40% when working under the closed-circuit crushing condition.
