Method of reducing energy consumption of crushers

The granular material in the crusher must meet the requirement of crushing, the strength of the material should be within the maximum strength of the crushing machine. In addition, in the crushing process, the broken cavity should prevent the iron block and other non-broken objects into it. When the material is mixed together, the material strength is uneven, the strength of the material will protect the strength of small materials, thus reducing the strength of small materials crushing probability and product granularity. And due to the strength of the broken cavity lining plate is not uniform, can eventually lead to uneven wear of the liner, affecting the normal operation of the crusher. Therefore, in order to improve the efficiency of the crusher, improve the force of the parts and components of the equipment, and give full play to the function of crushing in the crushing process, the uniformity of the material strength should be ensured as far as possible in the production process.

Experts according to the concept of laminated fracture analysis, when the bulk materials accounted for more than 40% of the crushing volume, can be in the crushing process to achieve complete laminated fragmentation. In addition, according to the full feeding condition of the crushing crusher and the uniformity of the jaw, when the filling degree of the material reaches 55%, it can completely meet the requirements of the lamination crushing.

The crushing method can realize the energy-saving purpose of the broken equipment. In order to maximize the energy utilization of the crusher, laminated crushing feeding needs to meet certain conditions, just as we mentioned above. It has been found that the energy saving and consumption of the equipment is more obvious when the granular material is in the 6-10 layer. Generally, the average grain size of the feed equivalent is about half of the maximum allowable grain size, so the material layer of the feeding layer is about 2. When the plugging layer in the crusher height is 93 mm, the average grain size of the material can reach 9.45 mm, so the feeding layer can be determined as 9.8 layers, and the blocking layer can meet the requirement of the optimum feeding layer. Therefore, it is not difficult to find that in the crusher, the more close to the block layer material feed layer to meet the best feed layer requirements, crusher will be able to achieve greater energy saving purposes.
