Main designing basis of the structure of impact crusher
In today's world in the field of mineral processing, the crushing and grinding energy consumption almost accounts for about half of the entire dressing process energy consumption. Therefore, the crushing and the grinding energy saving has become one of the important means to reduce the production cost and increase the economic benefits in the dressing field. However, the maturity of the crushing theory is a prerequisite for the crusher to achieve energy saving. Therefore, the development of the crusher machine depends on the development of the crushing theory. In the following paragraphs, the experts of Henan Hongxing Mining Machinery will detailed analyze the three crushing theories for the customers, which may be very helpful for the improvement of the working efficiency of the crusher machine.
Currently, there are two main types of the extrusion and fracture of materials, namely single particle crushing and the laminated crushing, which are also the main basis for the structure design and working mechanism of the impact breaker. This article will briefly explore the single-particle crushing and the laminated crushing.
First, the experts of Henan Hongxing Mining Machinery will introduce the single particle crushing for you.
The single particle crushing of the materials can be broadly divided into the following four stages. The first is the crack propagation caused by the stress concentration. The second stage is to generate a large number of micro-cracks. The third stage is to form the surface cracks. The forth stage is that the particles are crushed to form new surfaces.
Second, the experts of Henan Hongxing Mining Machinery will introduce the laminated crushing for you.
The laminated crushing is different from the single-particle crushing. The laminated crushing means that the crushing refers that a particle has contact with other particles. When the materials are crushed, the contact between the particles will produce the crushing form with interaction. The effective crushing stroke of the crushing cavity forms many particle layers with high density, then the sufficient crushing force is acted on the particle groups of the materials. When the laminated crushing is fully used, we can make full use of the kinetic energy of the crushing to crush the neighboring materials to obtain high crushing rate.
For the single particle extrusion and crushing, there are three different loading methods. When the materials withstand the point loads, the slope of the strain curve is small, which means that the curve is nearly flat. This is because the materials on the carrier point withstand the high partial pressure.
