CUTTING DEVICE

Abstract

When justifying the principle of operation and operating conditions of the crushing device, it is necessary to take into account the mutual influence of many structural, kinematic and loading parameters, taking into account the physical and mechanical properties of the processed material. The selection of the construction of the working bodies of the crushing device should take into account the linear dimensions of the rods, their configuration and strength under various types of deformations, which will allow, with justified kinematic and technological parameters of the machine, to grind the product with minimal energy consumption. Preliminary grinding of rods, carried out due to breaking on the part of two-stage toothed discs, must to increase the efficiency of the next grinding of the product by increasing the productivity of the machine that implements the second stage of the process, improving the conditions for particle capture by the feeding device and reducing the specific energy consumption. The proposed design of the crushing device allows you to obtain mixtures of a given granulometric composition, to achieve a reduction in the metal consumption of the structure and the energy consumption of the grinding process, and to quickly adjust the degree of grinding of the product.
