Cone crusher influence factors and performance improvement
Aug 16, 2018

1. The cone crusher cavity shape is a working space formed by the broken wall (moving cone) and the rolling wall (fixed cone). The shape of the cavity design has a significant impact on the economic and technical specifications of the crusher (productivity, energy consumption, particle size of the crushed product and the shape of the broken wall and the wall of the rolling mill). The unique design makes the final product more uniform, cube-shaped, and the wear surface of the moving cone is more uniform.


2. The working parameters of the crusher have a direct influence on the movement characteristics of the bulk material in the crushing chamber. The main performance is the influence of the spinning speed of the main shaft of the crusher on the moving state of the bulk material, and then the working performance of the crusher (productivity and particle size distribution of the crushed product) Etc.) has an important impact.


3. The swinging stroke of the crushing chamber of the cone crusher has an important influence on the working performance of the crusher. When the swinging stroke is increased, the actual feed compression ratio of each crushing layer of the crushing chamber is increased, the quality of the crushed product is improved, and the size of the discharge material is increased. During the swinging stroke, the actual feed compression ratio of each crushing layer of the crushing chamber is reduced, the quality of the crushed product is deteriorated, and the calibration discharge size is reduced. In terms of improving the quality of the crushed product, the swinging stroke of each crushing layer of the crushing chamber also takes a large value.


Hammerhead hot loading

The thermal assembly technology guarantees: 1 Before the cone cone is heated, the level is corrected on the support frame to ensure the horizontal and stable cone; 2 After the spindle is lifted by the vehicle, it must be perpendicular to the cone center line and the horizontal line; . Adjust the size of the inner caliper to 0.50~0.40mm larger than the actual size of the spindle. When the cone diameter shrinks to this value, the spindle is quickly loaded. After the spindle is assembled with the cone, the cone is prepared with the slag powder prepared in advance. The spherical bottom portion of the body is covered;


Performance improvement

The improvement of working performance of domestic cone crusher has become a new target of China's mining machinery processing industry. Experts at home and abroad on some basic research results of the cone crusher, the researchers will start from different perspectives of the working mechanism and working performance of the crusher, respectively, in the lamination crushing theory of the material, the calculation method of the cone crusher production capacity, the laminating cavity Detailed research on model, cavity design planning, particle size distribution of fractured products and multi-objective optimization design of cavity type:


1. The researchers analyzed the current status of research and development of cone crusher cavity type at home and abroad, and deeply understood the importance and urgency of optimizing the design of the cone crusher cavity structure and improving the working performance of the cone crusher.


The in-depth study on the motion characteristics of the crushed material in the crushing cavity of the cone crusher is carried out, and the flow states of three different forms of particles are discussed. They are the state of sliding, free fall, sliding and free fall. The influence of the moving state of the bulk material in the crushing chamber on the working performance of the crusher was analyzed. The trajectory of the bulk material in the crushing chamber of the cone crusher was simulated and analyzed. The stratified crushing characteristics of the cone crusher were obtained, and the crushing chamber was divided. The theoretical basis for layer research and design accumulation.


3. By analyzing the influence of the crusher cavity type on the particle size distribution of rock products, the calculation method of the particle size distribution of the crushed product based on the overall balance model is established, and the new calculation method of the cone crusher production capacity is inferred.


4. Dedicated to the development of high-efficiency laminated cone crusher. Based on the research of working mechanism and working performance of cone crusher, the design scheme of multi-objective optimization of cone crusher production capacity, crushed product granularity and cavity structure was established. Combined with the multi-objective optimization problem of the cavity structure of the spring cone crusher, the solution method of the multi-reputation target optimization model of the crusher cavity is deeply studied.
