      Product description

      Cone crusher:
      The crusher is a machine for crushing and grinding various materials. The cone crusher is a kind of crusher equipment. It is suitable for crushing raw materials in metallurgy, construction, road construction, chemical and silicate industries. And various ores and rocks above medium hardness. The cone crusher has large crushing ratio, high efficiency, low energy consumption and uniform product size. It is suitable for medium and fine crushed ores and rocks.
      With the continuous development of mining technology, cone crushers are also divided into several types, including spring cone crusher, rolling cone crusher, hydraulic cone crusher and composite cone crusher. PY cone crusher, Simmons cone crusher, composite cone crusher, standard hydraulic cone crusher, single cylinder hydraulic cone crusher and multi-cylinder hydraulic cone crusher and many other models.
       

      Working principle of the cone crusher:


      When the cone crusher is working, the horizontal axis of the crusher is driven by the motor through the V-belt and the pulley. The horizontal shaft drives the eccentric sleeve to rotate through the large and small gears. The cone shaft of the crusher produces the eccentricity under the action of the eccentric sleeve. Therefore, the surface of the broken wall is sometimes close to the surface of the fixed cone, and sometimes away from the surface of the fixed cone, so that the stone is continuously crushed, broken and impacted in the crushing chamber. The crushed material is discharged from the discharge port at the lower part of the crusher under the action of its own weight. The upper cavity of the cone crushing motor cone is supported on the spherical bearing shell at the upper end of the fixed main shaft, and the lower cavity is sleeved outside the eccentric bushing, and the movement thereof is directly driven by the eccentric bushing. When the eccentric bushing rotates around the main shaft, the moving cone not only rotates with the eccentric bushing around the center line of the machine, but also rotates around its own axis, which moves around the center of its spherical support for spatial swiveling motion. The axis of the moving cone intersects the center line of the main axis at a fixed point, that is, the center point of the spherical surface, and the angle between them is the precession angle. When the crusher is running, the axis of the moving cone moves in a conical surface with respect to the center line of the machine, and the cone top is the spherical support center, which remains stationary during the movement of the moving cone. Therefore, the motion of the moving cone can be regarded as the rotation of the rigid body around the fixed point, that is, the movement of the moving cone is composed of two kinds of rotary motions: precessional motion or implicated motion (rotational motion of the moving cone around the centerline of the machine) and rotation motion or relative Movement (the moving cone makes a rotational motion around its own axis).
      In the case of no-load operation of the cone crusher, the rotation of the moving cone is determined by the frictional torque of the spherical bearing and the frictional force of the eccentric bushing to the moving cone. If the torque is large, the moving cone is dependent on the torque. The direction is rotated. Under normal conditions, the moving cone rotates in the direction of rotation of the eccentric sleeve, and the rotation speed is determined by the difference between the two moments. The cone crusher adds a bushing on the moving cone between the spherical bearing and the lower cone of the moving cone to control the rotation of the moving cone. Under the condition of load operation, the frictional torque of the stone cone on the cone of the moving cone far exceeds the friction torque generated by the eccentric bushing on the moving cone. At this time, the moving cone takes the busbar as the clockwise axis along the material layer and the direction of the eccentric bushing. The opposite scrolling. This rotation of the moving cone allows the product to have a uniform particle size and uniform wear of the liner.

      Performance characteristics of cone crusher


      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 theory of laminating crushing of materials, the calculation method of the production capacity of cone crusher, 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 researcher analyzed the status quo of research and development of the 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 movement characteristics of the crushed material in the crushing cavity of the cone crusher were studied in depth, and the flow states of three different forms of particles were discussed. They were 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 studied in depth, and the crushing cavity structure of the cone crusher is optimized.
