Improvement measures for defects of jaw crusher

In view of the shortcomings of the current jaw crusher, the R&D personnel made preliminary improvements or made some suggestions, which is very beneficial to the improvement of the overall performance of the jaw crusher and to the greatest extent to meet the needs of users. Improvement measures for machine defects:

  • 1. The problem of energy loss caused by empty travel. For the non-production energy loss problem, it can be solved by the double-cavity jaw crusher, that is, a moving jaw plate and a fixed jaw plate are arranged before and after the moving body, and the front moving plate is empty and the rear plate is moved. It is the working schedule. This method not only reduces the loss of energy consumption, but also improves the crushing efficiency of the equipment.
  • 2. The problem of large material viscosity. When crushing materials with high moisture content, the anti-adhesive powder, such as ground dry ore powder or Australian soil, may be appropriately added to the inlet, and the accumulated material on the discharge plate shall be manually cleaned regularly to It is guaranteed to be unblocked, and the clogging rate of the discharge opening is reduced by more than 80%, which effectively ensures the continuous production of the crushing production.
  • 3. The problem of material returning to the feed inlet. According to the principle of mechanical analysis, the equilibrium condition in which the ore is clamped in the crushing chamber and not outside the extruder is that the various forces in the crushing chamber are balanced with each other, that is, the combined force in the crushing chamber should be zero. Therefore, in order to avoid the phenomenon that the material is ejected back to the feed port, it is necessary to make the jaw angle of the jaw plate to be less than 1 times the friction angle between the ore and the jaw plate.
  • 4. The problem of poor crushing effect of flat materials. The structural improvement of the gear plate and other accessories is carried out, and the contour peaks of the original lower section and the movable jaw plate are changed to high-tooth peaks of different corrugations. Here, Heavy Industry needs to be specially reminded that when the tooth height is improved to corrugated unequal height peak, the tooth peak width is still the original tooth peak width to ensure sufficient crushing ore bearing capacity and contact area during operation. At the same time, the corresponding E-plate corresponding to this tooth also adopts the concave-convex corrugated unequal height tooth peak corresponding to the same tooth to meet the needs of the original E-crushing and crushing ore, but the spacing of the discharge mouth (fixed and moved to the E The spacing) remains the same.
  • 5. The problem of screw damage. By strengthening the quality control, the quality of the heat treatment of the screw is ensured, and the uneven damage of the screw is avoided as much as possible. The damage rate of the improved screw is reduced by more than 50%.

The above improvements have been made to the defects of the jaw crusher, which better solves the problems existing in the operation of the equipment, improves the production efficiency, and provides an important prerequisite for the smooth development of the user project.
