    This phenomenon is due to the hydraulic station losing pressure leading the locking function fail, and then the adjusting sleeve rotates with the movable cone. If the operator does not find and deal with the problem in time, it will cause the blocking phenomenon. Above detailedly introduces the blockage phenomenon of cone crusher.For instance, high energy ball milling is a top down method using planetary ball mills. To obtain optimized milling parameters in a planetary ball mill, many trials are needed. Hence optimization of the milling parameters through modeling tools is necessary to reach economically efficient and time saving synthesis of nano fertilizers.

  • The Reason Of Ball Mill’s Uneven Discharging

    Self fixing ball mill liner characteristic. The self fixing ball mill liner is composed of a plate and a riveting plate. The assembly design is carried out by using the geometry of the liner itself and the barrel of the coal mill and the mechanical principle of the arch bridge. The liner has good self strengthening and self tightening ability.Speed. The slurry and ball charge adheres to the walls of the mill before cascading o at a given angle, causing impact and fragmenting the ore.
