Heavy introduction of design and manufacturing technology from Nordberg, USA, produced an ultra-fine crusher -rotary disc crusher. At present, foreign superfine crushers are almost all derived from cone crushers . Only such rotary disc crushers are designed for the production of fine-grained materials. It is capable of breaking a wide range of materials into a wide range of products with fine particle size and good shape, and is more efficient and economical than other crushers.
The crushing action of the rotary disc crusher is the laminating crushing between the particles, which is broken by the combined action of the mutual impact and grinding of the multi-layer material particles, is the particle-to-particle crushing, and the material is broken in the longitudinal direction. This machine is mainly used for the production of artificial sand, mixed sand, fine aggregate for asphalt concrete, dense material, cubic sand, sand for roofing materials, and can provide uniform feeding for rod mill and ball mill , thus improving the production of mill. ability.
The rotary disc crusher includes transmission, support sleeve, adjustment sleeve, eccentric sleeve, bowl bearing, crushing cone, distributor, liner, spring insurance and lubrication (Fig. 1). The rotational motion of the motor is transmitted to the eccentric sleeve through the pulley, the drive shaft and the bevel gear, causing it to rotate around the center line of the crusher. When the eccentric sleeve rotates, the crushing cone supported on the spherical bearing rotates around the fixed point, so that the lower liner sometimes approaches and then leaves the upper liner. Whenever the lower liner leaves the upper liner, the material from the distributor enters the grinding chamber from above, and the material is broken by the swinging movement of the body, and the pressure generated by the height of the material in the grinding chamber gradually makes the material gradually outward. Advance, and finally discharged through the grinding chamber from the discharge opening in the lower part of the crushing cone.
Model specification meaning example PP1213: P crusher, P - rotary disc type, 12 - broken cone bottom diameter (dm), 13 - throat size (mm).
The technical performance parameters of the PP-type rotary disc crusher are listed in Table 1. The equipment outline and installation dimensions are shown in Figure 2 and Table 2, respectively.
