  • Simple structure and easy maintenance

    Machine structure is simple, mainly consists of casing, the rotor and counter plates. You can replace parts and maintain through the device on the machine's top.

  • Energy saving and long service time

    The machine is with high crushing ratio, high efficiency and low energy consumption. The hammer is made of high chrome, impact resistance and abrasion resistance, effectively extending the service life of wearing parts.

  • Wide applications

    This crusher can process materials whose size below 500mm and compression strength less than 360Mpa. Therefore, PF Jaw Crusher is widely used in many industries, such as chemical, metallurgy, road and bridge construction and sand making and so on.

  • Final particle size adjustable and in good shape

    The machine with the discharge port adjusting device which can control the size of final material. Finished products with cubic shape, no tension cracks, can meet all kinds of sand and gravel aggregate grading standards.

Impact crusher crushing materials with impact force. When materials enter, crushed due to the high-speed impact of the blow bar and are thrown to the impact plates on the rotor for secondary crush. Then materials will be shot back to the blow bar again for the third crush. Process repeats until the materials are crushed to the required size and discharged from the lower part of the machine. Size and shape of the finished powder can be changed by adjusting the gap between the impact rack and rotor support. Impact crusher employs self-weigh security device in its back frame. When other objects enter the impact cavity, they will be forced out of the machine by the impact rack in the front and back of the machine.

 This product belongs to the mining area of mechanical design and manufacturing, especially belonging to the mine crushing machinery design and manufacturing field, with special reference to vertical multistage Crusher shaft fixed structures.

 
In actual using process in the, due to broken machine original design insufficient, broken box within if exists residues material started moments spindle overload easy fracture, lock tight nut easy loose led to runner upper and lower channeling moving damaged, wear Board and counterattack Board using life low, and wear Hou needs replaced, replaced Shi needs split Xia spindle, split Xia spindle is is complex of process, effects has broken machine of using efficiency and using life, also in actual using process in the effects to machine using stability, Design can easily be removed main shaft connected to the structure is an important technology that enhances the crushers life and stability.
 
This product is based on the lack of prior art discloses a vertical multistage Crusher shaft fixed structures for the inadequacy of existing vertical multistage crusher in actual use, adopts new spindle fixed structures to address the above problems, improve service life and stability.
 
This product is achieved by the following technical solutions:
 
Vertical multistage Crusher shaft fixed structures, including spindle, fixed to the wheel on the spindle, supports upper and lower bearings of spindle, which is characterized by: referred to fixed in the maze of dust-proof structure of the lower bearing housings, housings are through bolted housings, outer housings are welded base fixing with Crusher.
 
Top of the upper end of the spindle, wheel in order to prevent displacement of the wheel lock nut and seal lid, formation of the sealing cap with raised surfaces join the ring and lock nut.
 
Above, the usefulness of this product: the product is fixed through the use of internal and external bearing structure simplifies the disassembly process, improving efficiency. Increase top lock nut locking device to ensure the wheel at high speed, heavy load environment movement and continuous work in damaged condition. Crusher working in a relatively harsh environment improves stability, easy wearing parts replacement, and improve overall production efficiency and stability.
