Crusher rotor block and crusher

Abstract

The invention relates to the field of mining machinery, and discloses a crusher rotor block and a crusher, aiming at overcoming the defects of such as easiness for material blocking, small crushing ratio, quick wear of wearing parts, and short service life in an old-fashioned rotor block. The rotor block consists of multiple sets of rotor disks, wherein each rotor disk is provided with an integrated web plate, and the web plate is provided with multiple sets of plate hammer supporting structures; each rotor disk is fixedly installed on the same shaft, and an angle is formed between two rotor disks. The crusher rotor block and the crusher disclosed by the invention has the advantages that the time when materials enter the crusher and impacted by a plate hammer in high-speed rotation is different, the crushed materials are thrown to a counter-attack plate at the other end of a crushing chamber along the tangential direction at a high speed and crushed again, and then rebounded from the counter-attack plate to the plate hammer, at the moment, the materials can be subjected to crossed impact and crushing between materials with materials crushed later, so that the crushing probability of the materials is increased, the crushing ratio is increased, the crushing efficiency is improved, and the yield is increased.

Description

[0001] The invention relates to the field of machinery, in particular to a mining machine, more specifically to a crusher. Background technique [0002] The impact crusher uses the blow bar on the high-speed rotating rotor and the impact hammer crusher uses the hammer on the high-speed rotating rotor to produce high-speed impact on the materials fed into the crusher cavity and crush them, and the crushed materials Throw it to the impact plate at the other end of the crushing chamber at high speed along the tangential direction, be crushed again, and then bounce back from the impact plate to the blow bar, and continue to repeat the above process. The collision between the materials will continue to produce cracks, loose and even crushed. It can be seen from the crushing process of the material that the blow bar plays an important role in the crushing of the material. In particular, the installation method of the blow bar is even more crucial. [0003] The rotor bodies of exis...

Problems solved by technology

[0006] For the rotor body of the impact hammer crusher currently on the market, the movable hammer head and the fixed grate bar are installed on the rotor body. The hammer head wears quickly, which increases the distance between the hammer head and the discharge grate bar, resulting in a higher output yield. Reduced, and easy to block
