Mineral mining crusher for mine

Abstract

The invention belongs to the technical field of crusher, and particularly relates to a mineral mining crusher for a mine. The mineral mining crusher comprises a rack and an impact plate, wherein a rotor is arranged in the rack, a rotating shaft frame uniformly sleeves the rotor, and plate hammers are arranged on the rotating shaft frame; the impact plate is connected with the rack through an impact frame, elastic wear-resistant blocks are uniformly arranged at the bottom end of the impact plate in the horizontal direction, elastic wear-resistant rubber plates are arranged on one side faces ofthe plate hammers, and wear-resistant steel balls are arranged in the elastic wear-resistant rubber plates; and elastic wear-resistant rods are supported on the other side surfaces of the plate hammers, the end parts of the elastic wear-resistant rods are hinged in installation grooves through hinge columns, and the end parts of the plate hammers are in extrusion contact with the elastic wear-resistant blocks during rotation. The impact force on the impact plate by materials can be increased by the upward swinging plate hammers, so that the impact crushing effect of the materials is effectively improved; the elastic wear-resistant rubber plates generates shrinkage vibration when the plate hammers swing upwards, so that the phenomenon that the viscous materials are adhered to the outer surface of the plate hammers during the crushing is effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of crushers, in particular to a mineral mining crusher for mines. Background technique [0002] The impact crusher is a machine that uses the high-speed impact of the blow bar and the rebound effect of the impact plate to make the material crushed by repeated impact. The blow bar is fixed on the high-speed rotating rotor, and several impact plates are arranged at different angles along the crushing chamber. When the material enters the action area of ​​the blow bar, it is first crushed by the impact of the blow bar for the first time, and at the same time obtains kinetic energy, and rushes to the impact plate at high speed. After the material collides with the impact plate and is broken again, it is bounced back to the action area of ​​the blow bar to be impacted by the blow bar again. This is repeated until it is broken into the required particle size and discharged out of the machine. [0003] When the ...

Problems solved by technology

[0004] In order to make up for the deficiencies in the prior art, this invention proposes a mineral mining crusher for mines. The hammer head and impact plate of the crusher are prone to sticky materials, which are prone to clogging or sticking to the blow bar, which in turn affects the efficient use of the impact crusher
