Embodiment 1

[0029] like figure 1 As shown, the coal gangue crusher of the present invention includes a rotating power mechanism and a main engine, and the rotating power mechanism is a motor 8 . The main machine includes an upper cover 9 and a base 3 , and more than two feeding ports 10 are arranged on the upper cover 9 . A cylinder 2 is set between the upper cover 9 and the base 3; upper and lower bearings are installed on the upper cover 9 and the base 3, and a rotor is installed between the upper and lower bearings, and the rotating power mechanism can drive the rotor to rotate; the rotor includes a main shaft 7 , more than two layers of disks 6 are set on the main shaft 7, and more than two hammerheads 4 are evenly distributed around the disk 6. The hammerheads 4 are hinged and fixed on the disk 6 through a pin Bearing pin 5 rotates.

[0030] An inner lining plate 1 is installed in the cylinder body 2, and the material of the inner lining plate 1 is high manganese steel, which is be...

Embodiment 2

[0033] In this embodiment, strip-shaped grooves 12 are provided on the working surface of the inner lining plate 1, and convex lines 11 are formed between each strip-shaped groove 12, and the surfaces of the convex lines 11 and the surface of the hammer head 4 are quenched by electron beams.

[0034] The electron beam quenching is carried out after the inner liner 1 is installed inside the cylinder 2 and the hammer head 4 is installed on the disc 6; the quenching environment is evacuated, the focusing current of the electron beam is 500mA, the accelerating voltage is 45KV, and the beam current It is 101mA, and the moving speed is 50mm / s. The quenching depth of the surface of the convex line 11 of the inner lining plate 1 is 1.0-1.5mm, and the surface hardness is 55-60HRC.

[0035] The edges of the protruding strips 11 are coated with inlaid alloy wear-resistant steel ribs by means of electric spark discharge. The alloy wear-resistant steel adopts YS2 hard alloy.

Abstract

The invention relates to a coal gangue crusher and belongs to the field of crusher equipment. The coal gangue crusher is characterized in that the coal gangue crusher comprises a rotary power mechanism and a main unit; the main unit comprises an upper cover and a base, and a feed inlet is formed in the upper cover; a cylinder is arranged between the upper cover and the base; an upper bearing is installed on the upper cover, and a lower bearing is installed on the base, a rotor is installed between the upper bearing and the lower bearing, and the rotary power mechanism can drive the rotor to rotate; the rotor comprises a main shaft, and the main shaft is sleeved with two or more layers of discs; two or more hammers are evenly distributed on the periphery of each disc, and the hammers are hinged and fixed to the discs through hinge pins and can rotate around the hinge pins. The coal gangue crusher is simple in structure, suitable for crushing big materials and capable of meeting the requirements of users for different discharging granularities and particularly for the medium discharging granularity; energy is saved, operation is easy, maintenance is convenient, the cost is low, and the service life is long.

Description

Technical field [0001] The invention is the field of crusher equipment, which involves a coal gangue crusher. Background technique [0002] At present, the common crushing equipment on the market include roller crusher, jaw crusher, cone crusher, counterattack crusher, vertical shaft shock crusher, etc.These crushing machines are mainly used for crushing processing of fine and ultra -fine materials.The crushing of coal gangsters with a large granular granularity uses jaw crusher.Because the crushing of large materials requires a large number of crushing equipment, the motor power is large, the useless energy consumption is high, and it is not suitable for small output requirements. [0003] In view of this, the applicant's design has developed a second -generation coal vermiculite crusher to solve the above problems. Invention content [0004] The technical problem to be solved by the present invention is to provide a kind of coal vermiculite crusher, which is a crusher with lar...
