Description

Double roller of crusher

Technical Field

The utility model belongs to the field of machinery, especially, relate to carry out kibbling rubbing crusher pair roller to lithium cell material.

Background

The field of mechanical processing has many machines for crushing materials, and the materials comprise powdery food, raw material powder of lithium battery industry and the like. The process of pulverizing is usually divided into primary crushing, fine crushing and superfine crushing. The primary crushing is to break up the larger particles of the raw material into smaller particles that are convenient for further grinding. Originally, two pairs of rollers which are parallel to each other are used, and materials are extruded through rotation, so that preliminary crushing is realized. During use, it is found that if the material is doped with harder particles, such as agglomerated material or other impurities, the material is easy to jam the counter roller and even damage the counter roller.

Preferably, set up a plurality of screw hole on the roll body, broken stake is cylindrical, broken stake afterbody is provided with the screw thread, broken stake screw thread sets up in the screw hole, be provided with two installation faces that are parallel to each other on the periphery wall of broken stake.

Preferably, a cylindrical protection barrel is sleeved outside the roller body, the protection barrel is molded on the roller body through tetrafluoroethylene, and the head of the broken pile is exposed out of the protection barrel.

Preferably, the roller body is cast from cast iron and has a central bore in which the drive shaft is mounted.

Preferably, the head of the broken pile has a chamfer angle of 4mm, and the height of the head of the broken pile is 10-15 mm.

Preferably, the fixing part is provided with a threaded fixing hole penetrating through the fixing part.

The utility model discloses a rubbing crusher pair roller sets up the broken stake of a plurality of on the roll body, rotates the in-process at low-speed, through the extrusion material, realizes broken material. In the use process, the distance between the two pairs of rollers is larger, so that the condition that the pair of rollers are stuck and even damaged can be effectively avoided. Repeated experiments prove that the structure and the material of the broken pile are optimized, and the service life of the pair roller is effectively prolonged.

Detailed Description

The following describes in further detail embodiments of the present invention.

As shown in fig. 1 to 3, a pair roller of a pulverizer of the present invention includes a cylindrical roller body 10. The roll body 10 is cast from cast iron and has a central bore 12 in which a drive shaft (not shown) is mounted. The two ends of the roller body 10 are provided with fixing parts 14 along the axial direction thereof in a protruding manner, and the fixing parts 14 are provided with external threads. Protection plates (not shown) are disposed at both ends of the roller body 10, and the protection plates are connected to the fixing portion 14 through screws for protecting both sides of the roller body 10. At least one of the fastening portions 14 is provided with a threaded fastening hole 16 therethrough, and the roll body 10 can be fastened to the drive shaft by means of screws passing through the fastening hole 16. The roller body 10 is externally sleeved with a cylindrical protection barrel 18, the protection barrel 18 is molded on the roller body 10 by tetrafluoroethylene, the tetrafluoroethylene and cast iron have very high firmness after the tetrafluoroethylene is molded, the tetrafluoroethylene protection barrel 18 has wear resistance, the roller body 10 of a cast iron structure can be protected, the service life of the roller body is prolonged, and the running noise of equipment is also reduced.

The roller body 10 is provided with a plurality of threaded holes (not shown), a plurality of cylindrical crushing piles 20 with threads 28 arranged at the tail end are arranged in the threaded holes, the crushing piles 20 are provided with head portions 22 protruding out of the protective cylinders 18, the head portions 22 are conical, and the outer peripheral wall of each crushing pile 20 is provided with two mounting surfaces 24 which are parallel to each other and are used for forming a clamping surface for a wrench to clamp the crushing piles 20 to rotate the crushing piles 20. This facilitates the installation and replacement of the pile 20.

Further, the crushing piles 20 are made of tungsten carbide and are symmetrically arranged along the circumferential direction of the roller body 10.

Further, the head 22 of the pile 20 has a chamfer 26 of 4mm, the head 22 of the pile 20 being 10-15mm high. Chamfers and heights are good values obtained through practical tests, and can ensure that the service life of the broken pile 20 is longest while the breaking is realized.

The above embodiment is only one embodiment of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
