Abstract
The utility model discloses a roller of a roller screen. The roller includes a roller core and a wear-resisting layer bonded to the outer layer of the roller core, wherein the roller core is made of a metal material, and the wear-resisting layer is made of a polyurethane elastic material. The roller core is made of the metal material, so as to improve the hardness of the roller of the roller screen and prevent the roller from cracking; and the outer wear-resisting layer made of the polyurethane elastic material achieves outstanding anti-tear, wear-resisting and anti-cutting performances, so as to prevent materials from sticking to the roller of the roller screen and achieve high wear resistance of the roller.
Description
Technical field
The utility model relates to a kind of live-roll grizzly roller, is mainly used on the roller type sieving machine.
Background technology
On the green-ball roller type sieving machine that in iron company's pelletizing industry, iron ore roasting technique, uses; Be used to sieve the sieve roller of pelletizing; Ceramic material or the stainless steels of adopting more, the stainless steel sift roller is more durable, but because pelletizing has viscosity; Cause that to be stained with material in the use serious, ceramic roller is run into foreign matter and is stuck in and is prone to cause roller cracked between two rollers; Fracture, scratch often appear in the sieve roller of above-mentioned material in producing use, not wear-resisting, are stained with material, run into hard thing and are prone to phenomenons such as cracked ground, have a strong impact on production.
Summary of the invention
In order to solve the problems of the prior art, the purpose of the utility model provides a kind of high abrasion, is not stained with material, not cracked live-roll grizzly roller.
For achieving the above object, the technological means of the said employing of the utility model is: a kind of live-roll grizzly roller, and comprise roller core and be bonded in the outer field wearing layer of roller core, said roller core adopts metal material, and said wearing layer is selected polyurethane elastomeric materials for use.
Further, the thickness of said wearing layer is 1/3 o'clock of roller core thickness, best results.
The beneficial effect of the utility model is: roller core is selected metal material for use, has improved the hardness of live-roll grizzly roller, makes it can be not cracked; Outer wear layer selects for use polyurethane elastomeric materials to process, and has outstanding anti tear and wear-resisting, cutting resistance ability, makes the live-roll grizzly roller not be stained with material, high abrasion.
Description of drawings
Describe below in conjunction with the technical scheme of accompanying drawing the utility model.
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, roller core, 2, wearing layer.
The specific embodiment
A kind of live-roll grizzly roller as shown in Figure 1 comprises roller core 1 and is bonded in roller core 1 outer field wearing layer 2 that said roller core 1 adopts metal material, and said wearing layer 2 is selected polyurethane elastomeric materials for use.
Further, the thickness of said wearing layer 2 is 1/3 o'clock of roller core 1 thickness, best results.
The metallic roll core outer surface connects firmly through gluing after coating one deck polyurethane elastomeric materials; Have outstanding anti tear and wear-resisting cutting performance; Service life than the long 3-5 of steel rider doubly; Be mainly used in colliery, power plant, coal preparation plant give screening and greater than the final sizing of 13 mm particle size groups and pelletizing plant of iron company make the ball screening, also be used for the screening of other lump materials.
