Abstract

The utility model discloses a multilayer screen, composed of an upper screen, a middle screen, a lower screen, a sieve pore A, a sieve pore B and a sieve pore C, wherein the dimension of the sieve pore A of the upper screen is more than or equal to 28*30mm, the dimension of the sieve pore B of the middle screen is more than or equal to 18*32mm, and the dimension of the sieve pore C of the lower screen is less than or equal to 10*34mm. The screens are interwoven and welded by steel reinforcements, and surfaces of the screens are formed by mixing synthetic size added with rubber compound ingredients. The multilayer screen disclosed by the utility model has the advantages of light weight, high abrasion resistance, low noise in operation, high efficiency and long service life.

Description

A kind of multilayer screen cloth

Technical field

The utility model belongs to the vibration screening machinery field, mainly relates to the multi-deck screen net vibrating screen of higher disposal ability and screening efficiency.

Background technology

The classification of mineral grain generally is to be accomplished by vibratory sieve, is multilayer and need the screen cloth of the used vibratory sieve of material of multiple fractionation.Because the number of plies of screen cloth that vibratory sieve adopts is relevant with the granularity requirements of stock grading, so how much a stage material of the routine maximum of accounting has a direct relation in the disposal ability of vibratory sieve and the material composition.Existing multilayer vibratory sieve is in operation, above the more one deck screen cloth of material, and windrow and putty easily.Thicker material moves on screen cloth, has directly influenced the disposal ability and the screening efficiency of vibratory sieve.

The utility model content

In order to overcome the defective of above-mentioned prior art, the utility model provides a kind of multilayer screen cloth, and described multilayer screen cloth can effectively improve the screening efficiency of vibratory sieve lower screen.

The utility model is realized through following scheme; A kind of multilayer screen cloth; Form by upper strata screen cloth, middle level screen cloth, lower screen, sieve aperture A, sieve aperture B, sieve aperture C; The sieve aperture A size of said upper strata screen cloth is made as>=28x30mm, and the sieve aperture B size of middle level screen cloth is made as>=18x32mm, and the sieve aperture C size of lower screen is made as≤10x34mm.

Said screen cloth is by the reinforcing bar welding that interweaves, and the surface all adopts synthetic size to add that rubber chemicals are mixing to form, and makes rubber and screen cloth that high strength bond property arranged, and makes Rubber screen that good draftability arranged at work, guarantees that rubber can not break away from.

The utility model is compared the outstanding advantage of prior art: the screen size that reduces upper strata screen cloth, middle level screen cloth, lower screen is crossed by described multi-deck screen Netcom; Make not only that the ore grain size that drops down onto lower screen is corresponding to be reduced; And effectively raise the screening efficiency of vibratory sieve lower screen, thereby impelled ore crusher to fully play maximal efficiency greatly; The utility model prolonged the service life of vibration screen, and wire side is smooth, tensile strength is good because the use elastomeric material has improved the endurance life of screen cloth, and plasticity is big, has reduced working strength of workers and production cost.

Description of drawings

Fig. 1 is the structural representation of a kind of multilayer screen cloth of the utility model;

Wherein: 1-upper strata screen cloth; 2-sieve aperture A; 3-middle level screen cloth; 4-sieve aperture B; The 5-lower screen; 6-sieve aperture C.

The specific embodiment

As shown in Figure 1: a kind of multilayer screen cloth; Form by upper strata screen cloth 1, middle level screen cloth 3, lower screen 5, sieve aperture A2, sieve aperture B4, sieve aperture C6; The sieve aperture A2 size of said upper strata screen cloth 1 is made as>=28x30mm; The sieve aperture B4 size of middle level screen cloth 3 is made as>=18x32mm, and the sieve aperture C6 size of lower screen 5 is made as≤10x34mm.

In the time of in ore gets into disintegrating machine, owing to reduced the sieve aperture A2 size of upper strata screen cloth 1, thus effectively increased ore upper strata internal circulating load in disintegrating machine, make ore that the longer pulverizing time arranged; The sieve aperture B4 that utilizes middle level screen cloth 3 simultaneously further effectively impels disintegrating machine to give full play to performance as the buffer zone, reduces the sieve aperture C6 of lower screen 5 at last, has realized how broken few mill, and the screening efficiency of lower screen 3 is improved fully.

What should explain at last is: carefully do not state part in the above content for prior art, do not state so run business into particular one, said embodiment is the described technical scheme of unrestricted the utility model also in order to explanation the utility model only; Therefore, although this specification has carried out detailed explanation to the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of the spirit and the scope of the utility model, all should be encompassed in the claim scope of the utility model.

Claims

1. multilayer screen cloth; Form by upper strata screen cloth, middle level screen cloth, lower screen, sieve aperture A, sieve aperture B, sieve aperture C; It is characterized in that being: the sieve aperture A size of said upper strata screen cloth is made as>=28x30mm; The sieve aperture B size of middle level screen cloth is made as>=18x32mm, and the sieve aperture C size of lower screen is made as≤10x34mm.
