CN2134240Y - Roller sizer - Google Patents

Abstract

The utility model discloses a new-style roller sizer which is provided with a plurality of screening transportation rollers 3 with-shaped cross sections in a parallel way in a sizer housing 2; the screening transportation rollers 3 take the homodromous and synchronous movements driven by a motor 9 through a chain sprocket 6, a chain 7 and a speed reducer 8. The utility model completes the screening work through using the gap when each roller is worked. The utility model has the advantages of low running speed, small dust, little abrasion, low noise, small volume, high strength and long service life. The utility model can be widely used for the screening work of cement and the breaking process in other industries and the material feeding prescreening of a large block of ore. Besides, the utility model is the replaced product of a packaging machine rotating screen in a closed-circuit crushing system and a cement plant.

Description

Roller sizer

The utility model is a kind of new-type screening plant.

Powder and granule shape material needs screening operation, all adopts vibratory sieve or roto-siofter at present.The former vibrates greatly, noise is big, the sieve plate quick abrasion, and latter's volume is big, and investment is big, and dust is big.

The purpose of this utility model is that a kind of simple and practical roller type sifting equipment is provided.

The purpose of this utility model is to realize like this, in casing 2, the screening conveying roller 3 of the many ellipse gardens of parallel installation shape section, and make its ellipse garden shape major axis orthogonal and certain interval arranged, again by the outer sprocket wheel 6 of casing, by chain 7, reductor 8 links to each other with motor 9, respectively sieves conveying roller and is synchronized with the movement by equidirectional thereby make, and utilizes the gap of each roller, in promotion and convey materials, finish screening operation.

The concrete structure of utility model is provided by following examples and attached Fig. 1 and 2.

Fig. 1 is the plane of this equipment, and Fig. 2 is the elevation of this equipment.

This equipment is made up of charging aperture 1, casing 2, fine powder discharging opening 4, coarse grain discharging opening 5 and ellipse garden shape section roller 3, sprocket wheel 6, chain 7, reductor 8 and motor 9.The control screen size is played in the gap that is installed in parallel between the roller 3 in the casing.By reductor 8 and chain 7, drive the sprocket wheel 6 that links to each other with roller 3, by motor 9 to realize the run-in synchronism in the same way of each roller.When material enters in the casing by feeding mouth 1, by the clockwise roller 3 of running, promote the material reach, the fines discharge port 4 that bleeds of the gap when small particles material moves by roller, and coarse fodder is pushed to discharge port 5 by roller.

This equipment speed of service is low, dust is little, wearing and tearing are few, noise is low, and volume is little, simultaneously roller intensity height, be not only applicable to the screening of granule, granular material, and be applicable to and the screening feeding operation of lump ore can be widely used in the screening operation in cement and other industry crushing process that the feeding of lump ore sieves the substitute products of the packing machine roto-siofter in closed circuit crushing system and the cement plant in advance.

Claims (1)

1, roller type sieving machine, it is characterized in that, in casing 2, the screening conveying roller 3 of the many ellipse gardens of parallel installation shape section, and make its ellipse garden shape major axis mutually vertical and certain interval arranged, by the outer sprocket wheel 6 of casing, link to each other again, respectively sieve conveying roller and be synchronized with the movement by equidirectional thereby make by chain 7, reductor 8 and motor 9.
