Description

A kind of cartridge type roller is milled

The utility model belongs to a kind of grinding processing unit (plant) of solid material.

In industrial production, often need be processed into fine powdered to granular solid material, as in the manufacture of cement lime stone and the clinker that is fired into being clayed into power; The fire coal that uses in the power plant is worn into coal dust etc.The most frequently used grinding machine is a ball mill at present, it can be levigate to 1-100 μ m with the solid material that is of a size of several centimetres, but the effective rate of utilization of ball mill energy in grinding processing only has 2-5%, therefore say, used ball mill energy consumption is than higher, and equipment is huger, and grinding adds man-hour, noise is big especially, and working environment is more abominable.For this reason, occurred multiple novel grinding process equipment in recent years again, it is exactly wherein a kind of that the cartridge type roller is milled.The structure that the cartridge type roller is milled is: in same revolving drum, one or several grinding rollers are installed, are relied on the wear ring of revolving drum inwall and the extruding between grinding roller to come grinding material.This milling equipment is compared with ball mill, can saves energy more than 35%, and abrasive body is worn few.But this roller is milled the imperfection part is arranged also, mainly be material by grinding after, the thickness powder mixes, and needs the special-purpose classification choosing of preparation to divide device, makes grinding process become complicated, the investment of equipment is also bigger.

The purpose of this utility model is to provide a kind of mill efficiency height, energy consumption is low, equipment investment is few combination cartridge type roller to mill.

The purpose of this utility model is to realize like this.It comprises one through the rack-mounted cylinder of support roller, grinding roller is installed in cylinder and is separately installed with left backplate and right backplate in these cylinder both sides, have charging aperture on the wherein left backplate, and the roller that the power set formation that drives the cylinder rotation is installed on frame is milled, its technical essential is that the right-hand member at cylinder is installed with a rotary screen, its right backplate is fixed on the frame of rotary screen right-hand member, on right backplate, be installed with simultaneously the guard ring of cylinder, the downside of this guard ring has discharging opening, so that the material powder that rotary screen is sieved out takes out.

Because this cartridge type roller is milled and added a rotary screen on the structure that conventional roll is milled, it can be easily sieves out with the fine powder of grinding in time, being convenient to grinding roller and cylinder rolls effectively, pulverizes oarse-grained material, to improve the operating efficiency that this roller is milled, reduce fruitless labour.Bulky grain to screening is come out along with the rotation of rotary screen, turns back to cylinder again and grinds, and also can accelerate the grinding efficiency to solid particle.Because this roller is milled and can be saved original special-purpose classification, lifting device, and the investment of equipment can be reduced widely.The utility model combines with the ingenious of wearproof roller through rotary screen, makes the structure of equipment more reasonable.Energy consumption also correspondingly reduces.

Fig. 1 is a structure principle chart of the present utility model;

Fig. 2 is the A-A cutaway view of Fig. 1.

Below in conjunction with accompanying drawing the utility model is described in detail.

Frame 3 of the present utility model is bases of this equipment, and the power set that its support roller 4, drive cylinder rotate all are fixedly mounted on the frame 3.The rotating shaft at grinding roller 16 two ends also is installed on the frame 3 through bearing.Its cylinder 11 is made up of cylindrical shell 8 and wear ring 9, and the fixed outside of cylindrical shell 8 is equipped with entrusts 7 and gear wheel 10, and cylinder 11 is installed on the support roller 4 through entrusting on the cylindrical shells 8.The power set that drive cylinder 11 rotations generally drive driving gear 2 by motor 1 through decelerator and constitute, and gear wheel 10 engagements on driving gear 2 and the cylinder 11 drive cylinder 11 rotations.Grinding roller 16 is installed in the cylinder 11, with the wear ring 9 formation milling mechanisms in the cylinder 11.There is left backplate 5 in the left side of cylinder 11, and is provided with charging aperture 6, so that reinforced in cylinder 11.The left end of cylinder 11 is installed with a rotary screen 12, rotates together with cylinder 11, and sieve material in rotation process.The right-hand member of rotary screen 12 is equipped with right backplate 13, in case material flows out at right-hand member.On right backplate 13, also be installed with a guard ring 18, have discharging opening 17 below the guard ring 18, so that the material fine powder that will be sized is out taken away.Here said left and right backplate all is fixedly installed on the frame 3.

In order to make the big material particles that is sized out flow back in the cylinder in time, inner surface at rotary screen 12 is installed with stock guide 14, stock guide 14 is a spirality, along with the rolling of rotary screen 12, will back in the cylinder 11 by the material that stays after the screening.
