Abstract

The utility model discloses a high-speed machine for crushing, grinding and winnow, suitable for the powder processing in the trades of cement grinding, chemical industries, building materials, ceramics, fire resistant materials, mineral processing, etc. The utility model is characterized in that the complete machine is a vertical type; the three-in-one structural style of crushing, grinding and winnow is adopted. In the crushing part, a common vertical shaft type composes a thick and thin composite crusher. In the grinding part, a pair of plane grinding slices and a pair of involute type grinding slices compose a thick and thin composite grinder. In the winnow part, the wind opening of the lower part through intaking wind is regulated by the wind rate composes a winnower. Powders are selected to enter a dust collector by external wind, and then become the finished product.

Description

High-speed machine for crushing, grinding and winnow

The broken abrasive dust of high speed selection by winnowing end machine belongs to cement machinery.

In to the ball mill transformation process that falls behind, adopt vertical grinding-in pneumatic separator to carry out cement grinding production both at home and abroad.The roller type vertical mill that China was designed in recent years and copied particularly.Though production efficiency has raising, all based on mill.Energy consumption is also bigger.Output can not improve significantly.For this reason, in inquiring into the process of grinding, brainstrust advocates many broken few mills again, based on broken, because fragmentation is promptly fast simply again, like this, just more enhance productivity in the highland, and cut down the consumption of energy in a large number.According to theory of comminution, develop that a kind of energy-efficient fragmentation combines with grinding, the broken abrasive dust of the high speed selection by winnowing end machine that save operation, reduces manpower is fully feasible.

The purpose of this utility model, be to provide one simple in structure, volume is little, power is little, the broken abrasive dust of the high high speed selection by winnowing of abrasive dust efficient end machine, so that the grinding processing of cement sectors and itself and chemical industry, electric power, mining industry is based on broken, many broken few mills, cut down the consumption of energy, improve output.

Task of the present utility model realizes by following approach.

In theory of comminution, except that the hammer crushing of speaking of, also talk about the grinding of the suitable thin material of plain grinding, and abrasiveness is better, so the utility model adopts fragmentation and grinding, selection by winnowing structure combining form.This machine mainly divides fragmentation, grinding, selection by winnowing three parts to form; Complete machine is vertical state, broken segment is contained in top, bear by the compound hammer mill of common vertical shaft type, divide thin broken district and ultra-fine broken district in the composite breaking machine, it is multiple broken that the broken back interior high speed sieve of machine is selected from row, means of abrasion is by being contained in disintegrating machine vertical shaft bottom, and a pair of involute shape correct grinding band of the pair of planar rough lapping band on the unified thus traffic cycle that drives and its periphery is born; The powder selecting part branch selects powder by the air blade that is contained in the rotating disk bottom by the on-stream pectinid that makes progress voluntarily of air intake tube; The air quantity size is by the control of air quantity mediation board, and the powder of selecting enters dust arrester through defeated powder tube and just becomes product.

The concrete structure of utility model is provided by following examples and accompanying drawing thereof.

Accompanying drawing is the general assembly schematic diagram of the broken abrasive dust of the utility model high speed selection by winnowing end machine.

Can be described with reference to the accompanying drawings concrete structure of the present utility model and operation principle below.

This machine comprise a charging aperture 2, vertical shaft 3, vertical compound hammer mill 4, thin broken district 5, ultra-fine broken district 5 ', conical screen 6, shell 7, conical shell 8, slag notch 9, adjust nut 10, traffic cycle 11, air quantity mediation board 12, air intake tube 14, air blade 15, back cover 17, wind deflector 19, separator 22, allocate abrasive sheet 24, moving flat abrasive sheet 25, decide involute shape abrasive sheet 26, move involute shape abrasive sheet 27, thrust spring 28, fine-tuning nut 29, chassis 30.

Its operation principle is: when this machine work, drive vertical shaft 3 rotations by power, each tumbler of complete machine is started working, entered thin broken district 5 by arrow 1 through charging aperture 2 by grinding material, after dropping to ultra-fine broken district 5 ' interior further ultra-fine the breaking of separating up and down after thin the breaking, drop to high speed screening in the conical screen 6 that drives by vertical shaft 3, after fines sieves down by dotted line, coarse fodder in sieve along the direction of arrow by action of centrifugal force above awl sieve edge flies to, return ultra-fine broken district 5 ' carry out breaking again; Fallen on the traffic cycle 11 that drives by vertical shaft 3 by the thin material that sifted out, fall along warp-wise by being contained in allocating abrasive sheet 24, be contained in the rough lapping band that the moving flat abrasive sheet 25 on the traffic cycle 11 forms and carry out rough lapping on the chassis 30 through centrifugal action.Material after slightly grinding continues to fall out to its periphery by being contained in deciding involute shape abrasive sheet 26, be contained in the smooth grinding band that the moving involute shape abrasive sheet 27 on the traffic cycle 11 forms and carry out smooth grinding on the chassis 30; And ura-rate goes out.Be the state of descending slowly and lightly by arrow 20.At this moment, the air blade 15 that is equipped with by traffic cycle 11 top and the bottom by front 13 through air intake tube 14 is pressed arrow 18 through wind deflector 19 pectinid upwards.Finished product is just gone out through separator 22 along arrow 21 and is delivered to dust arrester; Behind control of dust, just become finished product.The air quantity size is finished by air quantity mediation board 12, also can join extraneous air inducing, and thick slag leaves down, falls to 8 of conical shells through discharging opening 9 by arrow 16 by the through hole on the back cover 17, drops to the broken again mill of return mechanism by arrow 31.

Nut 10 is adjust to grind the band fit-up gap, and the thickness of grinding is in operation by fine-tuning nut 29 and finely tunes, and thrust spring 28 is to promote decide the pressure of abrasive sheet and floating to move usefulness.

The utility model is compared with existing flour mill, have simple in structure, power is little, volume is little, wear extent is little, small accommodation area, cost are low, save characteristics such as operation and manpower, and be specially adapted to the cement plant newly-built, enlarging, update and the powder processing of other ore dressing industry, chemical industry.

The applicant thinks, realizes that best way of the present utility model is to manufacture special equipment, changes existing ball mill.
