Abstract
A kind of continuous micron mill that is used for granular material is made up of the rotating cylinder of a big L/D ratio, and this rotating cylinder is divided into several mill storehouses, and wherein the size of the mill amboceptor of Fang Zhiing reduces gradually, and shot-like particle and mill Jie's ratio is also inequality.
Description
The present invention relates to a kind of high yield tubular type micron mill of continuous periodic duty.
The dry type or the wet type grinding that reduce solid granulates shape product size are in production low-cost, high yield, particularly in mining industry and the building industry and the production of expensive, low-yield, in particularly fine chemistry industry, pharmaceuticals industry and the cosmetics industry, one of the most universal production operation.
Above-mentioned back one class industry can be born to obtaining granularity less than 10 microns superfine product required high-energy and high processing cost, yet, under the low situation of workinprocess cost, just can not bear.
On commercial scale, per hour being equal to or greater than, 10 tonnes high yield grinding is to carry out in the tube mill that partial stowage's mill is situated between.This mill is situated between and is made up of impact-resistant, regular solid, and this solid generally is a Metal Ball, but also can be other shapes and kind, as metal cylinder or metal bar, or the stone of rule.
As everyone knows, when the tube mill rotating speed reached certain value, mill was situated between and begins to be subjected to action of centrifugal force.This certain rotating speed is called critical speed, is formulated as:
In the formula, W is the revolutions per minute (r.p.m) of tube mill, and D is the internal diameter (unit: rice) of tube mill.When the rotating speed of tube mill is the about 85% time of its critical speed, the effectiveness maximum that mill is situated between.
The comminution ratio of such grinding machine can surpass 100, but when pulverizer (being reducing of particle size) when being about 25-30, grinding machine most effective.
In general, the high-yield tube grinder of circulation can be produced the abrasive product of particle size distribution between the 0-64 micron continuously, but thinner finished product can not be provided.Thinner if desired product then must use different flour mills, as microballoon grinding machine, compressed air micron mill.Such flour mill output extremely low (being not more than 1000 kilograms/hour) and energy consumption is high, need generally to be used to Size Distribution at the 0-20 micron is sometimes in the production of the ultra micro granularity material of 0-10 micron, in the production as dyestuff, agricultural chemicals and ink.
The present invention adopts a kind of dry type or wet type continuous powder milling technology, and the above-mentioned limitation of known equipment is overcome.This dry type or wet lapping technology can be at the specific yield height, produce particle size under the low situation of energy consumption less than 20 microns abrasive product.

The metal mill of packing in the inside in garden tubular mill storehouse 3 is situated between, as the steel ball rod iron.
To the tail storehouse of discharging micro mist shape product, the size that mill wherein is situated between reduces gradually from the first storehouse of charging.According to the present invention, it is found that when in each mill storehouse, the size of the mill amboceptor of particularly placing is incomplete same but when having certain size to distribute, can obtain best mill efficiency in first storehouse.Because can make the possible collision frequency between abrasive product and the mill Jie reach maximum like this, and the unit kinetic energy that has at least part mill to be situated between is enough to the particle of size maximum is clayed into power.
The Size Distribution that mill is situated between must be relevant with the particle size of charging.The liner plate 6 of trough of belt is housed on the barrel in mill storehouse 3; it not only provides necessary protection to barrel; but also mixed, the reach of grind materials are treated in decision; the mill amboceptor is rotated and rise to the certain height directly related with rotating speed along the wall of trough of belt; fall on the stratum granulosum along a parabolic path then; circulation just makes material obtain grinding so repeatedly.
According to the embodiment of a recommendation of the present invention, rotating cylinder 1 is divided into three cylindric mill storehouses 3, and wherein, middle mill storehouse is longer than two other greatly.
The effect in the first mill storehouse is the size that reduces that part of particle the thickest in the charging, and the major part of grinding operation is carried out in spacious middle mill storehouse, and grinding is then finished in the tail storehouse.
The micro mist product is discharged tubular tail storehouse by the blade of partition panel, is carried in known manner by magazine 7 and goes to store.One of essential part of micron mill of the present invention is a partition panel, and this partition panel both played bulkhead between different mill storehouses, plays product charge level controller again, sees Fig. 2 A and B.
Partition panel is made up of an outer ring 11 and two flat circular sector wallboards 12 and 13 in front.Wherein, outer ring 11 is used for partition panel is fixed to the tubulose barrel, and wallboard 12 and 13 is in the face of adjacent mill storehouse 3, and material is sent between these two wallboards from left to right.
In the wallboard 12 in mill storehouse, upper reaches, there is being annular to comb in close central circular zone and stitching 14, at the seam of then combing near peripheral border circular areas.At the center of partition panel, be provided with a tubaeform member 15, the shape such as the truncated cone, its handle face is towards dirty mill storehouse.In the wallboard 13 in dirty mill storehouse, a center hole is arranged, this hole and the truncated cone 15 coaxial lines are discharged for material.
In the disc space that limits by wallboard 12 and 13, except that the truncated cone 15, also be provided with a series of blades 16.These blades are used for transmitting material between each mill storehouse.According to grinding machine of the present invention, its course of work is basic identical for dry mill process and wet-grinding technology and relative device, and in wet-grinding technology and relative device, solid material is present among the liquid phase with the high-concentration suspension state.
When grinding machine rotates, having forwarded annular in the circular sector part of the low level seam 14 of combing to allows muddy liquid (under the wet-milling situation) or powder (under the dry grinding situation) to pass through, enter by wallboard 12 and 13 and annular element is 11 that surround, the partition panel female parts of blade 16 is wherein arranged from upper reaches Mo Cang, and be accumulated by the direction shown in the arrow at this.The fan-shaped part that contains the turbid liquid that accumulates in this female parts or solid-state powder continues when low level turns to a high position, the turbid liquid or the solid-state powder that are blocked by blade 16 just drop on the truncated cone 15 in the effect of gravity, and the center hole by wallboard 13 enters the dirty mill storehouse that is arranged in Fig. 2 B right side.The truncated cone 15 also can be the butt positive tetrahedron that the regular polygon bottom surface is arranged.
In this respect, should be noted in the discussion above that the needed thruput of grinding machine is usually much smaller than the conveying capacity of blade 16 if the circular sector zone separates each other fully.
By changing the thruput that series of parameters can change grinding machine.These parameters mainly are: number, size and the position of the seam 14 of combing, and particularly wallboard 12 periphery places do not have the width of the seam part of combing; The number of blade 16, shape, size and they are with respect to the conveying capacity of the radial position in bypass slit and the blade that obtains thus.
In an embodiment who selects the superior of the present invention, the tail storehouse of micron mill is to separate by partition panel and the discharge gate that wallboard 12 is housed.Wherein, the nothing of wallboard 12 peripheries is combed the width in seam zone significantly less than the comb width in seam district of the nothing of the wallboard 12 of other partition panel, like this, the charge level of abrasive product is just low, and all surrounded, make the effect of grinding the sieve that has been situated between, prevent the discharge of the particle beyond size range by mill Jie.
