Description
The utility model relates to a kind of with the reducing mechanism of rotary collision mode with material pulverizing and powder process.
With the solid material fragmentation and/or the powder process of bulk, be all to need in daily life and the many industrial production field.Present common equipment has grinder, roller mill, outstanding grinding machine, vibrating mill, fan-type grinding machine, ball mill, rod mill, tube mill, hammering grinding machine and Raymond mill etc., wherein most popular is ball mill and tube mill, and the latter then is a kind of variations of ball mill.A common drawback of these equipment is that moving component is too heavy, has caused high energy consumption and poor efficiency, and its fineness of powder of making is the highest also only reaches about 1500 orders, and thinner powder often need lean on grading and regrinding, has caused higher energy consumption.
The purpose of this utility model is to provide a kind of simple in structure at above-mentioned situation, and energy consumption is lower, but and the reducing mechanism of the rotary collision formula of the higher fine-powder product of production fineness.
The structure of rotary collision reducing mechanism of the present utility model is, is provided with the horizontal rotating disc structure that can rotate around the longitudinal axis around in Feng Bi the crushing chamber, and its support face is provided with 4～10 and is the vertical guide frame of radially arranging.Crushing chamber is provided with some and this horizontal rotating disc structure successively continuously and maintains the gap and be the impact baffle plate of tangent shape with its rotation round in the position that adapts with the horizontal rotating disc structure.Be provided with the wind pushing mechanism that upwards to blow under this horizontal rotating disc structure in the crushing chamber; The top of crushing chamber is provided with the air draft mechanism of pump drainage wind outside crushing chamber through exhaust outlet.Position between horizontal rotating disc structure and exhaust outlet be provided be opened on respectively outside the crushing chamber and horizontal rotating disc structure support face above feeding structure.This vertical guide frame can be arranged on the whole support face of horizontal rotating disc structure, nearly peripheral region that also can support face only disposed thereon, its effect is to make to enter and fall within material on the horizontal rotating disc support face through feeding structure and doing under the centrifugal action of high speed rotary turnplate at a high speed to the motion of dish periphery, after this vertical guide frame stops, material can be thrown out of along the tangential direction that rotatablely moves, but under the guiding of this guide frame, radially throw away rotating disk, vertically rush at impact baffle plate at a high speed and collide.Analyze as can be known as calculated, its collision impact power is extremely huge.For example, when two blocks of each heavy 1 kilogram materials clashed into mutually with the speed of 90 meter per seconds, with the material difference of material, its mutual impact can reach tens of tons to tons up to a hundred.So huge impact force is self-evident to the degree of grinding that material can form.Through test, this device of the present utility model to many material grinding and powder process, especially to the grinding of ultrahard material, can be ground into the dust smalls of diameter below 5 microns with the material about Mohs' hardness 9 degree applicable to multiple industry at an easy rate.Once having with waste and old bolt, nut etc. is that raw material is pulverized test with this pulverizer of the present utility model, and only a few minutes just can be ground into it fineness and reach 2000 purpose smalls.On the comminuting matter behind the impact can be rebounded rotating disk, and then thrown away at a high speed, and so carried out impact repeatedly repeatedly, pulverized carefullyyer time by time.Because it is necessary between this rotating disk and impact baffle plate, and must remain with same crack, for prevent that material from falling and stop up at this gap location in carrying out the impact process, the wind pushing mechanism that makes progress that this rotating disk below is provided with and the air draft mechanism of crushing chamber top are necessary, and its formed air-flow that makes progress can play the support effect that stops badly to fall.Simultaneously, this air-flow that makes progress can also be taken out of from exhaust outlet reaching the dust smalls that smashing fineness requires, collects and forms final products.
With 10 tons/hour pulverizing processing capacities is example, with above-mentioned reducing mechanism of the present utility model and adopt fan-type grinding machine that impeller high speed impact material pulverizes, adopt a large amount of steel balls bumps and the ball mill that grinds, relying on the centrifugal action of grinding roller to open can be referring to table 1 than the result of test to compress that Raymond mill that bull ring carries out crush and grind to material opposes.The result of this contrast test can know and demonstrate, because the moving component weight of the utility model device greatly alleviates, so comparable other the similar flour mill of energy consumption reduces by 28～50%, and the repair and replacement of easily worn part are easy, and maintenance cost also reduces significantly.Therefore when reducing mechanism of the present utility model is applied to cement grinding, instead of ball mill and tube mill fully, but also the cement tuberculosis that it can't be able to be handled is worn into fine solid particle shape smalls like a cork, the Extra High Strength cement of production more than No. 1625; Be applied to the thermal power generation field, the colm and the colliery powder that difficulty can be burnt difficult mill are broken into corresponding superfine powder, help catching fire and fully burning, have remarkable energy saving effect and economic benefit; Be applied to grinding, after slag, the steel-making slag powder that ball mill can't be able to be handled is broken into smalls, is higher than the aggregate of annotating steel as production hardness and uses industrial slag, slag; In addition, in metal smelt,, all extensive applicability can be arranged at numerous areas such as construction material, coating, filler, refractory material, glass, ceramic material, fine chemistry industry, medical industries to the pulverizing of multiple ores such as metallic ore, rare earth element ore.
Below foregoing of the present utility model is described further with example shown in the drawings.But this should be interpreted as that the scope of the above-mentioned theme of the utility model only limits to following example.
