Description
Technical field
The present invention relates to a kind of Ball-stirring mill being intended to more efficiently various material is ground to higher fineness.The cylindrical shell that this Ball-stirring mill has agitator, inwall is multi-prismatic surface and abrasive media.Described agitator is made up of vertical shaft and the several rectangular plate-like be evenly installed on vertical shaft circumference cylinder or frame-shaped stirring vane, can under the effect of drive unit High Rotation Speed, thus drive abrasive media and constantly abrasive media tangentially dished out, abrasive media strikes on the multi-prismatic surface of cylinder inboard wall subsequently, and there is the active region that rotor is got back in irregular bounce-back, the effect being again subject to rotor enters next circulation.
In whole process, between abrasive media, between abrasive media and rotor, between abrasive media and the multi-prismatic surface of cylinder inboard wall, constantly there is shock, abrasive action mutually.If now add the material that amounts of particles is numerous, above-mentioned shock, abrasive action will make material be subject to grinding cracks solution, become thinner powder.
Technical background
Nineteen twenty-eight klein and Szegvari proposes the general principle of Ball-stirring mill, and in agitator, add natural sand grains, then using artificial abrasive media (porcelain ball, glass marble, steel ball etc.), uses agitator grinding material, thus raised the history of Ball-stirring mill.They complete particulate wet-milling with agitator and spherical medium, for coatings industry, and have set up UP company, specialize in manufacturing and designing and applying of Ball-stirring mill.
Mine office of the nineteen thirty-nine U.S. devises a kind of grinder, for clearing up mineral surfaces before flotation.This grinder is made up of the rotor be arranged in a vertical cylinder and stator, and mineral surfaces is cleared up in the friction produced between particle by the relative motion between rotor and stator, and this device of rear discovery is an effectively fine grinding equipment.Up to the present, various types of agitator (rotor), by extensively open, comprises pin bar type, disc type, spiral etc.; The cartridge type that various forms of mill tube (stator) also by extensively open, comprise column casing formula, bores cartridge type, inwall is provided with pin rod, regular polygon grinding cartridge type etc.; The form of the overall Ball-stirring mill be disclosed has vertical, horizontal etc.
201020562027.7 disclose a kind of regular polygonal stirring-mill grinding cylinder, cross section is adopted to be the sand cylinder of regular polygon, this shape can limit the rotary motion of slip, prevent from slip face forms darker paraboloid of revolution, increase the friction of grinding charge material and sand cylinder inwall, collision probability, the pulverizing of favourable material.
Summary of the invention
Do not cause by force grinding the problems such as rear raw meal particle size fineness is not high, particle size distribution is excessive, capacity usage ratio is on the low side to overcome ectonexine Medium Exchange effect in this type of technology agitator stirring action deficiency existing, the Ball-stirring mill course of work, task of the present invention proposes a solution, in agitator stirring action abundance, the Ball-stirring mill course of work, the effect of ectonexine Medium Exchange is strengthened to utilize this solution to ensure, after mill, raw meal particle size is thinner, particle size distribution is more concentrated, and capacity usage ratio significantly improves.
By the present invention, this task is resolved by a kind of a kind of Ball-stirring mill with feature described in claim 1.Other favourable design can be resolved from dependent claims.
According to solution provided by the present invention be: a kind of agitator of Ball-stirring mill is made up of vertical shaft and the several rectangular plate-like be evenly installed on vertical shaft circumference cylinder or frame-shaped stirring vane, agitator vertical shaft is installed in frame by bearing, and its other end is connected with drive unit.
The cylinder inboard wall of Ball-stirring mill is a multi-prismatic surface, and the rib number of multi-prismatic surface is different from the number of stirring vane and in multiple proportion, to avoid resonance; The abrasive media of right quantity and sphere diameter is filled in a kind of cylindrical shell of New type agitation mill.
During a kind of Ball-stirring mill work, agitator rotates under the effect of drive unit, be installed on several rectangular plate-like on agitator vertical shaft circumference cylinder or frame-shaped stirring vane is stirred abrasive media and constantly abrasive media tangentially dished out, abrasive media is made to strike on the multi-prismatic surface of cylinder inboard wall, angle due to this collision varies in the moment, the bounce-back caused is more irregular, mutually collide between the abrasive media that such collision and bounce-back will aggravate to be in diverse location in cylindrical shell greatly, grinding, now, the material be between abrasive media is subject to this collision, the rapid refinement of abrasive action.
Meanwhile, such collision and bounce-back will greatly promote to be in the abrasive media generation convection current of diverse location in cylindrical shell, and this convection current can play again the effect driving material convection current, make the raw meal particle size after final grinding more even.
