Description

A kind of nodding centrifugal ball mill mechanism and the improvement of installation method

Technical field

The invention belongs to powder body grinding technique field, particularly relate to a kind of nutation movement by machinery and make medium ball, material Obtain the efficient ball milling that limits of nothing " critical speed " or autogenous grinding, the grinding of Semi-Autogenous powder body of high-strength three-dimensional centrifugal force acceleration Equipment.

Background technology

Existing powder body milling apparatus, such as traditional cartridge type ball milling or autogenous grinding, semi-autogenous mill, owing to being limited by " critical speed " System, abrasive media (ball or rod), material can only leave with relatively low acceleration of gravity or let out and be ground material.Equipment Effectively kinetic energy can not be passed to medium and material, so power consumption is the highest.Compared with tradition ball tube mill, nutating centrifugal globe Grinding machine can be considered the ball mill that accelerate in the field of force work much bigger in the heavier field of force.Circular motion is different from nutation movement, weight The field of force is different from accelerating the field of force, thus nutating does not exists " critical speed " therefore can input large energy in unit volume.

Vertical section is in the mill chamber of " ω " shape, spacing, with " α " as inclination angle, with " ε " as maximum eccentricity centered by " o " puts Doing high speed centrifugation oscillating motion, kinetic energy is passed to medium and material by (mill chamber with the earth do not produce relative rotation), make medium and Material obtains bigger three-dimensional centrifugal acceleration, is bigger severity of grind.

Patented technology ZL201010119740.9 announced, finds rigidity dentation spacing ring machine by experiment with analyzing Structure, is difficult to close, causes lubricating difficulties, produces the technological deficiencies such as vibrations in operating；In the vortex used in selecting crude drugs with winnower, wind is mended in circulation Mode, it is impossible to effectively powder body qualified bottom mill chamber is taken out of, there is technological deficiency；Shape and peace for mill chamber wear-resistant liner Dress method also needs to supplement.

The present invention is to solve the deficiency of prior art, it is provided that one overcomes above-mentioned technological deficiency, to mill chamber wear-resistant liner Shape and installation method carry out the novel nutating centrifugal mill supplemented.

Summary of the invention

For solving above-mentioned technological deficiency, the technical solution used in the present invention includes:

1. flexible limit and adjusting apparatus and installation method；

2. wind selection method and the improvement of wind-supplying mouth；

3. mill chamber wear-resistant liner shape and installation method；Three aspects are constituted.

Described flexible limit and adjusting apparatus with installation method be: power input belt wheel and stand the main shaft arranged respectively It is arranged in the leghole on base by lower bearing, thrust bearing, upper bearing (metal) from bottom to up；Main shaft upper end keyed jointing inclined shaft set, tiltedly Installing cross roller bearing on axle sleeve, cross roller bearing horizontal central line, bearing center line intersects at main shaft center line " o " point, bearing center line, main shaft center line form " α " inclination angle.Inner grinding cavity is installed with lower mill chamber even on cross roller bearing top circle Connect, lower mill chamber bottom surface anti-skid design and non-skid rubber ring Structure deformation；Be welded and fixed at column bottom cylindrical on base bung flange with Adjustment circle is spirally connected, and installs non-skid rubber ring in adjusting circle upper surface annular recess, adjusts circle cylindrical along having uniform driving hole, lower end Face has " β " angle domatic；Under the upper surface that on base, layout at least three is uniform has " β " angle in opposite direction with adjusting circle domatic The drift of end face level, drift lower surface and the annular boss sliding contact on base；Advance and retreat screw rod is by oscillating bearing, bearing block It is connected with drift and uniform with advance and retreat pole socket is arranged on the horizontal plane of base upper surface.

Described wind selection method and the improvement of wind-supplying mouth be: the inclined shaft of main shaft upper end keyed jointing puts the decussation rolling of installation Inner grinding cavity is installed on sub-bearing top circle, inner grinding cavity wall has the uniform center line of axial multilayer, radial circumference in " r " inclination angle inclined hole； Inner grinding cavity is connected with lower mill chamber, and lower mill chamber is connected with upper mill chamber；Smooth positive sphere with " o " point as the centre of sphere is arranged at upper mill chamber top, Coordinate with the air inducing ring gap of positive round, with air inducing cushion rubber sliding connection；Positive cone wind scooper, back taper wind-guiding is had in air inducing circle Cover；Feeding screw feed pipe is arranged in air inducing circle, and its running part and hopper are arranged on outside air inducing circle.

Described mill chamber wear-resistant liner shape and installation method be: the wear-resistant liner body being made up of upper and lower wear-resistant liner, is The different in nature cavity that two peripheries coincide with upper and lower mill chamber inner wall size, upper wear-resistant liner is arranged in mill chamber, under wear-resisting in Lining is arranged in lower mill chamber.

Such scheme is used to reach to provide the benefit that:

1. flexible limit and adjusting apparatus and installation method, change the upper and lower spacing ring of rigid teeth ring type of prior art Structure, overcome processing that rigid limit causes, lubricate, many defects such as vibrations, make equipment operation the most steady.Due to flexibility Spacing, adjust circle above rubber ring decussation bearing is toppled power load and play cushioning effect.It is simple to manufacture, eliminates profit The links such as cunning.

2. wind selection method and the improvement of wind-supplying mouth: in the spiral use prior art, circulation is mended wind mode and changed benefit outside chamber into Wind, straight air draught is selected.Save former scheme and such as mend the correlated parts such as wind snail ring, wind-supplying mouth.Overcome prior art wind-supplying mouth position Unreasonable, air-flow " short-circuit " can not reach bottom mill chamber, mends wind not enough, mends the defect that powder body up to standard can not effectively be taken out of by wind. This programme air-flow is unobstructed, and grinding efficiency is high, and the new wind that chamber external air inlet supplements also functions to cooling effect to mill chamber.

The wear-resistant liner shape of mill chamber and installation method, it is intended to solve the abrasion difficult problem that high intensity is ground.This programme by upper, The shaped cavity that the wear-resistant liner body of lower wear-resistant liner composition is two peripheries to coincide with upper and lower mill chamber inner wall size；Interior mill Chamber wear-resistant liner is coated with high-abrasive material for heat or is coated with plastic tube.Wear-resistant liner material may select chromium system, tungsten system, titanium alloy casting Part, it is possible to selective oxidation aluminum, carborundum, zirconium oxide engineering ceramics.
