Abstract
The invention discloses a kind of crushing mill of anode material of lithium battery, including movable grinding disc, fixed millstone and material casting plate, fixed millstone center is provided with circular charging hole, and the gap that movable grinding disc center is provided between the mounting hole that it is mounted on rotor mill, two mills is manually adjustable.Disk medial surface circular arc portion is uniformly distributed groove, and groove radially distributes；Upper lower millstone medial surface flat is provided with the double wedge that annular spread is engaged, and disk body material is Si3N4.The mill material that the present invention is selected is Si3N4, and his hardness is big, fusing point is high, chemical stability good, it is to avoid the chemical contamination problem of lithium battery material, and movable grinding disc has the hardened structure of material casting, drives all materials in processing cavity fully to be crushed；The double wedge at mill edge adds milling area so that material can be crushed more fully.
Description
Technical field：
Present invention design pulverizer technical field, particularly belongs to disintegrating apparatus mill.
Background technology：
In industries such as chemical industry, medicine, mining industry, cosmetics, pigment, electronics, there is substantial amounts of material equipment to be comminuted every year
Working process.Such as lithium ion battery, in order that its capacitance is high, cyclic reversibility is good, resource utilization is high, then to his positive pole
Material needs to accomplish that small particle diameter, narrow particle size distribution, granule-morphology are similar.In departments such as glass industry, powder metallurgy, also need thing
Material is crushed to the granularity of next step job requirements, so as to further processing, and existing disintegrating apparatus is mostly using mechanical punching
Break up broken and air-flowing type to crush, the grain diameter of crushing is big, high energy consumption, with certain limitation.In addition, lithium battery anode
Material is easy to by metallic pollution, is made of metal the most of disintegrating apparatus used now more, and this leverages lithium electricity
The performance of pond positive electrode, we are badly in need of finding out the disintegrating apparatus mill for being more suitable for anode material of lithium battery.
The content of the invention：
The technical problem to be solved in the present invention is：Movable grinding disc can drive the material of all entrance processing cavitys to carry out abundant powder
It is broken；Grindability is improved, more fine-grained comminuting matter is obtained；Prevent metallic pollution
The technical solution adopted by the present invention is as follows：Described device includes fixed millstone and fixed millstone, working face by fixed millstone and
Movable grinding disc is constituted, and fixed millstone center is provided with circular charging hole, and movable grinding disc center is provided with the installation that it is mounted on rotor mill
Hole.Mill inside cross-sectional is arc-shaped, and more flat closer to edge, the arc surface between movable grinding disc and fixed millstone is collectively forming one
Individual materiel machining chamber, the gap that movable grinding disc center is equipped between material casting plate, two mills is manually adjustable.Disk medial surface arc sections
Divide and be uniformly distributed groove, groove radially distributes；Upper lower millstone medial surface flat is provided with the double wedge that annular spread is engaged,
Disk body material is Si3N4。
It is further characterized by：The center of the groove in increased radioactivity is overlapped with the disk body center of circle；In described disk body
Side edge portions do Wear-resistant Treatment；The tooth of the double wedge of the annular spread is high identical with minimum working gap；The material casting plate
Structure be uniform-distribution with three to six perpendicular to face of cylinder modification of right-angled triangle plate for cylindrical outer side, material casting plate is rotated with movable grinding disc
And rotate.
Compared with prior art, the advantage of the invention is that：Gap can adjust between movable grinding disc and fixed millstone, and this is to material
Screening effect is served, energy consumption is reduce further；Mill material is Si3N4, it is a kind of high-temperature ceramic materials, his hardness is big,
Fusing point is high, chemical stability is good, it is to avoid the chemical contamination problem of lithium battery material；Movable grinding disc has the hardened structure of material casting, drives
All materials are fully crushed in processing cavity；The double wedge at mill edge adds milling area so that material can be obtained more
Sufficiently crush.
Brief description of the drawings
Fig. 1 is cross section structure diagram of the invention
Fig. 2 is movable grinding disc top view schematic diagram of the invention
Embodiment
Referring to accompanying drawing, the mill of disintegrating apparatus, including bottom movable grinding disc 1 and top fixed millstone 2, fixed millstone 2 passes through
It is bolted to above terminal pad 4；6 be material casting plate, is connected on the output shaft 7 of drive device；During crushing, material is from charging aperture
5 add, under gravity into materiel machining chamber 3, and under the collective effect of centrifugal force and material casting plate 6, material is to mill
Border movement, and crushed in the presence of shearing force, finally discharged in the gap between mill.Disk body 1,2 materials are
Si3N4；Overlapped in the center of the groove of increased radioactivity with the disk body center of circle；Do wear-resisting place in described disk body medial surface marginal portion
Reason.
