Description
Technical field
The present invention relates to a kind of grate ball mill and ball mill grate.
Background technology
Ball mill utilizes steel ball to carry out ore grinding as crushing medium, be in the industrial department such as ore dressing and metallurgy the most generally,
General milling equipment, grate ball mill is mainly used in 1 section of ore dressing plant ore grinding, is characterized in forcing ore discharge, can obtain higher
Disposal ability；
The Main Function of grate has: 1) realize ore mill forces ore discharge (low-level ore discharge), and mineral aggregate turnover is fast, overground
Gently, be conducive to improving grinding capacity；2) the grid hole width of grate gradually expands (trapezoidal) to ore discharge direction, can prevent ore pulp
Water conservancy diversion and the blocking of bulk ore particle；3) play sieving actoion, stop bulk mineral aggregate and the medium ground to be discharged.
The defect that tradition grate ball mill designs due to grate structure and center liner, long occur that center liner falls
Falling, service life is short, use production to be forced to stop the problems such as maintenance, has had a strong impact on the normal production in ore dressing plant, and due to lattice
Sub-aperture concentric arrangement, ore pulp flows along grid, and grid hole serious wear, ore pulp easily refluxes；The radiation arrangement of grid hole, ore particle is logical
Cross grate moment centrifugalization, be displaced outwardly along hole, easily cause blocking, although these 2 kinds of grid holes serve grate
The effect in hole, but ore discharge efficiency and the serviceability of ball mill are caused and have a strong impact on by its shortcoming.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, it is provided that a kind of grinding capacity that improves, guarantor
Card in ball mill operation process firmly, do not fall off, and just face bolt because of a kind of lattice loosened by pulsating stress or rupture
Subtype ball mill and ball mill grate.
The technical solution adopted for the present invention to solve the technical problems is: a kind of grate ball mill and ball mill grid
Plate, has barrel and reductor, and described reductor one end is connected with motor by shaft coupling I, and its other end is by connection
Axial organ II is connected with small transmission gear, and small transmission gear is connected with the big swiveling gear being located on quill shaft by sprocket wheel, in
Empty axle is provided with barrel, and one end of barrel is connected with main shaft bearing portion, and main shaft bearing portion is connected with feed portion, barrel and feed
Place in opposite direction of portion is provided with discharging portion；
Being inlaid with abrasion-proof backing block on described barrel inwall, quill shaft is provided with some grates, grate includes
Outer ring liner plate and inner ring liner plate, described outer ring liner plate be shaped as sector, its surface is provided with the grate hole of some oblique arrangement, institute
The upper end stating inner ring liner plate is provided with the grate hole of some oblique arrangement, its lower end part blank liner plate, and the side of grate sets
There is the ear block fixing by screw.
Further, described outer ring liner plate and inner ring lining material use the wear-resistant white iron containing metals such as manganese, chromium, nickel
Material is made, its matrix be martensite and by the Hard Inclusion of a large amount of Dispersed precipitate to improve wearability, with the addition of certain simultaneously
The element strengthening matrixes such as Mo, W, V and Ni.
Further, in described quill shaft, stud with wear-resistant liner, and tubaeform blade is made in one end.
Further, the width in described grate hole is 7-20mm, and it is preferably 7-8mm.
The invention has the beneficial effects as follows, the raising grinding capacity of the present invention, it is ensured that in ball mill operation process firmly, no
Coming off, and just face bolt is because being loosened by pulsating stress or rupturing, service life is long, improves work efficiency, weares and teares in grid hole
Relatively low, it is not likely to produce ore pulp backflow phenomenon, is not easily blocked, improve ore discharge efficiency and the serviceability of ball mill.
