Abstract
A circular centrifugal grinding mill is upright type arranged by am immobilized barrel body and grinds up the ore with the centrifugal force produced by a roller loop revolving with a rotor disk. The circular centrifugal grinding mill is characterized in that inverted tower stepped upper and lower cylinder lining and the outer edge of the roller loop with the equal height are respectively a corrugated surface and a smooth surface; a silencing shield is vacuumed; the pin shaft of the trailed roller loop is jointed by upper and lower two stages. The utility model has the advantages of fine coarse grinding, low noise (90 db), small size, low energy consumption, high unit volume rate of production, easy dust prevention, etc., and can be widely suitable for raw material production departments of mine smelting, construction material, light chemical industry, etc.
Description
The utility model is a kind of efficient comminution equipment that mining and metallurgy, building materials and some light industry raw material production division are ore and brittle material processing that is widely used in.
The rotating cylinder type ore mill of using for hundred coming year such as the production efficiency of equipments such as ball milling, rod milling of being spread out are low and power consumption is to cause one of high principal element of relevant primary industry processing cost with steel consumption height.The present situation of grinding attachment for a change, the fifties Soviet Union, West Germany and our country all once developed centrifugal ball milling (or rod milling) machine, all owing to unreasonable structure, fail to address the above problem, inventor of the present utility model has developed centrifugal hoop grinding machine (seeing 1980 " mine technology " total 62 phases for details, " development of centrifugal hoop grinding machine and production practices ") again at late nineteen seventies.Though this machine production efficiency height, steel power consumption consumption is lower, but owing to exists feed preparation unit size strict (must less than 25mm), traction to grind the easily broken and feed maldistribution of the bearing pin of ring and the big defectives such as (105d β) of operating noise fails extensively to use in industry.
The purpose of this utility model provides hold concurrently energy, convenient disassembly, reliable, energy consumption steel of a kind of corase grind in small, broken bits and consumes the efficient comminution equipment low, that noise is little.
For achieving the above object, the technical scheme that the utility model adopted is:
Upper and lower tube lining inner chamber is the stairstepping of falling the tower, ripple tooth or smooth etc. special are all adopted according to the ground material granularity requirements in the outer garden of stone roller ring on epimere tube lining internal chamber wall and the respective heights, and smooth cylinder is all adopted in the outer garden of the stone roller ring on bottom tube lining internal chamber wall and the respective heights; Be convenient disassembly, the bearing pin that ring is ground in traction is by upper and lower two sections butt joints; Adopt spline to connect between each rotor disk and vertical pivot; For ore is evenly distributed on the working face, in top cover, add a butt garden tapered sleeve tube; Be evacuated in the silencer cover mezzanine space of top cover and tube lining outside, with isolated noise unofficial biography; Be the unhelpful abrasion of further lowering energy consumption and alleviating the tube lining, on the rotor disk edge, a triangular incision is cut away by each fanning strip lap-joint, card with grind ring contact site, upper and lower end face built-up welding specific alloy, make rotor disk become non-consumption part; Add the recirculated cooling water cover on the bearing block of vertical pivot, bearing running hot problem when grinding high-temperature material to solve.
Structure of the present utility model such as Fig. 1 or shown in Figure 2 mainly comprise five parts such as transmission, rotor, cylindrical shell, support and top cover, now are respectively described below:
(1) running part
Upper shell inner chamber maximum gauge be less than or equal to 800mm small dimension the utility model as shown in Figure 2, by the directly transmission of the belt pulley (1) of body upper; And diameter is greater than the big specification of 800mm, the utility model as shown in Figure 1, by the belt pulley of underpart---bevel gear transmission system (13) transmission.
(2) rotor portion
Rotor is made up of distribution plate (3), vertical pivot (11), rotor disk (9), stone roller ring (4) and (10) bearing pin parts such as (7).
The splined shaft of vertical pivot (11) by cantilever segment in turn gone here and there distribution plate (3) and some rotor disks (9) and dressed up rotor subject, each rotor disk is the alternate fanning strip of convex-concave and takes the knot one, the edge of its lap-joint all is cut into a subtriangular otch, rotor disk thickness is highly the same with the stone roller ring, each adjacent rotors dish forms a neutral gear, in three layers of each neutral gear of corresponding top cylinder lining (5), placing an outer garden respectively is the stone roller ring ripple flank of tooth or shiny surface (4); In each neutral gear of each layer of corresponding doffing lining (8), place a light face respectively and grind ring; The endoporus of above-mentioned each stone roller ring is all being pind down by a pair of bearing pin (7), the other end of bearing pin is inlayed respectively in the hole, garden that is inserted in the corresponding dish of rotor disk up and down edge, at bearing pin and the contact site that grinds ring garden cylinder, rotor disk and stone roller ring end face contact site difference build-up wear-resistant alloy.
(3) shell portion
Shell portion is made up of silencer cover (6), top cylinder lining (5) and doffing lining (8).
Silencer cover (6) is the vacuum interlayer housing that is welded into by steel plate, and its inner chamber tapering is fixing with the tube lining, so silencer cover double as cylindrical shell is used; It is stepped that upper and lower tube lining (5) and (8) inwall are down tower, and each ladder height equates with the height that grinds ring (4) or (10); Top cylinder lining (5) each ladder inwall is the ripple flank of tooth or shiny surface, and each ladder of doffing lining inwall is shiny surface.
(4) top cover and support part
Header field comprises top cover (2) or (12), (15) two critical pieces of butt garden tapered sleeve.Top cover plays a part different again because of the kind of drive is different, the top cover (12) of large-scale machine (shown in the figure one) only plays sealing and mine feeding bucket; The top cover (2) of small-sized machine (shown in the figure two) is except that playing sealing machine chamber and mine feeding bucket effect, and double as supports the support effect of vertical pivot and cylindrical shell; Only type of belt drive special use shown in figure one of support (14), the inside of support have a sealing gear-box, and pedestal is evacuated sandwich shell.
