4. adopt the feed back perching knife, improved percentage of damage greatly, thoroughly solved the leakage material phenomenon of autogenous mill.
Concrete structure of the present utility model is provided by the following drawings and embodiment:
Fig. 1 does not have medium fine mill structure schematic diagram for cyclone type
(1) vertical machine, (2) step, (3) cyclone disk rotor, (4) annular is wear-resistant, (5) impact block, (6) wind feeding blades, (7) feed back perching knife, (8) annular hyperboloid wearing plate, facing plate, (9) the strong autogenous grinding cover of hyperboloid, (10) protect stream cover, (11) charging aperture, (12) one-level separating sieve, (13) interior feedback outlet, (14) secondary classifying screen, (15) upper and lower bearing block, (16) separating sieve motor, (17) discharging opening, (18) support, (19) isolating cylinder, (20) interior feed back cover, (21) annular abrasion road.
Embodiment:
Below by embodiment the utility model is specifically described; be necessary to be pointed out that at this following examples only are used for the utility model is further specified; can not be interpreted as the restriction to the utility model protection domain, the person skilled in art can make some non-intrinsically safes to the utility model according to foregoing and improve and adjust.
The structure that cyclone type does not have the medium fine grinding machine is to be provided with discharging opening (17) in the body upper end, the shaft extension end of separating sieve motor (16) connects by shaft coupling, under bearing block (15), and connect, drive one, secondary separating sieve (12), (14), cover (20) and interior feedback outlet (13) reflux in the separating sieve periphery is provided with, have jet lip limit at interior feedback outlet, be provided with isolating cylinder (19) in the taper cavity in stage casing, isolating cylinder is fixed in the middle of the strong autogenous grinding cover of annular hyperboloid (9), the cavity hypomere is provided with annular hyperboloid wearing plate, facing plate (8), the charge level of meeting at strong autogenous grinding cover of hyperboloid and wearing plate, facing plate is equipped with hemispherical protruding spheroid or cone, and be arranged by spiral, their annular surface is the curve that is similar to R=100～300mm, constitute strong autogenous grinding district, stage casing and fracture area, form annular abrasion road (21), protect stream cover (10) the strong material flow of height is separated.The lower end is cyclone disk rotor (3) again, the charge level of meeting of cyclone disk is provided with annular wear-resistant (4) and impact block (5), and the back side of cyclone disk is provided with wind feeding blades (6), and the blade outside is provided with feed back perching knife (7), rotating shaft connects with main motor (1) by bearing block (2), and complete machine is contained on the support (18).
The utility model is achieved in that 2～5cm
3Pellet is sent into charging aperture (11), with 0.3～0.5 Kilograms Per Second input, material drops on the cyclone disk of rotation at a high speed, quickening the back is hit by impact block (5) with 80～100 meter per second speed, after hyperboloid wearing plate, facing plate (8) bump, fragmentation, the material that resilience material and cyclone disk launch once more, and the material that rotates back in the impelling of material shovel cutter clashes to hitting, fixedly high speed circulation is material bed simultaneously to have formed one in the milled-in path (21) of annular surface, has improved material impact grinding rate on the one hand; On the other hand wearing plate, facing plate has been played the protective effect that reduces brinelling.On annular surface, the pellet that falls again by high velocity air and rotate back to the impelling of material shovel cutter get on the annulation materials flow to hitting, material flow is gone in the bi-curved strong autogenous grinding cover (9) by precession in the high-speed rotational of 30～45 meter per seconds that cyclone disk and wind feeding blades produced, carry out strong autogenous grinding, promptly produce desirable autogenous grinding effect.The effect of isolating cylinder (19) is primary election, the powder of 21～24 μ m falls back on the parabolic dish, enter the strong mill of circulation again, first order separating sieve is for falling bell or straight tubular, every sieve plate spacing is between 25～45mm, diameter is φ 600～900mm, 400～1500 rev/mins of rotating speeds, material after eddy flow will carefully select in the classification chamber is sent into second level separating sieve, and the secondary separating sieve is a plane annular, radial equipartition sieve plate, and spacing is between 20～38mm, diameter is φ 900～1200mm, rotating speed is 400～1500 rev/mins, can be the product that accounts for total output 70% of 5～2 μ m of 15 μ m cut-out by powder, is discharged by discharging opening.Interior feed back cover (20) that powder that can not be by the I and II separating sieve be provided with by bottom, classification chamber and interior feedback outlet (13) the jet lip limit of advancing to circulate is again gone into grinding chamber and is ground.
Regulate the rotating speed and the spacing of multipass sort sieve, controlled granularity of making the material powder.
The main frame total installation of generating capacity of present embodiment is 45～70kw, and complete machine weight is 3～3.5 tons, and the output granularity is the fine powder that 15～24 μ m cut off, and output is 0.6～1.5 ton/hour.Wherein 5～2 μ m account for and produce more than 70% of total amount.
