Description
Technical field
The utility model belongs to grinder field, especially relates to the centrifugal milling apparatus of a kind of convection rotary type land plaster.
Background technology
Land plaster grinder is a kind of machinery equipment that gypsum is pulverized, land plaster grinder of the prior art is that the bulk materials after fragmentation is sent into main frame grinding chamber, subsequently by perching knife scoop up enter between grinding roller and ring, rolled rub with the hands broken, powder after rolling is blown into and in analytical engine, carries out sorting under the wind-force effect of blower fan, the powder that the does not reach fineness grinding chamber that falls back again carries out regrind, this kind of type body volume is larger, there is very large rotary inertia, and can produce compared with big bang and noise during equipment operation, not only can cause machine running process steady not, also can shorten the service life of each parts, in addition, it is very low that the material of this kind of type once grinds to form power, cause land plaster repeatedly to be ground, product grading is extremely inhomogeneous, affected the quality of product.
Summary of the invention
It is steady that problem to be solved in the utility model is to provide a kind of running, the high and centrifugal milling apparatus of even-grained convection rotary type land plaster of grinding efficiency.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the centrifugal milling apparatus of a kind of convection rotary type land plaster, comprise grinding mechanism, drive unit, main shaft, countershaft, deflector chute, bulk cargo dish, receiving hopper and casing, is characterized in that: described grinding mechanism is arranged at center in casing; Described drive unit comprises the first driving mechanism and the second driving mechanism that is symmetricly set in grinding mechanism both sides; The upper end of described main shaft is connected with the first driving mechanism; The lower end of described countershaft is connected with the second driving mechanism; Described bulk cargo dish is installed on main shaft; Described deflector chute is installed on the inner machine wall of casing, between bulk cargo dish and grinding mechanism; Described receiving hopper is fixed on casing, around countershaft, is arranged at grinding mechanism below.
Described casing upper end is provided with charging aperture, and bottom is provided with discharging opening.
Described the first driving mechanism and the second driving mechanism are provided with motor, belt wheel and driving-belt, and described motor rotates by driving-belt driving pulley.
Described grinding mechanism comprises mill and at least two mixing rolls, and described mill is arranged on countershaft; One end of described mixing roll is connected with main shaft, and the other end is arranged in mill.
Described mill is provided with wear ring and powder leakage hole, and described wear ring is arranged on mill sidewall, is close to mixing roll lower end; Described powder leakage hole is through mill bottom.
Described main shaft and countershaft direction of rotation.
Owing to adopting technique scheme, during loose rotation of disc on main shaft, material can along the circumferential direction enter uniformly between mill and mixing roll under the effect of centrifugal force, therefore the more conventional mill vibration of mill running is little, operates steadily, and has extended the service life of machine; Meanwhile, by the mixing roll on main shaft and the mill subtend spin finishing material on countershaft, grinding efficiency is increased substantially; In addition, the material powder after pulverizing can be discharged by the powder leakage hole on mill in time, avoids repeatedly being ground, and has improved product grading uniformity.
The beneficial effects of the utility model are: have running steady, the high and epigranular of grinding efficiency, the advantage such as machine service life is long.
