Description
Technical field
The utility model relates to the ore reduction milling equipment for metal and non-metal mine industry, particularly a kind of compound pendulum type roller mill.
Background technology
In metal and non-metal mine industry, often use the mill equipment that disappears that ore is ground to the powdered that disappears, the existing mill equipment that disappears is mainly ball mill, and the grinding energy consumption of grinding the equipment that disappears should account for over half that total manufacturing machine consumes, and is no more than 6% but the effective power of ball mill is the highest. Existing ball mill is taking a circular cylindrical shell as fuselage, in cylindrical shell, load onto and account for the milling medium (steel ball) of volume 25%-45% and the ore being ground, drive cylindrical shell rotation through motor, drive steel ball to rise, then rely on steel ball gravitional force, leave and clash into and the mill ore that disappears. There is following shortcoming in existing ball mill:
1, the high consumption of milling medium (steel ball):
In grinding process, because milling medium (steel ball) is to leave, rush down the working method point contact mill the falling ore that disappears, contact area is little, and the mill efficiency that disappears is low; Also there will be the invalid direct shock between steel ball and steel ball, cause the autophage of ore grinding valency matter; Between milling medium (steel ball), have space, when steel ball clashes into ore, mineral have the phenomenon of yielding, buffering, left and right slippage simultaneously, and there is dead angle in acting space.
2, motor driver power consumption is high:
Ball mill belongs to eccentric gearing state, power consumption is high, when running, milling medium and ore are positioned at all the time cylindrical shell one side and are arching section, and milling medium (steel ball) and the material side of tens of tons of weighing lifted to certain altitude, produce the displacement of the gravitional force discrepancy in elevation and leave acting.
Summary of the invention
The utility model is in order to solve the problems of the technologies described above, and provides one can increase grinding area, improves grinding efficiency, efficient compound pendulum type roller mill.
Technical solution of the present utility model is: a kind of compound pendulum type roller mill, comprise frame, its special character is: swing case is set in described frame, load-bearing center at the axial two ends that swing case is respectively equipped with load-bearing central shaft, described swing case is hinged on support two ends by load-bearing central shaft, the base plate that swings case is arc, be positioned at swaying direction both sides outward at swing box plate and be respectively equipped with buffer board, in described swing case, place roller, the drive unit and the two groups of spring assist devices that are connected with swing case are set on the ground below swing case, described drive unit is by motor, the reductor being connected with motor output shaft, be arranged on the eccentric wheel on speed reducer output shaft, be connected to eccentric wheel and swing the damp connecting lever composition between case sidewall, two groups of spring assist devices lay respectively at corresponding buffer board below.
Further, be separately installed with bearing at the axial two ends of frame, described load-bearing central shaft is arranged on respectively in corresponding bearing.
Further, on described swing chamber interior wall, be provided with vertically multiple dividing plates, swing case inside is divided into multiple barreling storehouse by described dividing plate, and be provided with material hole in the bottom of each dividing plate, is provided with discharge gate in the end plate bottom that swings case.
Further, at the inner surface that swings box plate, grinding liner plate is set, strengthens and roll grinding effect.
Further, in described swing box top, case lid is set, is provided with material inlet at the end face of case lid, prevent that ore from dispersing to swinging outside case.
The beneficial effects of the utility model are:
1, the drive unit being connected with swing case is the crank and rocker mechanism being jointly made up of motor, reductor, crank and connecting rod, electric machine rotation drives swing case to do compound motion, and be placed with roller on the arc inner bottom plating swinging in case, swing case and constantly create the left and right discrepancy in elevation to milling medium roller in doing compound motion, making roller do curvilinear motion rolls and clashes into ore and reach order in small, broken bits ground, and between roller and ore for line face contacts, increase contact area, improved grinding efficiency.
2, be arranged on the spring assist device that swings case swaying direction both sides, make to swing case in swing process, swinging the centripetal force of case and the gravity inertial potential energy of roller (curve accelerated motion) compresses spring assist device, make spring assist device storage elasticity potential energy, in the time of fuselage backswing, the elastic potential energy that spring assist device stores is discharged into and swings on case, and the drive unit of the compositions such as auxiliary outer force motor with joint efforts common driving swings case acting, has reduced the power output of motor.
3, be respectively equipped with load-bearing central shaft in the load-bearing center that swings the axial two ends of case, make to swing case when static, swing that bilateral symmetry is arranged, when motion trends towards balance between two forces state (swing both sides consubstantiality, etc. large, oppositely, conllinear), (gravitional force, elastic potential energy, centripetal force) active force and the reaction force of having used object itself simultaneously do work (with producing with disappearing), save side lifting force amount, improved the utilization rate of energy.
In sum, this compound pendulum type roller mill has changed the mode of grinding ore, has saved the strength of side act the external force of having used spring assist device, saves power consumption more than 80%. Changed the duty of milling medium, it changes the contact of line face into by a contact impact form and rolls form, and milling medium subtracts consumption more than 30%, has greatly improved operating efficiency simultaneously.
