Abstract
The invention discloses a compound pendulum type roller mill which is capable of increasing the grinding area and improving grinding efficiency, high in efficiency and low in consumption. The compound pendulum type roller mill comprises a swinging box, wherein a bottom plate of the swinging box is in an arc shape, and the swinging box is equally divided into two parts at bearing central shafts at the two ends so that the swinging box tends to be in a two-force balance state in the moving process. The swinging box is hinged to the two ends of a support through the bearing central shafts. Spring boosters are mounted on the ground and located on the two sides of the swing of the swinging box. The spring boosters and a driving device jointly drive the swinging box to conduct compound pendulum motion under resultant force. The driving device is a crank and rocker mechanism. A box body is divided into two or more working bins by partition plates. Each partition plate is provided with material fineness control and material passing holes. A grinding medium roll is placed in each bin and conducts curvilinear motion to grind and impact ore to be thin and broken.
Description
Technical field
The present invention 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, ore is ground the powdered that disappears by the frequent use mill equipment that disappears, existing mill disappears equipment mainly ball mill, and it is over half that mill disappears that the grinding energy ezpenditure of equipment should account for that total manufacturing machine consumes, but the effective power of ball mill is the highest is no more than 6%.Existing ball mill is for fuselage with a circular cylindrical shell, in cylindrical shell, load onto the milling medium (steel ball) that accounts for volume 25%-45% and by the ore ground, drive cylindrical shell to rotate through motor, drive steel ball to rise, then rely on steel ball gravitional force, leave shock and mill and to disappear ore.There is following shortcoming in existing ball mill:
1, milling medium (steel ball) high consumption:
In grinding process, because milling medium (steel ball) leaves, rushes down the working method point cantact mill fallen and to disappear ore, 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; Have space between milling medium (steel ball), 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, during running, milling medium and ore are positioned at cylindrical shell side arcuately section all the time, and by weighing, the milling medium (steel ball) of tens of tons and material side lift certain altitude, produce the displacement of the gravitional force discrepancy in elevation and leave acting.
Summary of the invention
The present invention is to solve the problems of the technologies described above, and provides one can increase grinding area, improve grinding efficiency, efficient compound pendulum type roller mill.
Technical solution of the present invention is: a kind of compound pendulum type roller mill, comprise frame, its special character is: in described frame, arrange swing case, load-bearing central shaft is respectively equipped with in the load-bearing center at the axial two ends swinging case, described swing case is hinged on support two ends by load-bearing central shaft, the base plate swinging case is arc, outside swing box plate, be positioned at swaying direction both sides be respectively equipped with buffer board, roller is placed in described swing case, swinging the drive unit and two groups of spring assist devices that on the ground below case, setting is connected with swing case, described drive unit is by motor, the reductor be connected with motor output shaft, be arranged on the eccentric wheel on speed reducer output shaft, the damp connecting lever be connected between eccentric wheel and swing case sidewall forms, two groups of spring assist devices lay respectively at below corresponding buffer board.
Further, be separately installed with bearing at the axial two ends of frame, described load-bearing central shaft is arranged in corresponding bearing respectively.
Further, described swing chamber interior wall is provided with multiple dividing plate vertically, swing case inside is divided into multiple barreling storehouse by described dividing plate, and is provided with material hole in the bottom of each dividing plate, is provided with discharge gate at the endplate root swinging case.
Further, grinding liner plate is set at the inner surface swinging box plate, strengthens and roll grinding effect.
Further, case lid is set in described swing box top, is provided with material inlet at the end face of case lid, prevent ore from dispersing to outside swing case.
The invention has the beneficial effects as follows:
1, the drive unit be connected with swing case is the crank and rocker mechanism be 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 swinging on the arc inner bottom plating in case, swing case and constantly create the left and right discrepancy in elevation to milling medium roller while doing compound motion, make roller do curvilinear motion and roll shock ore with reaching order in small, broken bits, and for line face contacts between roller with ore, add contact area, improve grinding efficiency.
2, the spring assist device swinging case swaying direction both sides is arranged on, make swing case in swing process, spring assist device compresses by the swing centripetal force of case and the gravity inertial potential energy (curve accelerated motion) of roller, make spring assist device storage elasticity potential energy, when fuselage backswing, the elastic potential energy that spring assist device stores is discharged into and swings on case, and the drive unit of assisting outer force motor etc. to form the with joint efforts common swing case that drives does work, and reduces the power output of motor.
3, load-bearing central shaft is respectively equipped with in the load-bearing center swinging the axial two ends of case, swing case is swung when static bilateral symmetry is arranged, motion time trend towards balance between two forces state (swing both sides consubstantialities, etc. large, oppositely, conllinear), (gravitional force, elastic potential energy, centripetal force) active force and the reaction force of having used object itself do work simultaneously (with producing with disappearing), eliminate side lifting force amount, improve the utilization rate of energy.
In sum, this compound pendulum type roller mill changes the mode of grinding ore, eliminates the strength of lifting side and has used the external force of spring assist device, saving power consumption more than 80%.Change milling medium duty, it by point cantact clash into form change into line face contact roll form, milling medium subtracts consumption more than 30%, substantially increases operating efficiency simultaneously.
