Description
Technical field
The present invention relates to a kind of grinding attachment, particularly relate to a kind of ball mill.
Background technology
Ball mill is the key equipment that material is pulverized, and is widely used in production industries such as cement, pottery, construction material, refractory material, chemical fertilizer, black and non-ferrous metal ore and glass.Ball mill mainly is made up of ball grinding cylinder and transmission system, and transmission system drives ball grinding cylinder with suitable rotating speed rotation, and the impact and the abrasive action that make the interior material of cylindrical shell receive abrasive body (being generally steel ball, steel section, Ceramic Balls etc.) form thinner particle.
Abrasive body in the ball grinding cylinder of ball mill, ball grinding cylinder, material to be ground all is the bigger article of weight ratio, and ball mill constantly rotation down in working order, so the weight that ball mill need be loaded under the whole duty is very big.But, in producing at present the load carrier of ball mill commonly used be merely bearing and with the support of bearing fixing, so ball grinding cylinder integral body is bigger to the pressure of bearing; Make and produce bigger frictional force between the axle, bearing at when ball mill rotates ball mill two ends; Not only consumed energy greatly, and be easy to generate a large amount of heats, the wearing and tearing of bearing are big; Cause the operation expense of bearing to raise, and then cause reduce the service life of bearing.
Summary of the invention
The turning cylinder that the present invention is directed to ball mill barrel two ends in the present ball mill operation process is big to the pressure of bearing; Frictional force between axle and the bearing is big, power consumption is high; And then cause the problem such as weak point in service life, maintenance cost height of bearing, and a kind of ball mill is provided, comprise support, turning cylinder, ball grinding cylinder, bearing, reductor and motor; Said ball grinding cylinder is fixed on the support through turning cylinder and ball mill bearing rotationally; Also include the magnetic force assembly, said magnetic force assembly mainly comprises the magnetic force group, and said magnetic force group is corresponding each other with ball grinding cylinder.The magnetic force group is any one in permeability magnetic material and permanent-magnet material, permeability magnetic material and dc coil, permeability magnetic material and permanent-magnet material and dc coil integrated.The inventive point of the utility model is setting up of magnetic force group in the magnetic force assembly, promptly on the basis of general traditional ball mill, has set up this part of magnetic force group; Thereby through the cylindrical shell generation attraction of magnetic force to ball mill; Make ball grinding cylinder be in suspended state basically, eliminate or alleviate the pressure of ball mill, thereby eliminate or alleviate the frictional force between axle and the bearing bearing; Elimination or minimizing are because of fricative heat; Reduce energy consumption significantly, prolonged the life-span of bearing simultaneously, reduced the difficulty and the cost of bearing operation maintenance.
As the improvement of the utility model, said magnetic force assembly also comprises stressed ring, and said stressed ring is fixed on the ball grinding cylinder outer wall.Stressed ring is respectively any one in permeability magnetic material, permeability magnetic material and permanent-magnet material, permeability magnetic material and dc coil, permeability magnetic material and permanent-magnet material and dc coil integrated.Utilize the magnetic force group that stressed ring is produced attraction or repulsive force, thereby ball grinding cylinder is produced lifting force or thrust upwards.When stressed ring is permeability magnetic material and dc coil, permeability magnetic material and permanent-magnet material and dc coil integrated,,, can produce stronger active force so close with the magnetic force assembly because stressed ring itself has certain magnetic.Through position and the distance between stressed ring, the ball grinding cylinder on adjustment magnetic force group and the ball grinding cylinder; Perhaps adjust the kind of permanent magnets in magnetic force group and the stressed ring and quantity, the number of turn, the galvanic big or small direction of quantity or dc coil; Thereby the size and Orientation of adjustment magnetic force; Make the gravity equal and opposite in direction of magnetic force basic and ball grinding cylinder, material and ball-milling medium and in the opposite direction, thereby the weight of ball grinding cylinder, material and ball-milling medium is distributed on the fixed support in the magnetic force assembly.During assembly, there is suitable gap between magnetic force group and the stressed ring in the magnetic force assembly, thereby do not influence the normal operation of ball mill.Simultaneously, because the permeability magnetic material in the stressed ring plays magnetic screening action simultaneously, thereby eliminated the influence that magnetic field possibly exist the ball-milling medium in the ball grinding cylinder and material.
As the improvement of the utility model, said magnetic force assembly also includes fixed support, and said magnetic force group is fixed on the fixed support.When the magnetic force group produces active force to ball grinding cylinder or the stressed ring that is fixed in the ball grinding cylinder outer wall, the gravity of ball grinding cylinder, material and ball-milling medium is distributed on the fixed support, eliminate or alleviate the pressure of the axle at ball grinding cylinder two ends bearing.
As the improvement of the utility model, said magnetic force assembly is provided with two groups at least, and is arranged at the upper and lower of ball grinding cylinder respectively.
Many group magnetic force groups are the material bases that the magnetic force group are arranged on different positions, and the diverse location at ball grinding cylinder is provided with the magnetic force group as required, improves the load-carrying efficiency of magnetic force for ball grinding cylinder.When the magnetic force group is arranged on the top of ball grinding cylinder; The magnetic force group provides the magnetic that makes progress to lift power to ball grinding cylinder; When the magnetic force group is arranged on the bottom of ball grinding cylinder; The magnetic force group provides the magnetic that makes progress thrust to ball grinding cylinder, thereby eliminates or partly eliminate the pressure of the axle at ball grinding cylinder two ends to bearing.
As the improvement further of the utility model, also be provided with between said stressed ring and the ball grinding cylinder at a distance from magnetosphere.Adopt non-magnetic conduction substance at a distance from magnetosphere, thereby with adopting non-magnetic conduction substance to separate between stressed ring and the ball grinding cylinder, with the influence of further elimination magnetic field to ball-milling medium in the ball grinding cylinder and material.
In the present invention, the generation of magnetic force basis is permanent-magnet material or direct current coil.
In sum; After adopting the disclosed technical scheme of the present invention, ball grinding cylinder is under the suspended state, eliminates effectively or alleviate the pressure of ball mill bearing through magnetic field; Thereby alleviate or eliminated the frictional force between axle and the bearing; Not only practice thrift energy consumption, and prolonged the service life of bearing, reduced the maintenance difficulties and the cost of bearing.
