Abstract
The utility model discloses an end plate of roller ball grinder, composed of a plurality of taper end plates and fixing bolts, wherein the working surface of the end plate is arranged with a cam in hyperboloid arc shape, one end of the taper end plate near the barrel is arranged with square platforms at two sides, a plurality of taper end plates are parallel arranged into ring shape which diameter is relative to the diameter of the roller of ball grinder, the taper end plate is arranged with an ellipse bolt through hole, the fixing bolts engaged with stop nuts are fixed on the end face of the roller, therefore, the utility model provides an end plate used in the roller of roller ball grinder. The utility model has better abrasion resistance, vibration resistance, long service life of bolts, improved ball carriage ability on end plate, prolonged service life of end plate, quick and periodical exchange, reasonable structure, simple installment, reliable operation, low cost, high economic benefits and wide application.
Description
Affiliated technical field:
The utility model relates to power industry powder process metallurgical machinery equipment technical field, particularly relates to a kind of ball tube mill end plate.
Technical background:
Ball mill is most widely used plant equipment in metallurgical machinery equipment, the kind of ball mill is a lot, wherein the operation principle of ball tube mill is on rotatable inner wall of rotary drum abrasion-proof backing block to be installed, at the cylinder two ends wear-resistant end plate is installed, form the tubular liner plate layer of sealing, in tubular liner plate layer, put into the technology steel ball, after the material of large volume enters tubular liner plate layer, rotation by cylinder makes the frictional force that produces between material and the steel ball, thereby make material by levigate, end plate is as directly withstanding shocks its material of critical piece of power and abrasive resistance and the service life that structure has just determined ball mill.Traditional liner plate is a sector structure at present, combine by the welding of polylith vertebra shape plate, the reinforcement of its vertebra shape plate is a Nogata shape, the dribbling ability that fracture reduces grinding machine staving end plate appears easily thereby be in operation, condition is abominable altogether because cylindrical shell moves simultaneously, steel ball in the cylindrical shell and material are periodically to cylindrical shell end plate impact shock, causing end plate to damage comes off, because end plate is different with the shell liner operating mode, service life difference, can't in time be changed after the damage, material and liquid slurry mixture in the cylindrical shell are leaked along the bolt hole place, be polluted working environment.How overcoming the shortcoming that the fan-shaped end plate of above-mentioned ball mill occurs, is the task that current urgent need solves in this area.
Summary of the invention:
The purpose of this utility model is to provide that a kind of wear resistence is good, the dribbling ability of anti-vibration, raising ball mill barrel end plate, prolongs the service life of ball mill end plate and the ball tube mill end plate that can periodically exchange fast.
In order to achieve the above object, the utility model adopts the technical scheme of following structure: a kind of ball tube mill end plate, form by polylith taper end plate and fastening bolt, be characterized in, the working surface of taper end plate is provided with the boss of hyperboloid circular shape, arc radius is that benchmark is symmetrically distributed or is on the center line of branch angle entad and distributes entad to divide angle line, one end of the nearly cylindrical shell of taper end plate is square platform, the outline line of podium level direction both sides is parallel to the both sides of entad dividing the angle line symmetrical distribution entad to divide angle line, polylith taper end plate parallel arranged becomes annular, the annular diameter is corresponding with the balling drum diameter, the taper end plate is provided with oval bolt hole, be fixed on fastening bolt on the end face of balling drum, constitute the ball tube mill end plate.
The boss of hyperboloid circular shape on the above-mentioned described taper end plate working surface, its arc radius is the 50-150 millimeter.
The nearly cylindrical shell of above-mentioned described taper end plate end both sides be square platform, the height of its platform is the 70-120 millimeter, berm width is identical with end plate thickness.
Above-mentioned described fastening bolt adopts the high-strength bolt that the retaining screw nut is arranged.
Structural principle of the present utility model is such, the taper end plate adopts the manufacturing of plastic metal anti-friction material, can adopt ni-hard cast iron series alloy or other extension coefficients low as adopting chrome molybdenum series anti-friction material, avoid because the ductility after the installation of taper end plate causes the failure by shear to bolt, and the hyperboloid circular shape boss that is provided with on the taper end plate, then avoided the taper end plate in the course of the work because slight crack and fracture that the impact of steel ball and material causes, increase simultaneously the locomitivity of inner wall of rotary drum dribbling and material again, improved exerting oneself of cylinder.Two oval bolt holes are set on the taper end plate, fastening bolt is installed in the bolt hole, cooperate the nut that has the retaining screw thread to be installed on the body end surface, the assurance nut can not made a concession in vibrations and be come off, each taper end plate all is applied with prestressing force in installation process, each parts is still accepted prestressed circulation and is added up at work, therefore can guarantee that each parts are in the integrated operation of prestressing force duty in the course of the work.
Owing to adopted the above-mentioned ball mill tip plate configurations that forms by parts such as taper end plate that has hyperboloid circular arc boss and retaining nut combination installation, make the utility model overall wear resistance good, anti-vibration, bolt is sturdy and durable, nut stands one's ground and does not come off, improve the dribbling ability of ball mill barrel end plate, prolong the service life of ball mill end plate and can periodically exchange fast, make the problem of not keeping in repair end plate behind the ball mill installation and operation, realized rational in infrastructure, install simple, reliable operation, manufacturing and operating cost are low, the economic benefit height is convenient to vigorously promote the use.
