For realizing the object of the invention, provide following technical scheme: circle end socket Centrel driving ball mill, comprise bottom support, the balling drum be arranged on support, the rotating shaft at cylinder two ends, reductor and motor, it is characterized in that two ends rotate pedestal in two end axles bearing, one end is passed bearing block and is connected with speed reducer output shaft by shaft coupling, and motor is located at below reductor and is connected by belt pulley.
As preferably, balling drum two ends end socket is dome-type lid.Can avoid or reduce the brinelling of steel ball to two ends end socket, avoid dead angle buildup, and improve service efficiency.
From the data of applying unit feedback, old-fashioned ball mill two ends end socket more easily weares and teares worn out compared with stack shell, and position is apart from center 2/3 radius, and this position is the peak that steel ball is thrown, and is therefore stressedly easily worn through greatly.Two ends end socket changes three-dimensional hemispherical into then can avoid this situation, and oval capping can reduce the impact of steel ball to capping, plays a cushioning effect.Steel ball directly knocked upright capping in the past, and impact is very large; Present steel ball, after touching oval capping, due to its surperficial radian, therefore can move on along its radian direction and then fall, avoid or substantially reduce the brinelling of steel ball to ball mill two ends, add service life.Ball mill two ends in the past and stack shell are that 90 degree of right angles are connected, and after general use some months, junction just there will be buildup, cumulative, becomes a dead angle (as Fig. 4), needs the often person of sending someone to enter ball grinder interior and clean, waste time and energy; And the material that amasss more or less can be mixed in the material of new mill, it becomes the material of the new mill of branch's impact, and abrasive material effect is undesirable.Oval capping is connected with stack shell, and original an angle of 90 degrees is disappeared, and there is radian junction, can not buildup again, also not needing the person of sending someone to enter, cylindrical shell is interior cleans, and more can not affect result of use.Ball mill barrel inside becomes a seamless abrasive material space without dead angle, and the oval capping at two ends then can drive steel ball and material to continue to carry out abrasive material in oblong surface, and this point is not then accomplished in former right angle capping.Make ball mill service efficiency greatly strengthen like this, abrasive material better effects if, also save the part energy.
As preferably, the material rotating plate that in balling drum, welding 34 is different in size, wherein stack shell 18, distributes in alternating expression, 16, two ends, the distribution in " rice " font.As preferably, be the stirring thickness of slab 40-50mm of alternating expression distribution in stack shell, high 30-40mm, long 60-80mm.Not only be conducive to intersecting sliding tackle stirring to carry out fragmentation, and give ball and expect that carrying out abrasive material provides enough distances.The material rotating plate staggered also makes each stirring and sliding tackle have a time difference, and this time difference is also very short, is just conducive to the skyborne shock of ball material broken.Meanwhile, the ball material that staggered material rotating plate makes every root material rotating plate dig can not be too many, laborsaving province energy, plays a significantly greater role for saving energy." rice " font material rotating plate on the end socket of two ends not only makes the material rotating plate of stack shell and end socket join together, during stirring abrasive material more convenient and 360 degree without dead angle, simultaneously also certain protective effect is served to end socket, extends the service life of end socket.
As preferably, the connecting hole aperture on the sleeve of shaft coupling left and right is set to small one and large one, is arranged with nylon jacket in the connecting hole of large aperture, is through in nylon jacket is fixedly connected with small-bore connecting hole by pin.Traditional shaft coupling middle to be connected by iron and steel pin, very easily fractures and once fracture maintenance is pretty troublesome.Nylon column pin coupler solves this difficult problem, and iron and steel pin changes the hardness that nylon jacket iron pin not only ensure that pin into, also provides toughness simultaneously, no longer to iron pin direct friction when making shaft coupling rotate, but friction nylon rod.And nylon rod has certain lubricity, nylon pin is not easily worn, durable.Maintenance also no longer bothers, once there be nylon pin to rupture, owing to having lubrication and the obstruct of nylon jacket, the fragment of the iron pin in the middle of nylon jacket can not stick into the gap in the middle of shaft coupling, so dismounting is easily, only nylon pin need be pulled down, change one new.Shaft coupling is divided into two parts, and a part connects the output shaft of reduction box, the main shaft of a part of connector drum.Two parts are connected by middle nylon pin.Nylon pin center is iron pin, the hollow nylon rod of iron pin outer race.12 nylon pins joined by 1 cover shaft coupling, and the connecting hole size on shaft coupling is separated by, and by macropore aperture docking on one side during connection, then penetrated from macropore by nylon pin, aperture stretches out screw thread, uses nut screwing clamping.
As preferably, support is monolithic construction.Ball mill barrel and running part are connected, conveniently assemble and disassemble and debugging maintenance.Ball mill in the past needs client's joints cement pillar to support cylindrical shell, and the basis linking cement pillar under ball mill to build not only thick but also wide, avoid cylindrical shell to shake, to waste time and energy and cost is excessive.Once build bad, ball mill shake, the main shaft that the time has grown stack shell two ends also can rupture because torsion is excessive, even also there will be ball milling cylindrical shell drop or roll out come accident, grave danger is formed to production safety and personal security.Integrated support overcomes the shortcoming of above-mentioned old-fashioned ball mill, cylindrical shell and transmission system are placed in same iron frame, debugging only need complete in manufacturer, after dispatching from the factory, applying unit only need place it in level ground, and the good buffer rubber gasket provided by manufacturer of ball mill framework underlay can use.Simultaneously because the whole parts of ball mill are all fixed in iron frame, it is more convenient to load and unload, and directly lifts to target ground with crane or forklift, avoids the parts disappearance in transportation or damages.All-in-one-piece framework eliminates the step that manufacturer on-sites install debugging, facilitates and produces and use both sides.
As preferably, stack shell and end socket all roll with the manganese steel plate that 25mm is thick and form, and can directly use, the life-span can reach more than 5 years.Traditional ball mill uses liner plate, and 2-3 must change once, and the usual replacement cycle is 1 week/platform, have impact on the production of applying unit greatly.Without the need to change liner plate with take end socket ball mill then solve this difficult problem, 1 week only need be shifted to an earlier date and manufacturer signs a contract a customized stack shell when needs are changed, then directly old stack shell is split out and change new can using, very convenient and centre does not affect production.
Beneficial effect of the present invention: the present invention, by improvement to cylindrical shell, support, shaft coupling and the kind of drive, substantially increases transmission efficiency, extends service life, energy-conservation, efficient, noise is low.
