Description
Technical field
The utility model belongs to ball mill device technical field, is specifically related to a kind of ectonexine and forces axial flow and the ball-grinding machine circulated up and down.
Background technology
Adopt mechanical powerful ball grinding method when micro-nano powder is prepared in laboratory, power source driving device main axis makes the spherosome mechanical movement of agitation grinding, make to produce collision and relative fricting movement between abradant spherosome, make molecule be polished refinement.At present, mechanical ball grinding technique is becoming and is difficult to obtain by conventional method or one of the main technology of preparing of unavailable various metastable phase, non-equilibrium phase, super solid solution alloy, micro-nano powder etc.
Traditional ball mill stirs cross bar by means of only stirring the multilayer radial direction that main shaft is arranged, in circumference (namely tangential) the applying power of stirring ball-milling cup and motion, steel ball is acted on, be easy between spheroid due to mechanical ball milling produce and roll, relative coefficient of friction is little, causes and adopts traditional mechanical agitation main shaft to drive the rotation of layering multiple radial direction stirring cross bar to realize grinding the weak point that there are following two aspects:
(1) grinding effect between every layer is poor: because only make every layer of multiple radial direction grinding spheroid stirred near cross bar produce significant motion, the grinding spheroid in other region can not be made to produce significant relative motion, the spheroid between levels can not be made to produce significant relative motion, thus reducing the abrasive action of adjacent ball to the molecule be between two spheroids, grinding efficiency is low.
(2) lack of homogeneity of poor, the grinding refinement of ball milling bucket centre grinding effect: because stir main shaft when driving radial stirrer gear to rotate around the alignment of shafts, obviously, more larger away from the linear velocity stirring spindle centerline place, namely the closer to the circle ring area of ball milling bucket relatively large radius, the abrasive action of spheroid to material is larger.Otherwise in the minor radius cylinder near ball milling bucket center, the linear velocity stirring cross bar because radial is low, and the speed of related movement of the steel ball of this part is low.Cause the grinding effect of ball milling bucket near centre poorer than outer shroud place.The situation of the grinding refinement of the material in whole ball milling cup is made to have obvious difference.
(3) vibration noise is large: because traditional ball milling stirs the high-speed rotation of cross bar by radial direction, forces the steel ball being in this cross bar front to produce motion and realizes grinding material.The radial direction of especially most last layer stirs cross bar can be made steel ball severe impact ball milling wall of cup and stir main shaft, cross bar, thus causes huge vibration and noise.Especially will improve grinding efficiency, when strengthening the stirring speed of mainshaft, the vibration and noise of generation pollutes even more serious.
(4) heat in ball milling bucket not easily distributes: when mechanical powerful ball grinding method prepares micro-nano ground rice, because Ball-milling Time was up to tens hours, even up to a hundred hours, therefore, temperature in ball milling bucket can be very high, if cool not in time, can material deterioration be made, also can anneal because of grinding steel ball surface material time serious, and its hardness is reduced, wear no resistance.Therefore, requisite during the heat radiation of mechanical powerball grinding barrel.
The ball mill of traditional many cross bars of mechanical agitation type layering, due to the heat being positioned at ball milling bucket centre, will to distribute difficulty by outer field steel ball very large.And be in the steel ball in centre and material has no idea to force it to exchange with extraneous steel ball.Thus, the internal heat of traditional use for laboratory powerball grinding machine is not easily distributed.
