Abstract
The invention discloses a high-energy ball mill. At present, the ordinary high-energy ball mill includes a stirring ball mill, a satellite type ball mill, a vibration type ball mill and the like, however, in practical work, the problem of low output mechanical energy density still exists. The high-energy ball mill comprises a grinding body fixing plate (5), wherein a motor (1) is arranged on the grinding body fixing plate; the motor is connected with a vertical shaft (6) through a belt pulley block (2); the grinding body fixing plate is connected with a damping spring (4); the damping spring is connected with a bump leveler (3); the vertical shaft is connected with a central cross sleeve shaft (8); the central cross sleeve shaft (8) is connected with a bearing (9); the bearing is connected with a torsional body (10); the torsional body is connected with a group of grinding tanks (7); the torsional body is connected with a spring tension balance system (11). The high-energy ball mill is applied to ball milling mineral separation of ore.
Description
technical field:
the present invention relates to a kind of high energy ball mill.
background technology:
high energy ball mill is the visual plant of carrying out mechanical alloying research and preparation superfines.High efficiency ball mill can be in the short period of time to being carried higher mechanical energy by ball-milled powder, make the material that ground shorter be in the time, to realize mechanical alloying.Even form nanocrystalline or non-crystalline material, and reduce the oxidation of material.At present conventional high energy ball mill has agitating ball mill, planetary ball mill, oscillatory type ball mill etc. multiple, but in practical work, still the low density problem of output mechanical energy.
summary of the invention:
the object of this invention is to provide a kind of high energy ball mill.
above-mentioned object realizes by following technical scheme:
a kind of high energy ball mill, its composition comprises: mill body fixed head, on described mill body fixed head, motor is installed, described engine is connected by belt pulley set with vertical shaft, described mill body fixed head is connected with damping spring, described damping spring is connected with bump leveller, described vertical shaft and center intersect sleeve and are connected, described center intersection sleeve is connected with bearing, described bearing with rock body and be connected, the described body that rocks is connected with one group of grinding jar, and the described body that rocks is connected with spring tension balance sysmte.
a kind of ball grinding method of high energy ball mill, first the method comprises the steps:, engine drives vertical shaft and center to intersect sleeve by belt pulley set and rotates, and drive that three ball grinders are done up and down, the compound of all around rock vibration, vibration frequency is 1000 beats/min; Secondly, at mill body fixed head, be arranged with four damping springs, damping spring is at engine and rock under the vigorous exercise of body and the effect of abrading-ball, produces strong multi-direction vibration.
beneficial effect:
ball grinding method of the present invention mixes more evenly abrading-ball with grinding charge material, fragmentation is finer, effect is stronger, thereby to the rapid miniaturization of grinding charge material or alloying.In addition, the inertia force owing to rocking body and produce certain centrifugal force and advance to direction of rotation in the process of high-energy ball milling, so high energy ball mill is also provided with spring tension balance sysmte, is controlled at grinding machine in the range of movement of regulation.Bump leveller of the present invention prevents from or reduces vibration being delivered to ground.
accompanying drawing explanation:
accompanying drawing 1 is structural representation of the present invention.
accompanying drawing 2 is that ball grinder of the present invention is arranged schematic diagram.
accompanying drawing 3 is horizontal sectional views of ball grinder.
the specific embodiment:
embodiment 1:
a kind of high energy ball mill, its composition comprises: mill body fixed head 5, on described mill body fixed head, motor 1 is installed, described engine is connected by belt pulley set 2 with vertical shaft 6, described mill body fixed head is connected with damping spring 4, described damping spring is connected with bump leveller 3, described vertical shaft and center intersect sleeve 8 and are connected, described center intersection sleeve is connected with bearing 9, described bearing with rock body 10 and be connected, the described body that rocks is connected with one group of grinding jar 7, and the described body that rocks is connected with spring tension balance sysmte 11.
embodiment 2:
the ball grinding method of above-mentioned high energy ball mill, first the method comprises the steps:, engine drives vertical shaft and center to intersect sleeve by belt pulley set and rotates, and drive that three ball grinders are done up and down, the compound of all around rock vibration, vibration frequency is 1000 beats/min; Secondly, at mill body fixed head, be arranged with four damping springs, damping spring is at engine and rock under the vigorous exercise of body and the effect of abrading-ball, produces strong multi-direction vibration.
embodiment 3:
described high energy ball mill, the present invention adopt Cu/TiB2 composite, nitrogen-contained stainless steel, Ag/REO contact material, etc. special material.The present invention utilize abrasive media (spherical or bar-shaped) in doing the cylindrical shell of dither to material impact, the effect such as friction, shearing and make fine grinding and the Ultrafine Grinding equipment of crushing material.In work, oscillatory type, mill tube shape and pack completeness are depended in the motion of medium.Amplitude, the frequency of vibration are higher, raw meal particle size is thinner, material pack completeness is larger, granularity is thicker, and the pack completeness of medium is advisable with 60%-80%, within the specific limits, being directly proportional to grinding time than table subcutaneous ulcer is long-pending of material, according to feeding granularity, by selecting suitable media size, regulate the amplitude of vibration and the pack completeness of frequency and feeding coal and medium etc. to obtain desired fineness of materials by U.
embodiment 4:
described high energy ball mill, stirring-type high energy ball mill stirs abrasive media by agitator and produces impact, friction and shear action, makes crushing material.Abrasive media produces son by irregular movement to material and plants active force: grinding medium is interrogated and impacted mutually the impulsive force producing; Abrasive media rotates shearing force and the frictional force producing; Abrasive media is inserted the left space of stirring pipe and the impact that produces.At stirring-type high energy ball mill, in energy-saving ball mill, usually use spherical grinding medium, its average diameter is less than 6Mm, during for ultra-fine grinding, is generally less than 1mm.The peripheral speed of agitator is generally 4-20 little s, and speed is higher, and the wearing and tearing of agitator are more serious.
planetary high-energy ball mill: the feature of planetary ball mill is that the motion mode of abrading-ball is more complicated. the energy of acquisition is higher, and this kind of ball mill, under identical fourth skill parameter, can be prepared several groups of materials simultaneously, is convenient to carry out scientific research, most widely used general.Its operation principle is, at the circumference-k of rotating disc, several ball grinders of doing again high speed rotation with rotating disk revolution are housed.Abrading-ball in ball milling distance, under the effect of inertia force, forms very large high-frequency percussion and friction to material, carries out quick fine grinding.
