Abstract
The utility model relates to a small high efficiency ball mill for fining ore, having a horizontal roller. The lining board of the inner wall of the roller is divided into a front and a back two sections along an axial direction, wherein, the front section closing to the feed inlet of the roller is a flat and convex lining board, and the integral back section closing to the feed inlet of the roller is a flat lining board. After the ore enters the roller, the front section is lifted by the unsmooth lining board to move in a throwing and dropping mode so as to carry out coarse milling for the ore, and after the ore enters the back section, because the integral back section is the flat lining board, materials and a steel ball are moved in a sudden dropping mode so that the utility model enhances the milling and stripping action for the materials. The coarse and fine combining mode can raise the processing capability of the mill.
Description
The utility model relates to a kind of equipment of refinement solid material, particularly a kind of small-sized efficient ball mill of refinement ore.
At present, the small grinder that adopts of ore dressing plant all adopts grate ball mill basically.This ball mill is equipped with flat, protruding two kinds of liner plates on inner wall of rotary drum, flat, protruding liner plate distributes alternately, and protruding liner plate extends to discharge end from feed end always.The applicant finds that in production practices the disposal ability of this ball mill is lower, particularly change new liner plate after, disposal ability obviously reduces, and has only through treating wear liner more after a while, disposal ability just increases.The applicant thinks: this single material and steel ball flat, grate ball mill Yin Qinei that protruding liner plate distributes alternately always constantly fall from eminence, so ore is had stronger impact grinding effect, be easy to ore reduction is become thicker particle, and the mill stripping effect between material and steel ball is less, it is unfavorable that material further is finely ground to required fineness, and this also is the lower one of the main reasons of this type of ball mill disposal ability.
The purpose of this utility model is improved the weak point of above-mentioned existing ball mill, and a kind of small-sized efficient ball mill that can bigger raising disposal ability is provided.
The solution that realizes the utility model purpose is: the small-sized efficient ball mill that is provided has a horizontal drum, inner wall of rotary drum is provided with flat, protruding alternate liner plate.Improvements of the present utility model be liner plate on the inner wall of rotary drum along drum shaft to being divided into former and later two sections, wherein the front section near the cylinder charging aperture is flat, protruding alternate liner plate, all is flat liner plate near the back section of cylinder charging aperture.After ore enters cylinder, taken up by flat, protruding alternate liner plate in front section, steel ball and ore move in the mode of leaving, and ore is roughly ground.After entering the back section,,, strengthened the mill stripping effect of steel ball greatly, material has been finely ground to required granularity material so ore and steel ball after the corase grind move to rush down mode owing to be flat liner plate all.The disposal ability that has improved ball mill greatly that combines of this corase grind and fine grinding.
The front section of above-mentioned balling drum can be controlled in 1: 1～4 with the ratio of the axial length of back section, and concrete ratio can be determined according to the kind of institute's ore grinding stone, the feed preparation unit size before the mill etc.Generally speaking, feed preparation unit size is big, when ore is hard, and the shared ratio of the length of front section is bigger.
The utility model has the advantages that: a back section liner plate that only needs to have the grinding machine cylinder now all makes flat liner plate into, and other structure that need not to change grinding machine, can increase substantially the production efficiency of grinding machine.In addition, the manufacturing expense of flat liner plate is also low than protruding liner plate.The ball mill that uses the utility model to provide can change two sections ball millings that have the ore dressing plant now into one section ball milling, can reduce investment cost of equipment greatly like this.
Below in conjunction with accompanying drawing content of the present utility model is illustrated.
Fig. 1 is the drum segment structure diagram of an embodiment of the utility model.
Fig. 2 is the cutaway view at Figure 1A-A place.
Fig. 3 is the cutaway view at Figure 1B-B place.
Fig. 4 is the cutaway view at Fig. 1 C-C place.
As shown in Figure 1: the specification of balling drum 1 is 1500 * 1500 millimeters, 48 block lengths are housed are 720 millimeters strip liner plate on its inwall, and these liner plates are fixed on the inner wall of rotary drum by press strip 2.To being divided into two different sections, wherein close charging aperture 3 is front section 4 to liner plate in the cylinder along drum shaft, and near discharging opening 5 is back section 6.The liner plate of front section 4 has flat liner plate 7a and protruding liner plate 8, and they circumferentially are being alternately, as shown in Figure 2.The liner plate of back section 6 all is flat liner plate 7b, as shown in Figure 3.The length ratio of forward and backward section is 1: 3, and institute's ore grinding stone is quartz mine.In addition, at the intersection of front section and back section one changeover portion 9 is arranged, it is formed that this changeover portion 9 is that the height by protruding liner plate 8 reduces vertically gradually, and as shown in Figure 4, can make like this between thick, the fine grinding has a transition region.Ore enters cylinder by charging aperture 3, in the front section 4 (being unsmooth section) flat, that protruding liner plate is alternate, can with steel ball and material is higher throws, and ore is had the stronger percussion that leaves, and makes mineral be broken into the coarse grain shape; After entering back section 6 (level and smooth section), be mainly between material and steel ball and rush down grinding,, be enough to the coarse fraction material is milled to required fineness because this section is longer.The disposal ability of ball mill of the present utility model before improvement is 69 ton per days, improves reprocessing rate and reaches 102 ton per days.
