Description
Technical field
The utility model relates to a kind of improved horizontal ball mill, can carry out grinding operation to material, belongs to the lapping device field.
Background technology
Horizontal ball mill is a kind of important dusty material process equipment, can pulverize processing to micro-nano magnitude powder, is widely used in the industries such as pottery, chemical industry, metallurgy and building.It generally is comprised of parts such as cylinder, power transmission shaft, bracing frame and rotary electric machines.During work, with abrading-ball and the material cylinder of packing into, rotary electric machine drives the uniform rotation of ball milling cylinder by power transmission shaft, and then drives abrading-ball and material rolls in cylinder.Like this, between material and abrading-ball and the ball milling cylinder wall friction and collision can occur, thereby make material levigate.In traditional horizontal ball mill, the cylinder horizontal positioned, such technology has the following disadvantages: crushing material efficient is low, and abrading-ball and material are easy to produce whole the slip in smooth cylinder, reduce the downthrust effect between them, thereby caused the crushing material inefficiency; Power consumption is high, because crushing material efficient is lower, needs to prolong Ball-milling Time, and energy consumption is increased accordingly; Material easily forms adhesion layer at inner wall of rotary drum, because the roll extrusion effect of abrading-ball makes material adhere at the ball milling inner wall of rotary drum and can't participate in process of lapping; Material is easy to pile up, because ball milling cylinder rotating manner is single, is easy to pile up formation at ball milling cylinder internal edges angular zone material and grinds the dead angle; The material particular diameter skewness, grinding effect is relatively poor, because single axial rotation only occurs in cylinder, each several part is inconsistent with respect to the angular speed of centre of the drum in the material cross section, even may form motionless layer to the central area near drum shaft, thereby cause so the inconsistent grinding material particle diameter skewness, grinding effect of causing of the grinding effect of material in the zones of different of cross section relatively poor.
For overcoming the deficiency of above-mentioned horizontal ball mill, there is the researcher to improve grinding efficiency by changing the ball mill motion mode, improve the ball milling effect, shorten Ball-milling Time.For example, the patent No. a kind of reducing cylinder ball mill that has been 200720049995.6 patent disclosure.This ball mill has mainly carried out improving design to cylinder, be the variable diameter tumbling that is formed by end cover, transition cone cylinder and central cylinder with before isometrical cylinder design, especially, the end cover diameter at two ends is less, is transitioned into gradually the larger central cylinder of diameter by the transition cylinder.Like this, there is speed difference in the linear velocity of material rotation in the linear velocity of material rotation in transition cone cylinder and the cylinder, the material linear velocity that has formed in a kind of cylinder two ends is low, the high grinding state of material linear velocity in the middle of the cylinder, material in the middle of the cylinder is to the two ends extrusion packing, and the two ends material so constantly circulates again to middle backward extrusion, grinding efficiency is improved greatly, thereby reach the purpose that reduces energy consumption.The patent No. a kind of vibrator that has been 00258809.9 patent disclosure.These ball mill characteristics be with frame through spring fitting on base, and a vibrating motor is installed also on the frame.Therefore, the ball milling cylinder is also vibrated when rotating, and makes abrading-ball and the collision between the material in the bucket, grinds not only evenly but also strong.Rotational guarantees that material forms rolling in cylinder, has avoided the grinding dead angle; Vibrational energy then make material on three-dimensional all to grinding and provide more powerful abrasive power.The patent No. is a kind of oblique cylinder ball mill of the patent disclosure of 201120330836.X, by with drum-inclined be fixed on the material rotational line speed that makes on the cylinder holder in the cylinder and have speed difference.
Although above-mentioned ball mill improves the grinding efficiency of ball mill by the extensional vibration that improves cylinder shape and increase cylinder, but these ball mill complex structures, bulky, noise is larger, and inventory is large, is not suitable for colleges and universities, the few multiple batches of experiment of material of R﹠D institution.In addition, above-mentioned ball mill ball milling cylinder is fixed, sealing is relatively poor, can't realize the as required conversion of replacing and dry method, wet ball grinding mode of cylinder flexibly.
The utility model content
For overcoming the deficiency of existing horizontal ball mill, the utility model is by improving roller frame, provides a kind of rational in infrastructure, low energy consumption, production efficiency high, is specially adapted to test and the ball mill of scientific research.
The utility model provides a kind of improved horizontal ball mill, comprising: be used for ball grinder, the horizontal positioned of loaded material and abrading-ball cylinder, described ball grinder and horizontal direction are fixedly supported on the support unit of cylinder with being predetermined angular and make described cylinder center on the rotary unit that horizontal axis rotates.
The improved horizontal ball mill that the utility model provides still adopts the cylinder of horizontal positioned, simple in structure, ball grinder and cylinder are independent respectively, by ball grinder being tilted easily to make material rotational line speed have speed difference but can not increase the complexity that arranges of cylinder, so simply mode changes the rotating manner of the horizontal grinding machine of traditional ball, realize that material and abrading-ball existing transverse movement around axis in ball grinder have again the lengthwise movement along axis, thereby make the material mixing of when pulverizing, also overturning, so that the abrading-ball motion mode is more diversified, avoid material the adhesion of ball milling tank skin and overstocking in the groove of ball grinder two ends, improved the grinding efficiency of material, reduced Ball-milling Time, improved the uniformity that material grinds.In addition, ball grinder independently arranges, thus have grinding jar and abrading-ball change convenient, mechanical milling process to material pollute little, as can to realize dry and wet way conversion, grinding efficiency is high, abrasive material is pulverized evenly, cylinder wall sizing and without grinding the advantage such as dead angle not.
Preferably, described support unit comprises that the below that can be inserted in described ball grinder or side to be fixedly supported on described ball grinder and horizontal direction a plurality of accessory plates in the described cylinder with being predetermined angular.
Can realize being obliquely installed of ball grinder by bottom and side insertion accessory plate at ball grinder simply like this, and as required, the large I at inclination angle is regulated according to the quantity of the accessory plate that inserts easily.
More preferably, described support unit also comprises the recess supports frame that holds described ball grinder and be arranged in described cylinder; Described a plurality of accessory plate comprises that the below that is inserted in described ball grinder and/or side to be fixedly supported on described ball grinder and horizontal direction a plurality of the first accessory plates in the described recess supports frame with being predetermined angular; And be inserted in the top of described recess supports frame and/or side described recess supports frame is fixed on a plurality of the second accessory plates in the described cylinder.
