Description

Hard material grinding Special ball mill
Technical field
The utility model relates to ball mill, is specifically related to hard material grinding Special ball mill.
Background technology
Ball mill is after material is broken, then carries out the key equipment pulverized.It is widely used in cement, silicate product, New Building Materials, refractory material, chemical fertilizer, nonmetallic ore and the production industry such as non-ferrous metal ore and glass ceramics, carries out dry type or wet type grinding to various ore and other grindability material.During ball mill work, its cylindrical shell rotates, and drives the material in cylinder and mill ball to carry out rotations to form drop percussion movement, relies on mill ball, mutual shock between material and liner plate and mutual rubbing action that lump material is made powder.
Existing ball mill is generally in cylinder, load multiple identical steel ball, specification is consistent, for hard materials such as quartz, zircon sand and aluminium oxide, in the process of grinding material, adopt the mill ball of single size can affect grinding efficiency and fineness of grind, and adopt steel ball, the tenor in material can be caused to increase, affect purity and the whiteness of product, mill ball serious wear, need often to add or change, increase cost.The size of some material is applicable to the specification of mill ball not all, after being ground to certain broken degree, has been not suitable for again by ground for those materials in small, broken bits compared with the mill ball of large gauge before, the efficiency of grinding can decline, specific energy consumption uprises, and cause cost high, quality is uneven.
Utility model content
Technical problem to be solved in the utility model is existing ball mill for there is inefficiency, energy consumption is large, fineness of grind is uneven problem in the process of lapping of hard material.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is to provide a kind of hard material grinding Special ball mill, comprise cylindrical shell, drive unit, the two ends of described cylindrical shell are respectively equipped with feed arrangement and drawing mechanism, on the lateral surface of described cylindrical shell, cover has belt, described drive unit rotates by driving described belt and then drives described barrel body rotation, the inner surface of described cylindrical shell is provided with the liner plate removably connected with described cylindrical shell, and described cylindrical shell is built with the mill ball of several different sizes.
In such scheme, described mill ball comprises the first mill ball, the second mill ball and the 3rd mill ball, and the diameter of described first mill ball, the second mill ball and described 3rd mill ball increases successively.
In such scheme, the diameter of described first mill ball is 10mm, and the diameter of described second mill ball is 20mm, and the diameter of described 3rd mill ball is 30mm.
In such scheme, on the outer surface of described second mill ball, multiple face pyramid grinding body is protruded at interval.
In such scheme, between described drive unit and described belt, be provided with transmission mechanism.
In such scheme, in such scheme, described feed arrangement and described drawing mechanism are respectively and adopt bearing assembly to realize removably connecting between described cylindrical shell.
In such scheme, described mill ball and described liner plate all adopt aluminium oxide material.
In such scheme, described drive unit adopts CD-ROM drive motor.
The utility model, by loading the mill ball of different size in cylindrical shell, to the hard material grinding targetedly and optionally of different size and shape, substantially increase grinding efficiency and fineness of grind, shorten milling time, reduce energy consumption to a certain extent, there is very high practical value.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is top view of the present utility model;
Fig. 3 is the enlarged drawing at A place in Fig. 1.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in detail.
As shown in Figure 1 and Figure 2, the utility model provides a kind of hard material grinding Special ball mill, comprise cylindrical shell 10 and drive unit 40, drive unit 40 adopts CD-ROM drive motor, the two ends of cylindrical shell 10 are respectively equipped with feed arrangement 12 and drawing mechanism 13, and feed arrangement 12 and drawing mechanism 13 are connected with adopting bearing assembly 11 between cylindrical shell 10 respectively, and stable connection is reliable, and detachable, be beneficial to maintenance and change.The hard materials such as quartz to be ground, zircon sand and aluminium oxide are sent in cylindrical shell 10 from feed arrangement 12, and in cylindrical shell 10, carry out grinding attenuates, and ground finished product materials is sent from drawing mechanism 13, enters down one program, and whole-course automation operates, and save manpower.
The cylindrical shell 10 of comparing in tradition, the length of the utility model middle cylinder body 10 and the ratio (i.e. draw ratio) of diameter diminish, the contraction in length of cylindrical shell 10, and preferred draw ratio, for being 2.5, effectively prevent the long grinding excessively caused of cylindrical shell 10 length.On the face, outside of cylindrical shell 10, cover has belt 20, drive unit 40 rotates by driving belt 20 and then drives cylindrical shell 10 to rotate, transmission mechanism 30 is provided with between drive unit 40 and belt 20, in the utility model, drive unit 40 adopts CD-ROM drive motor, and one end and the CD-ROM drive motor of transmission mechanism 30 are fixed, transmission mechanism 30 is driven to rotate by CD-ROM drive motor, the other end of transmission mechanism 30 connects belt 20, and cylindrical shell 10 rotates with belt 20, makes the material in cylindrical shell 10 polished in upset.
The inner surface of cylindrical shell 10 is provided with the liner plate 14 removably connected with cylindrical shell 10, liner plate 14 adopts aluminium oxide material, cylindrical shell 10 is built with the mill ball of several different sizes, because the material hardness all higher (generally in Mohs' hardness more than 6) of grinding, mill ball also adopts aluminium oxide material, aluminium oxide material has very strong abrasion resistance, effectively prevents metallic pollution.In the rotation process of cylindrical shell 10, material and mill ball rise under the frictional force of rotatory force and liner plate 14 drives, and after rising to certain altitude, mill ball falls, and clashes into material, relies on roll extrusion, friction, pulverizes material.
In the utility model, mill ball comprises the first different mill ball 15, second mill ball 16 of specification and the 3rd mill ball 17, the diameter of the first mill ball 15, second mill ball 16 and the 3rd mill ball 17 increases successively, in the process of lapping of many materials, selective and the specific aim of the grinding of mill ball to material of different size, substantially increases the uniformity of grinding efficiency and grinding.
See Fig. 3, preferably, the diameter of the first mill ball 15 is 10mm, and the diameter of the second mill ball 16 is 20mm, and the diameter of the 3rd mill ball 17 is 30mm.For larger-size material, 3rd mill ball 17 has good impact, can be smashed faster, for the material that size is less, second mill ball 16 and the first mill ball 15, in a dropping process, provide different shock dynamics, have selective molecular attraction and good sieving actoion to material, product granularity is even, decreases crushing phenomenon.
Be more preferably, on the outer surface of the second mill ball 16, multiple face pyramid grinding body 18 is protruded at interval, and for the material that hardness is larger, face pyramid grinding body 18 can produce more direct impulsive force to it as nail, accelerates the efficiency of pulverizing.
The utility model, by loading the mill ball of different size in cylindrical shell, to the hard material grinding targetedly and optionally of different size and shape, substantially increase grinding efficiency and fineness of grind, shorten milling time, reduce energy consumption to a certain extent, there is very high practical value.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structure change made under enlightenment of the present utility model, and every have identical or close technical scheme with the utility model, all falls within protection domain of the present utility model.
