BALL OR TUBE MILL Filed Des. 7, 1933 nun...
Patented Dec. 215,` 1934 i BALL on TUBE MILL r l Joseph Sheehan, Charbon, Australia Application December?, 1933, Serial No. 101,381 1 i In Australia September 19, 1932 i e e 5` claims.
This invention relates to ball or tube mills which are utilized for crushing or pulverizing materials.
Referring to the accompanying drawing in which the invention is illustrated- Figure 1 is a longitudinal central sectional elevation of one construction of the ball or tube mill;
Figure 2 is a cross-sectional elevation on line 2--2 of Figure l;
Figure 3 is a detail perspective view of one arrangement of vanes which are utilized in the interior of the ball or tube mill;
Figure 4 is a View showing a modified arrangement of the vanes;
Figure 5 is a similar view to that of Figure 4 showing a modified form of vanes;
Figure 6 is a perspective view of a series of vanes as shown in Figure 5; and
Figures 7 and 8 are sections on planes '1 -'7i and 8-8 respectively'of Figure 6.
According to the invention a cylindrical barrel or drum 1 is provided which may be subdivided into a plurality of compartments 2 by transverse perforated partitions 3. Such barrel 1 is rotatably mounted and it is furnished with a feed opening 5 and a discharge opening 6. Each compartment 2 carries a number of metallic vballs 8, wherewith material f ed to the barrel 1 can be crushed or pulverized therein. On the inner periphery of each compartment 2 are rigidly mounted a number ofspaced vanes 9 of suitable `construction and arrangement.
In one such form of construction and arrangement each compartment 2 of the barrel 1 is provided vvith two series of peripherally spaced vanes 9 set angularly to each other. Such vanes 9 may consist of angular plates (Figure 3) which eX- tend from the end walls l0 or partitions 3 of a compartment 2 ofthe barrel 1 to the centre thereof, such plates 9 are disposed in oppositely inclined or oblique positions. Instead of utilizing the angular plates 9 longitudinal blocks l2 may be employed (Figures 5 to 8); such blocks 12 may be fixed to the inner periphery of the `compartments 2 of the barrel 1 .in any appropriate manner such as by bolts 15, and they may be set therein parallel to the longitudinal axis 0f the barrel l. Each of theblocks 1,2 is provided with a chamfered leading f ace 13, and said face 13 is also bevelled from one end to the other as at 14, such bevelled face inclining toward the centre of the compartments 2.
According to another form of said construction and arrangement, instead of the vanes 9 on the inner periphery ofthe barrel`1 extending in one piecefrom-'the end walls 10 of 4a compartment 2 to the centre of such compartment, such vanes 9 are divided into sections (Figure 4) in jagged formation.
In operation, on the barrel 1 being rotated and charged with material to be treated, the vanes 9 or blocks 12 will lift the balls 8 to fullest height. Such balls 8 on falling off the vanes 9 or blocks 12 will be brought into contact with material in the barrel l toward the centre of the compartments 2 of the `barrel 1 and such material will thus be crushed or pulverized; the balls 8 will also be prevented from accumulating against the perforated partitions 3 of the barrel l, and pulverized material will thus not be retarded in its passage through the perforations on the partitions 3 of the barrel 1.
I claim:
1. A ball or tube mill comprising a rotatable chamber to which material to be pulverized is feedable and from which pulverized material is deliverable the said chamber also carrying a plurality of metallic balls, and a series of angular vanes on the peripheral interior of said chamber which are disposed in spaced rows and in oppositely inclined positions and set to provide a space between their contiguous ends whereby they will be adapted to positively and independently lift said balls and to permit their rolling and falling therefrom through the space provided between their 'contiguous ends on to material in the said i chamber for the pulverization of said material.
2. A ball or tube mill comprising a rotatable chamber to which material to be pulverized is feedable and from which pulverized material is deliverable the said chamber also carrying a plurality of metallic balls, and a series of angular vanes consisting'of blocks which are set in spaced rows and end to end on the peripheral interior of said chamber said vanes extending from the respective end walls of the chamber and being disposed in oppositely inclined positions and set to provide a space between their contiguous ends whereby they will be adapted to positively lift said balls and to permit their rolling and falling therefrom through the space provided between and disposed in jagged formation on the peripheral interior of said chamber which are disposed in oppositely inclined positions and in spaced rows and set to provide a space between their contiguous ends whereby they will be adapted to positively lift said balls and to permit their rolling and falling therefrom through the space provided between their contiguous ends on to material in the said ,cham-ber for. thepulverization of said material. y
4. A ball or tube mill comprising a, rotatable chamber to which material to be pulverized is feedable and from which pulverized material is deliverable the said chamber also carrying a plurality of metallic balls, and a -series of angular varies consisting of angular plates on the peripheral interior of said chamber and 'carried in sepa-1 rate compartments thereof said vanesha'ving rel-v atively Wide carrying surfaces and being disposed in oppositelyinclined positions and in spaced `rows .and having their adjacent ends spaced from eachother whereby they will be adapted to positively and independently lift said balls and to permit their rolling and falling therefrom through the space provided between their adjacent ends on to material in the said chamber for the pulverization of said material.
5. A ball or tube mill comprising a rotatable chamber to which material to be pulverized is feedable and from which pulverized material is deliverable the said chamber also carrying a plurality of metallic balls, and a series of langular vanes consisting of blocks which are set in spaced rows and end to end on the peripheral interior o'f said chamber which are disposed in oppositely inclinedy positions and set to provide a space between their contiguous ends whereby they will be adapted to lift said balls and to permit their rolling and falling therefrom through the space provide'dbetween their contiguous ends towards the centre of the rotatable chamber and on to material therein for the y material.
