UNITED STATES ALFRED H. APTED, 0F GRAND RAPIDS, MICHIGAN.
BALL TUBE MILL.
Application filed April 3.
To all whom t may concern:
Be it known that l, ALFRED H. Arran, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have? invented new and useful improvements in Ball 4Tube Mills, of which the following is a specification.
The present invention relates to ball tube mills, or grinding and pulverizing machines; and its object is, generally, to provide a mill or machine of that character improved in various respects hereinafter appearing; and, more particularly, to provide such a mill comprising a hollow rotatable cylinder disposed axially horizontally and having in its middle portion spaced apart partitions perforated for the vpassage of the product therethrough into the space between them whence the product is discharged from orifices vthrough thecylinders side wall and, further, to provide a fixed member having a chamber surrounding the cylinderreceiving the product from said orifices; and further, to provide reinforcing means for the cylinder; and further, to provide the openings through said partitions so formed as to remain open and. free from clogging; and further, to provide such a mill as will economize weight and floor space and will minimize necessary parts.
rlhese objects are attained by, andthe invention finds preferable embodiment in, the structure hereinafter particularly described in the body of this specication and illustrated by the accompanying drawings, in which Figure 1 is a side view of a ball tube mill, partially sectioned on a central longitudinal vertical plane;
Figure 2 is a side view of a portion of the hollow cylinder thereof partially sectioned on a like plane;
Figure 3 is an end view of a portion of the mill;
Figure 4 is a transverse sectional view of the mill taken on a vertical plane corresponding .to lineA 4-4 of Figure 1;
Figure 5 is a side view of a fragment of one of the partitions in the cylinder;
Figure 6 is a sectional view thereof taken on line 6-6 of Figure 5; and
Figure 7 is a sectional view of taken on line 7-V-7 of Figure 5.
The mill or machine illustrated b the drawings comprises a hollow cylin er 1, made of sheet iron (such as is used in Steam the same 1924. Serial No. 703,859.
boilers) or the like, and rotatablywmounted axially-horizontally on bearings 2 in which turn the cylinders hollow trunnions 3, through which trunnions is introduced into the cylinder the material 20 to be ground or pulverized, as crushed gypsum rock and the like, from suitable hoppers 4 at the cylinders opposite ends. Intermediate the closed ends 5 of the cylinder are positioned a pair of partitions 6, 7 spaced apart, as shown, by suitable struts 8. These partitions have. oriices 9 therethrough, for the passage, into the space between the partitions, of the material which has been ground or pulverized in the chambers 10 between between the partitions, so that said orifices will not become stopped or clogged by the material passing therethrough. The cylinder has orifices 21 extending through its sidewall from the space between the partitions, such orifices likewise extending through the band 16 which surrounds the cylinder to strengthen the same in its middle and oriflced portion and to sustain the wei ht of the material therein.
o conne the powdered product of the mill, a fixed member 17 surrounds the cylinder and has a chamber 18 surrounding its middle portion through which portion the orifices 21 extend, these orifices thus opening into said chamber. This chamber has at its bottom a vent 19 through which the finished product of the mill is delivered into a horif zontally disposed channel 30 furnished with a worm feed 31 rotated by the shaft 32 carryingl the gear 23 meshing with gear 24 on the worm feed shaft. t
A pair of circular flanges 25 surround the cylinder and extend into the chamber 18 on opposite sides of the orifices 21. rllhese flanges serve to additionally stren hen the cylinder and to keep the pulverize product issuino` therefrom more perfectly confined in said chamber. Diametrically opposite man .holes through the cylinders side wall and ius into its chambers 10, 10 respectively are shown closed by covers 26.
It will be seen that by the construction shown weight and floor space are economized and necessary parts are minimized; for, inasmuch as the two chambers 10, 10 of the cylinder discharge from the same orices 2l between them, only two trunnions for the combined mill are required, thus shortening its length and decreasing its weight, while the same power may be employed as if the chambers l0, 10 were in separate cylinders each having a pair of trunnions and being driven by separate means.
The invention being intended to be pointed out in the claims, it is not to be limited to or by details of construction of the particular embodiment thereof illustrated by the `drawings or hereinbefore described.
-I claim:
1. In a machine of the character described: a rotatably-mounted aXially-horizontally-disposed hollow cylinder having intermediate its ends spaced apart transverse partitions with orifices therethrough, and having vents through its side wall between the partitions for discharging the ground material from the cylinder.
2. In -a machine of the character described: a rotatably-mounted axially-horizontally-disposed hollow cylinder having` in its middle portion spaced apart partitions with orifices therethrough, and having a reinforcing band surrounding its Said middle portion and vents between the partitions e-X- tending through said band and the cylinders side wall for discharging the ground material from the cylinder.
In a machine of the character described: a rotatably-mounted axially-horizontally-disposed hollow cylinder having vents through its side wall for discharging the ground material from the cylinder; a stationary member surrounding the cylinder, having a chamber into which said orifices open and a discharge vent.
4. In a machine of -the character described: a rotatably-mounted axially-horizontally-disposed hollow cylinder having vents through its side wall for discharging the ground material from the cylinder; a stationary member surrounding the cylinder, having a chamber into which said orifices open and a discharge vent, the cylinder having radial flanges extending into said cham- "ber on the opposite sides respectively of said orifices.
In testimony whereof I have hereunto set' my hand at Grand Rapids, Mich., this 29th day of March, 1924.
ALFRED H. APTED.
