JOHN J. czannv, HENRY n. WHITLEY, AND MICHAEL xnnosnn, or wnsr ALLIS,
WISCONSIN.
ATTRITION-MILL SEPARATOR.
Application filed November 9, 1923. Serial No. 673,727.
To all whom it may cmwern:
'Be it known that we, JOHN J. CzAREv, HENRY H. WHITLEY, and MICHAEL KRnUsER, citizens of the United States, residing at 6 West Allis, in the county of Milwaukee,
State of Wisconsin, have invented a new and useful Attrition-Mill Separator; and we do'thereby declare the following to be a full, clear, and exact description of the invention,
10 such as will enable others skilled in the art to which it appertains'to make and use the same.
The invention relates to separators for attrition mills, and has for its object to 1 provide a devic'e of this character interposed between the feed hopper and the attrition mill disc whereby foreign matter, for instance nails and stones, will be separated from the material passing through the device, there- 20. by preventingl fires, incident to foreign matter passing t rough the attrition mill disc, or damage of the disc.
A further object is to provide the separator adjacent the feed hopper with an ad- 2 justable slidable door whereby the amount of material fed into the separator may be regulated. I v
A further object is to provide deflecting plates in the separator for deflecting the maround and the foreign matter therefrom. lso to provide a compartment into which foreign matter collects and from which it may be dischar ed as desired.
With the above and other objects in view '35 the invention resides in the combination and arrangement of parts as hereinafter set forth,-shown in the drawing, described and claimed, it being understood that changes in the precise embodiment. of the invention may be made within the scope of what is claimed without departingfrom the spirit of the invention. In the drawing Figure '1 is a vertical sectional view 4 through the feeding mechanism of an attrition mill, showing. the separator applied 'thereto.
Figure 2 is a rear view of the separator. Figure 3- is a top plan view of the separator, parts being broken away to better show the structure.
Referring to the drawin ,the numeral 1 designates a conventional orm. of attrition mill and 2 rotatable discs, between which material to be ground is fed and sucked in the usual manner through the chute 3. Disposed on the upper end of the chute 3 is a substantially rectangularly shaped casing 4: of the separator, which casing is held in position by means of a link connection 5 with the attrition mill casing 6, and superimposed on the casing 4 is the feed hopper 7, into which material enters in its passage to the attrition discs throu h the separator. Hopper 7 is provided wit% a conventional form of mixlng drum 8, which is driven through gears 9, pulley 10 and the belt 11, of which structureis of a conventional form. Slidably mounted in a U-sha ed guide 11 disposed between the hopper and the casing 4 is a horizontally disposed door 12, which door may be adjusted and moved for regulating the amount of material fed into the separator casing 4 and preferably towards the inclined plate 13 within the casing 4. The plate 13 deflects the material moving downwardly by gravity onto the inclined plate 14 and nails and stones will follow the course of the arrow a into the compartment 15 formed by the downwardly and outwardly extending plate 15 while the material being fed to the mill will follow the course of the arrow 6 into the compartment 16 and thence by suction into the chute 3 incident to the rotation of the discs 2. It will be seen that foreign matter such as nails or stones will be separated from the material before it enters the discs 2 and consequently fire or damage to the machinery is obviated. The outer wall of the compartment 15 is formed by a slidable door 18,
' which is preferably angularly disposed and when open allows foreign matter which has been separated from the material to drop into the discharge chute 19 and be discharged to one side of the machine.
From the above it will be seen that a separator is provided in connection with an attrition mill whereby foreign matter will be separated from material asit is fed to the discs and consequently fires are obviated. It will also be seen that foreign matter collected by the separator may be easily and quickly removed from the separated and discharged to one side of the machine, thereby obviating stopping of the machine for any length of time for removing the foreign matter from the separator.
The invention having been set forth what is claimed as new and useful is The combination with an attrition mill, a hopper carried by said mill, of a separator I interposed between the hopper and mill, a door interposed between the separator and hopper, a deflecting plate adjacent the inner end of the said door, an oppositely extending deflecting plate within the hopper below the first mentioned deflecting plate, a foreign material compartment communicating with said hopper and having an inclined base, between the u per end of which and the lower end of sai second deflecting late, 5 is a passage way for material to be retfiiced,
a door forming the outer wall of the for.-
eign matter compartment and discharge s outs for said foreign compartment and for t e separated material respectively. 7
' In testimony whereof we have signed our 20 names to this specification in the presence of three subscribing witnesses.
