1 Claim.
This invention relates to a new and improved rinding mill and has for one of its principal objects the provision of means for' delivering round material.
An important object of the invention is to provide a plate-grinding mill having its rotating plate carrying paddles for delivering the ground material to a vertical elevator.
Another important object of the invention is to provide a housing enclosed plate mill capable of grinding material and delivering it to the top of the housing smoothly and continuously with a minimum number of operating parts.
Other and further important objects of this invention will become apparent from the following specification and accompanying drawing, in which: n v
Figure 1 is a side elevation of the plate-grinding mill of this invention partly in section;
Figure 2 is a sectional view taken on the line 2-2 of Figure 1; and a Figure 3 is a detail view of the grinding plates of the subject invention, shown partly in sec- 1: on.
As shown in the drawing. reference numeral 6 indicates generally a base on whichis mounted a housing I substantially rectangular in shape and having a discharge spout 3 projecting from the top and sidethereof, as best shown in Figures 1 and 2. 4
Figure 2 depicts a flat belt cylinder pulley 9, which is adapted to be driven from a tractor having; a. power take-oi! or any other suitable driving means. The pulley 9 is integral with a I main shaft II, which acts 'to rotate a plate l2,
one of a pair of grinding plates. The rotating lar housing 23 having an aperture coextensive with the aperture 2| of the housing is at its lower end thereof. The tubular housing 23 is supplied with an exit opening 24 at the top thereof which is adjacent the spout 8. As best shown in Figure 2, the plate mill is supplied with an auxiliary shaft 23 Journaled within the housing I and running parallel with the main driving shaft ll. Mounted on the auxiliary shaft 26 are V- belt pulleys 21 and 23. A-V-belt pulley 29 keyed to the main driving shaft l l is in alinement with the V-belt pulley 21 on the auxiliary shaft 23, and by means of a belt 3|, impartsrotation from the main shaft II to the auxiliary shaft 26.
The vertical auger 22 comprises a central shaft 32, and a screw-type flighting 33 is wrapped around this central shaft 32 and welded or otherwise attached thereto.' The verticalv auger 22 has its central shaft 22 journaled within bearings 34 and 36, and at its lower end has an extension on which is mounted a V-belt pulley 36. The tubular housing 23 and the bearing 34 are supported by a bracket 31, which is attached at 36 to the housing 1. An annular flange 39 came auger shaft 32 is positioned immediately above the bearing 34, and it is quite evident that the bearing maintains the shaft and auger 22 in their proper vertical position. Directly above the flange 3! lies a disk member 4| which forms plate I! cooperates with a stationary plate l3, as
best shown in Figure 3, to grindmaterial bein fed to a V-shaped slot ll between the plates l2 and I3. The rotating plate I2 has a plurality of paddles l6 spaced radially outwardly from the outer periphery ll of the plate i2. It will be evident that as the grinding plate l2 rotates by application of driving means to the belt pulley 9, the integral paddles l6 also will rotate. The paddles l6 extend inwardly beyond a juncture ll of the Plates l2 and i3 and thus are adapted to receive material being ground by the plates and thrown centrifugally outwardly at this circular juncture 3.. An internal housing or partition I! surrounds the revolving plate l2 and its integral paddles l6, and, as best shown in Figure 1, -the housing I! has an aperture 2| adjacent a vertical auger 22.
the bottom of the tubular housing 23 in so far as it concerns the auger 22.
A V-belt 42 extends between the V-belt pu1-- ieys 23 and 33 and causes rotation of the auger v22 within the tubular housing 23. An arrow 43 indicates the direction of rotation of the auger. As material is thrown centrifugally outwardly between the grinding plates [2 and 'l3,'it comes within the path of the fan-like blades or paddles l6 and is thrown toward the vertical elevator in the form of the auger 22 because of the counter-clockwise rotation of the plate l2, as shown by an arrow M in Figure 1.
As best shown in Figure 2, the position of the vertical anger is slightly offset from a centerline or plane vertically passed through the paddles II. The shaft 32 substantially divides the flighting-33 into proximate and remote sections. An angularly disposed conduit 46 extends between the housing l9 and the vertical housing 23 and causes the material thrown from the paddle iii to be directed toward the proximate section of the flighting 33, and inasmuch as the ,auger is rotated in a counter-clockwise direction, as viewed in Figure 2, the ground material is adapt- The vertical auger 221s enclosed within a tubu- 33 ed to be scooped up and ed up dly wit the tubular housing II. This particular positioning of the vertical auger with respect to the vertical plane passed through the blades or paddies ll prevents any undue agitation. such as vwould be caused ii the material was fed broadside to the entire auger. Under such ,circumstances a section of the auger would be repelling the material fed thereto, and the remaining section of the auger would be accepting the material received and congestion would undoubtedly be created. It is quite important, therefore,- that the material delivered by the paddles II to the auger 22 bedelivered in such a manner that the lower section of the-auger flighting 33 receives all the material, and the direction of rotation of the auger will cause all thematerial received to be accepted by the auger and elevated in a smooth continuous manner. The feeding of the ground material to the exposed section of the augerflighting turning upwardly improves the action of the auger, and the material is lifted without undue agitation of the newly ground material.
"I'hedischarge spout I is relatively broad and in the central portion thereof has a rod 4'! journaled within its upper and lower portions and isinclined so that the lower end of the rod 41 is directed toward the housing I of the grinding mill. A diverter valve or paddle 48 is fixedly attached to .the rod 41 and is capable of shifting within the aperture 24 at the upper end of the tubular housing is. The lower end of the spout lar housing It, and thereupon ground material being elevated by'the auger 22 will be caused to exit throughvthe spout portion 53. If, however, the handle had been moved upwardly. the valve it would contact the lower side of the tubular housing extension 54, and ground material would be diverted to the spout section 52.
It will be evident that herein is provided a novel grinding mill which incorporates several important features to contribute to an eiliciently operating mill. Numerous details of construction may be changed throughout a wide range without departing from the principles disclosed v herein, and it is the intention that the'patent be limited only by the scope of the appended What is claimed is:
In a grinding mill comprising a rotary disc-like grinding member, blades projecting from the outer periphery of said grinding member, and a rotating auger positioned vertically and proximate an edge of said disc-like grinding member and in oflset relation from said blades, said vertical auger having a central axial shaft around which auger flights are wrapped, one side of said auger flight advancing toward said. grinding member and the otherside of said auger flight retreating from said grinding member, an enclosed passage between said blades and the lower retreating portion of said vertical auger flight for directing ground material to that half of the auger flight which is retreating from said grinding member, whereby groundmaterial is thrown by the blades through the pasage to the retreating portion of the vertically positioned armor for quick and conducive reception of the material being ground, and a discharge spout at the top of said auger.
