the the inni-an 'l'E il a8, 1525, Serial 1ro. llfl, and in Belgium Uctober 2, i924.
According to Figures 1, 2,13, 8b, 3C improved grindinp,` and mixing apparatus comprises a cylindrical jacket composed ot the upper part land lower part 2 assembled hy loolts 3 and loi-ming liront Wall Al and a rear Wall 5, which form in their turn hearings G and 'l' within which is mounted the driving shaft d provided with a pulley 9 disposed preterahly at the rear end ot the apparatus. rllhe trent Wall f1 is termed with one or more openings 10 permitting to look after and to lubrieate the inner movable parts oi the machine, Whereas the rear wall 5 is entirely open at 11 for the same and other purposes, the latter oit which will he described afterwards.
1lllithin the interior of the loiver part 2 of the jacket is lined a false-bottom 12 of especiallyT resistant material, as it is at this part ot the jacket, that the principal grind ing1 and mixing action taires place.
the I llpon the shalt 8 are keyed or otherwise rigidly lined a frontcross or equivalent plate 13 and a rear equivalent plate 1li. Each ot these plates is provided with tour or any other suitable number ot radial slots oit shalits 1'1", upon which is seated the correspending1 roller, a square section, only the end portions ofsaid shafts hein.01 ot cylindrii cal section, to permit said sha-its to freely rotate Within the hearings 35, these hear nge servingsimultaneously to guide the shatts 17 radially Within the plates 13, 11i. Vllhe particular construction of the guide bloc-ks 35a 36 and their disposition Within the ` grooved slots 16, 37 eliciently avoids janan ming of the shafts 17 as Well with respect to the rotary movement as with respect to the radial movementot these latter within plates 13, 14. ln the example shown in the drawings there are tour shatts 1'?, and upon these shafts are tired in any suitable inanner tour rollers 18. According to Figures 1 2, 3a, 3b7 3, these rollers are as follows:
(1) Two ot them are o'l identically Vthe same coniiguration and are constructed as represented in Figure 3a, that is to say their front side. portion is provided wit-h a. right-handed thread ot considerable depth and decreasing towards the rear side, this thread occupying approximately one half, of the total length of the roller, whereas their rear side halt' or portion presents a flat peripheral surface.
(2) The third roller (Figure 3b) is provided through nearly one halt et its length kand upon its front side portion with parallel circular grooves (no thread) whereas its 'rear side portion has a liatperipheral surface.
(8) The fourth roller (Figure 8C) is provided through nearly one halt' of its length and upon its front side portion with a fiat peripheral surface, whereas its rear side portion is provided with a lett-handed thread, the characteristics ot which are contrary to that of the threads ot the tirst mentioned runners.
All these runners are of the same dimensions and are of slightly conical section diverging towards the front side of the device.
The shaft 8, when considered in the sense of arrow m (Fig. 1) turns in a clockwise sense.
vThe jacket-part l is provided at its lowest front-side right-hand portion (arrow with a loading-hopper 22, a spray cone or sprinkler 23 withregulating cock 24 being dispose-d for instance within said hopper opposite to thev loading orice.
According to Figures 1 and 2 the rear side portion ol jacket 1, 2, 5, open at 11, forms anenlarged hollow portion 29, serving to receive a ring conveyor 27, 28 bolted to projections 26 of the rear platelit. The ring conveyer 27,- 28 cooperates with a sleeve conveyer 31, passing :trom the outside through an opening 30 in part 29 of the jacket, into said ringfconveyor 27, 28, and having a suit- Aably shaped beveled Vend portion, which comes into contact with the inner face of part 28 of the ring conveyer 27, and which is Vdirected in a sense opposite to the direction of rotation of the device.
rlhe operation is as "follows:
The rough materials to be treated, are delivered in any convenient manner to the hopper 22 andl are drawn within the interior of the 'device by the threaded portions of the first mentioned rollers 18. These threaded portions produce a preliminary and progressive disintegration and mixing ot the materials, carrying them simultaneously towards the rear end oi the device, thereby obliging them to enter within the path oi the fiat shaped portions ot said rollers, where the materials are denitely reduced to the desired state, the disintegrating action of the rollers being highly increased by the torsional action they produce due to their conical section. At the same tinie water is delivered under pressure through sprinkler 23, to give the. mass or material in treatment the desired degree et moisture.
The action o'l the second mentioned roller is essentially the saine that ol the lirsst mentioned rollers, with the dilllerence that. this roller, having no thread-shaped grooves, will not displace the materials towards the end portion oi the device.
The third mentioned roller serves to retard the displacement ott the materials towards the rear end of the device, due to its lett handed threaded endside portion, so obliging those parts oi the material wiich are not yet suiiiciently crushed and mixed, be entirely disintegrated and mixed by the whole roller system.
fis the materials 'treated as above pew-1 from the front to the rear end of the device, they are finally delivered at 25 (Figure l) within the ring conveyer 27, 28 and are troni here automatically directed to the :miei-de through the sleeve eonveyer 31.
rlhe device describe-d may be completed by a suitable system ot Scrapers as show in lli ures L1, 5 and 6, this depending principally from the nature of the materials to be treated.
According to Figures 4, 5 and (l, the iront side plate 13 is provided with one or nim-e scraper plates 38 se ving to wipe oil the niaterials entering trom the hopper 22, to the interior ot the device, propelling them simultaneously beneath the front side ends ot the runners.
Moreover, series of scraper plates may extend from the front side plate 13 to the rear side plate lll, between two successive. rollers. Such series ot scraper plates del fee Figures 5 and may be each pivotahli cennected, on the one hand, to a rod 42 which is rigidly secured to plates 13, 1li, and ou the other hand, to a rod L13 which is secured to plates 13. li in such a irzianuer, as permit ot being adjusted in its longitudinal sense, for instance by suitably fastening the nuts Li6 upon the threaded extremities oi" said rod 13. The plates 44 are inclined in such a manner as to cause. the materials to he treated to advance `from the iront side to the rear side ot the device. By more or less inclining the s ra-per plates Llll in the mentioned direction, the material in treatment will advance with a greater or lese speed. whereby the rate ot its disintegration and mixing may be controlled at will.
lf the given material,l for instance moulding sand, is to be treated at a more or less dry state, certain of the rollers 18 er all ot them may be sul'istituted by rollers aceordingi' to Figures in and T", composed of two discs-r, or cylindrical portions 18a with trininious 19 and ot longitudinal crushing hars i8 fill tlf)
or 18C of circular, ovoidal or other suitable cross-section, which are rigidly secured to said discs.
lt' the material to he treated is desired to advance with incre or less rapidity i''roni the front to the rear end ot the iiiachine, certain et the rollers l@ or 18o., Zi, o or all ol thein are substituted by rollers ldd (see lligure 8) having only parallel grooves ot sufficient depth and width.
According to Figures l and 5, the rear plate o ot the jacket is closed and there is a lateral downwardly inclined conduit el() tor the discharge oit' the treated material, For this purpose the rear side rotary plate 14e is also provided ivitlione or incre scrapers 33, which taire with thein the treated inaterial pressed out trein the pa` 'li ot the rollers, and cause said inatcrial to pass into conduit troni which it is directed outside, such discharge being assist-cd by cen ritugal torce and also by the pressure oli' the advancing material.
'lhe plate 5 inay be provided Wit-h a suppleinentary closable orilice ll for discharge, which normally reinains closed.
lt is evident that the device described inay be inodiiied in inany respects Without departing iroin the scope oi" the present invention.
