Improvements brought to the rotary crushers with travelling free bodies, more particularly to the rod mills.
FOR INVENTION AS AFRICAN AND MALAGASY INDUSTRIAL PROPERTY P. 887 Yaounde (Cameroon) Patent № 00121 the O. 00 the m ^ P.I.. THE V * Requested 29 April 1964 to 11 hr 45 min. to IO.A.M.P.I. (G.P. no. 50,085) by the poll worker Geological and mining, residing in France (decrees of 23 October 1959). Issued 15 January 1966, published at The invention is related to the genus of mills those which comprise a rotating cylinder, a sensing axis - telling a horizontally, which contains free rolling bodies designed for compressing between them and the inner surface of said cylinder products introduced therein; and more particularly, because it is in their case that its application seems to be most need of interest, but not exclusively among these mills, those in which said bodies are bars free cylindrical. It aims at rendering such these mills they eliminate the "sliminess", it is to say that the dimensional electronic - identifiable conclusions of the majority at least milled products do not extend below a certain limit. It consists, primarily, in the crushing of the genus in question, providing on the sidewall of the cylinder, exhaust holes for ground product, these holes are formed preferably by the meshes of grids arranged in openings in said wall, in which case the openings are advantageously distributed along the length of the cylinder. It consists, except for this arrangement key, in certain other arrangements which are used pre - férence simultaneously present and it will be more explicitly spoken hereinafter. It is directed more particularly some embodiments metadata Application - the cation, as well as certain embodiments, of the tail - said arrangements; and it more particularly targets still, and as new industrial products, the grinders of the kind in question having applica - action of these same arrangements, as well as the elements and special tools specific to their establishment. And will, in any event, be clearly understood by means of the complement of description that follows, as well as of accompanying appendices, which complement and drawings are, of course, given mainly as an indication. Figure 1, of these drawings, shows, in elevation laté - ove, rod mill established in accordance with the un - and attaches. Figures 2 and 3 show the same mill seen the res - from the right and from pectivement the left of Figure 1, certain parts being cut to Figure 2. According to the invention and more especially according to that of its modes of application, as well as according to those embodiments of its various parts, to which it seems the need to tune the preference, volunteering it establish a rod mill, would take as follows or similarly. In the mill as a whole, put together in any appropriate manner such that it has a rotating cylinder 1 for receiving the material to be ground and containing cylindrical bars free 2, the dimensions of the cylinder being determined depending on the nature of the treated products and the required flow rate of the mill. For supporting and rotating the cylinder 1, this can be done on two pairs of friction rollers 3 and 4, the rollers 3 arranged on a same side of the cylinder being driven, via their common shaft 5 and a reduction gear 6, by a motor 7, while the rollers 4 may be idle on their axes aligned. The rollers 3 and 4, located in the same transverse plane, can be engaged in the groove of a gutter-shaped belt 8 which prevents the cylinder 1 move parallel to its axis. Alternatively, the rollers 3 would be idle on their axes as the rollers 4 and the cylinder 1 can be rotationally driven by a ring gear coaxial with said cylinder and provided with a pinion driven by the motor 7. In yet another embodiment, instead of relying on rollers 3 and 4, the cylinder 1 could be carried by a shaft mounted on bearings and driven by the motor 7 by means of a reducing agent. Finally, there is a loading device for the cylinder, the device may include providing a door 9 as one of the funds of the barrel to a batch feed or into a chute or similar device capable of introducing, continuously, the products to be crushed into a central opening 1,025,219. Rod mills. BUREAU DE RECHERCHES GEOLOGIQUES ET MINIERES. 4 Aug. 1964 [July 25,1963], No. 30942/64. Heading B2A. A rod mill comprises a rotating cylinder 1 whose longitudinal wall is provided with pockets 14 of depth a at least equal to the maximum size of the particles to be ground, so that, in operation, the particles rest uncrushed in the pockets and are released at a point where they will fall ahead of at least some of the cylindrical grinding bars, 2 in the direction of rotation of the bars. The depth a may be adjusted by a shim or wedge 16, the number of pockets is determined in accordance with the nature of the product to be ground. The bottoms of the pockets 14 include screens or gratings 11 in openings 12 in the wall 10 of the cylinder, to permit outlet passage for ground material, and these openings are distributed in echelon formation along the cylinder. Drive is affected by motordriven rollers 3 and rollers 4 disposed in grooves at the ends of the cylinder, or by a toothed ring- gear and pinion. Material is loaded through a door 9 or via a shoot and trunnion arrangement (not shown). 1° is provided, on the side wall of the cylinder, exhaust holes for ground product; The aforementioned holes 2° is formed by the mesh grids placed in openings formed in said wall; The abovementioned 3° is distributed openings along the length of the cylinder such that at least one opening is in any cross section of the cylinder, by a plane perpendicular to its axis; 4° allowed by the cylinder carrying said belts running resting on rollers and in arranging these belts beyond the level interior partitions and limiting the working volume of the cylinder.
