The innovation relates to a mixer for grain and additives materials for the production of a desired Vlehmlschfutter, whereby A mill is connected to the mixer, to which the grain and the additives are fed and the mixer aas one The upper mixing chamber and the lower task of the mixing components consist of the mixing chamber from bottom to top through a central one Conveyor screw are fed in a circulating manner.

On farms wlr4 for the production of an MIs ehfuttere In general, the procedure was such that the company aa grain was ground in a mill and then mixed with additives, e.g. Protein substances such as fish meal, So.1 ashrot, trace elements and the like. depending on the type of feed mixing desired in a mixer mixed and then a reservoir z. B. by a sponsor is supplied, from which the feed mixture is then removed as needed will. It now often happens that the mill is direct can be connected to a storage container for the compound feed. or that mills are used that have a pneumatic delivery line have through which the feed is fed to a storage container

can be. In such cases it is not advisable to connect a mixer downstream of the mill, as this again requires conveyor systems. Instead, it is advantageous to proceed in such a way that a mixer is connected upstream of the mill, to which the grain and the next The necessary additives are supplied and the grain is then ground in the mill with the additives flowing through and then is fed from the mill directly or with pneumatic conveying capacity of the mill to a storage container.

Mixers for feed are generally constructed so that the Grain ground in a mill with the additives of a desired cattle feed mixture is fed to the mixer below and by a screw from bottom to top, circulating several times, to a mixing chamber and finally, after mixing, over a lower side outlet of the mixing chamber is removed and fed to a storage container by means of a pneumatic conveyor will. But if the mill can now be arranged in such a way that the grist can drain directly into a storage container! or if the mill has a pneumatic conveying line, it would be impractical to connect the mill upstream of the mixer vice versa, proceed so that the mill for grinding the grain is connected after a mixer. However, this brings various Problems with itself, because then the grain must with the additives, such as. B. fish meal, meal, trace elements or

Like. Before the grain grinding mill are mixed. In mixers of the known type, the rate of descent is on the {Inner circumferential walls of the mixing space generally largest fend least near the central conveyor tendon, like

It is used to mix ground and powdery feed ingredients desired 1st.

But as well as grainy ingredients, such as grain with other meal or powdery ingredients are to be mixed, 1st this distribution of the sinking velocities in the niche is extremely unfavorable and there is not a mixing but a separation {of the components, as the individual components of the to be manufactured Fodder in the mixer sink in vertical ring layers, so that essentially only the rapidly sinking grain is fed into the mill and only then the other components with which the components emerge from the mill completely unevenly mixed.

Dm in this direction to remedy the situation and dee the mill To feed grain to be ground with the already fine remaining components of a cattle feed in a constant mixture proposed according to the innovation that in: the mixer mentioned at the beginning, the central screw conveyor in the lower part of the mixing room surrounded by a truncated cone jacket, whose upper, shorter peripheral edge is adapted to the circumference of the screw and whose Lower circumferential edge with the container wall narrowing conically to the screw a circumferential slot to the screw and the outlet to the mill. With this it is achieved that

Stocktelle occurs and finally after repeated circulation over the outlet of the mill are fed, in which the grain is ground, with the remaining fine feed components simple run through the mill without affecting the grinding performance the mill is noticeably adversely affected, as tests have shown.

The mixing device to be switched in front of a mill according to the innovation will now be explained, for example, with reference to the drawing, on it a vertical schematic section through the mixer 1 shown in Figure 1, while Figure 2 shows an end view of the mixer spout.

The mixer consists in a known manner from a mixing space 1, the is closed at the top and provided with a fitting 2 and whose peripheral wall 3 merges into a truncated cone wall 4, to which a cylinder tube 5 is connected, the lower end of which opens freely into a feed hopper 6. In the bottom of the feed hopper 6 and in the lid of the waste chamber 1 is one of the inner circumference of the cylinder tube 5 adapted in the diameter of the screw conveyor 7 stored, which is set in circulation via pulleys 8 or the like, and which are fed to the feeder 6 Mix components in the mixing chamber 1 calls, in which the Misohbestandtelle sink from top to bottom and the auger ! Be fed back above the cylinder tube 5, so that the mixing components are repeatedly circulated for thorough mixing {same can be done. Venn the mixture components of ground grain and fine or powdery additives exist, the rate of descent is 9 on the inner one

Circumferential wall of the nlschraumes 1 larger than near the screw conveyor 7, as indicated by arrows 9 and 10 1st. A mixture is then created by the circulation process of the one after the other the feed hopper 6 to be supplied niche components.

And now but cereal with fine or additional pulverförmlgen '^ t

substances are to be mixed, the rate of descent of the Cereal grains on the inner circumferential wall 3 of the Nlschraumes very large, and this grain then no longer mixes with the other fine or finer grains that sink into ring layers Additional ingredients. There is then no longer a niche of grain with the fine components, but a segregation, which is evidently due, above all, to the fact that the angle of repose for cereal grains is very much smaller than the angle of repose of fine or powdery components.

In order now to achieve according to the innovation that grain is perfect evenly with the other finer components of a Mixed feed mixed in the niche, the procedure is that the Screw 7 la lower part of the Nlschraumes is surrounded by a truncated cone jacket 11, the upper shorter peripheral edge of the Screw circumference adjusted 1st. The lower peripheral edge lla de « downward widening truncated cone jacket 11 bluet with conical cur screw 7 narrowing container wall circumferential passage slot 12 su of the Seaneckentell Oberaal jdes cylinder tube 5 and su that leading to a NOaIe 13> and thereby it is achieved that the

on the inner circumferential wall of the mixing chamber 1 and increased towards the screw 7, as indicated by the arrows Ik and 15 1st. The mixed components fed to the feed funnel, namely the grain and other finer additives, are now mixed with one another by circulating several times in the mixing chamber 1 with the outlet 15 closed.

Jstumpwandung 4 is formed, is supported by the fact that the j screw 7 is rigidly connected to agitator arms 16 'at different heights, the procedure advantageously being such that the ! The lower pipe arm is located approximately at the level of the outlet 13. To

! Multiple recirculation of the mixed components is flawless uniform mixture composition is achieved, and this mixture is now via the openable outlet 13 a Mill, in which the grain in the mixture is ground, while the finer ingredients are simply passed through the mill with walking through. A steady one then emerges from the mill Mixed feed from which is fed to a directly connected storage container or which in the event that the Mill having a pneumatic conveying line via a pipeline can be fed to any storage container to be set up.

Ub to avoid that there are bridges of the mixed components in the mixing space 1 form, the procedure is that of the mixing space winding to the truncated cone jacket 11 on the circumference distributed from the outside inward and downward sloping rods 17, which this bridging impede. The truncated cone jacket 11 is otherwise through
