I UNITED STATES PATENT OFFICE.
KARL FAHLAND, OF IDESSAU-GROSSKUHNA'U, GERMANY.
DRUM-MILL FEEDER.
Application. filed July 15, 1927, Serial No. 206,105, and in Germany February 18, 1927.
My invention relates to drum mills of all types. In such mills the fitting together of the stationary inlet hopper and the rotating drum of the mill oll'ers great ditliculties. It
has been proposed to provide the inlet hopper for feeding the material into the mill with a hub projecting into the hub of the drum. In this way it was however impossible to obtain the necessary tight fit between both parts.
For this reason it was up to 110w necessary to place so-called flour collectors below the gap between the inlet-hopper and the millcollar in order to catch the material dropping out.
5 My invention eliminates these disadvantages entirely. I attain. this result by providing in the stationary feeding hopper for introducing fresh material into the revolving drum a special guiding chute of iron which at its lower end projects far into the hub of the mill drum and may be replaced very easily. The great advantages brought about by such a sheet iron lining or guiding chute is obvious.
With such a device it is possible to introduce substantially the entire quantity of material into the rotating mill, without fine particles being forced out through the joint, inasmuch as the inlet chute projects far into the mill and the material fed is at once engaged by the conveyer blades. The Worn out charging chute may easily be replaced at low cost, without the feed hopper being af tli'ected at all.
ing the material.
For a smooth guidance of the material. there is provided within the hopper e and a separate sheet iron lining or chute f which can be easily replaced and projects with its lower end 9 far into the hub or collar 0 of the mill 5.
The material introduced. is at once engaged by the blades d and conveyed into the mill. When the chute is worn out it can be replaced without dilliculty and at small expense without affecting the hopper.
I claim In combination with a drum mill, a feed hopper merglng 1ntoa feeding chute for the material lntroduced into said feed hopper, an
easily exchangeable lining in said feeding chute, said lining promoting far enough nto said mill to prevent material trom falling into the joint between the mill and said feed hopper.
