23,717. Baumann, R. Nov. 28. Roller-and-ring mills for cements &c. The vertical shaft C carries a disc D above which are placed the rollers E. The roller spindles I extend through slots in the disc, and are carried in arms H pivoted at G on the lower face of the disc. This construction divides the mill chamber into two parts, in one of which the grinding is effected, while the other contains the joints of the working parts. A current of air, blown in at M, prevents the descent of the material under treatment into the lower compartment, and carries away the sufficiently-reduced particles by the outlet N.
