Improvements relating to the Manufacture of Thomas Powder from Thomas Slag.

摘要

63. Steinberg, H. Schulte-. Jan. 1. Manures.-Consists in the conversion of Thomas slag into powder by acting upon the slag in a closed chamber with steam at a suitable pressure. The apparatus may consist of a rotating drum. In the form shown in the Figure, a stationary vessel v is employed, into which are run trucks a containing a grating b for supporting the blocks of slag, and below this grating are a number of sieves c, d, e, of successively-greater fineness. The trucks are connected together, and one of them is connected with a rotating crank y which gives a reciprocating motion to the trucks, whereby choking of the sieves is prevented. The powder produced collects in the space f, and the unreduced pieces are subjected to a repetition of the process If a grating of wide mesh is employed, the sieves only need be reciprocated.
