Appts. to test readiness of heat treated coal - has receptacle in form of sleeve open at both ends secured to bracket fixed on shaft

摘要

The coal readiness is evaluated in terms of time as a span between the moment of exerting pressure on a test sample of heated coal and that of the beginning of the coal swelling and has a receptacle for accommodating a test sample taken from a stream of coal, and a plunger associated therewith. The receptacle comprises a sleeve open at both ends which is secured to a bracket fixed on a vertical shaft rotatable by a drive means provided therefore. The part of the shaft which carries the bracket is placed within a casing which has a coal feed pipe on its top and a coal disposal pipe on its slant bottom. The coal feed pipe is located at a point just over the path of the receptacle rotation.
