Abstract
360,547. Portland cements. ANDREAS, A., 3, Engelstrasse, Munster, Westphalia, Germany. Sept. 1, 1930, No. 26111. Convention date, Sept. 2, 1929. [Class 22.] In the manufacture of cement &c. the wet or dry raw material, e.g. slurry is preliminarily treated before being fed to the kiln or sintering furnace by passage over a gas-permeable device through which the waste kiln or furnace gases pass thus abstracting the dust from the gases and utilizing the heat of the gases to calcine partially or wholly the raw material. The material is spread on or at the gas-permeable device in such a manner that its particles change their relative positions during their forward movement to the kiln. The fine grains or powder in the raw material may be screened off before the material is supplied to the gas-permeable device or the raw material may be first subjected to a balling, granulating or moulding operation or both screened and granulated. The Figure shows one form of apparatus in which the raw material from a hopper 4 flows to a rotary kiln 1 by gravity over a stationary screen 3 through which the waste gases pass to an outlet 5. The screen 3 may be adjustable as to inclination. Other forms of apparatus are shown and described. The Specification as open to inspection under Sect. 91 (3) (a) comprises an apparatus having a travelling grate delivering the raw material into the kiln through a rotatable shoot. This apparatus is not described in the Specification as accepted.
