Abstract

191,812. Testrup, N., Boberg, T., and Techno-Chemical Laboratories, Ltd. Oct. 15, 1921. Roller and disc apparatus.- Moist plaster material such as macerated peat, lignite, &c. is heated or dried while spread upon surfaces provided with grooves or channels, the sides of which are approximately parallel in the lower portion n<1> and flare outwards at the top. The grooves may be formed on the outer surface of hollow rotary drums heated internally by steam which may be obtained by compression of the evolved vapours as described, for example in Specification 149,055. A series of drums may be arranged to operate in multiple effect. The material may be fed between two drums with parallel axes, adapted to be adjusted both laterally and longitudinally so that the ridges between the grooves are over each other, or the ridges of one drum lie over or enter the grooves of the other. The material may be fed to a drum by a plain roller or by a plate held against the drum and is removed by rotary brushes or toothed scrapers. The grooves may pass round the circumference of the drum or longitudinally across the circumference.
