According to the increasing output plan, construction of the new coal preparation plant of 400 tons per hour in capacity had been projected at Mitsubishi-Bibai Colliery, Hokkaido. The new plant construction was started in February 1960 and was put in operation in June 1961. For the purpose of high efficiency in cleaning and accurate stability in coal quality, the new plant adopted Drewboy dense-medium separators for, coarse coal and a feldspar bed-jig for fine coal.
This paper describes chiefly the fundamental elements and some problems involved in the design of the new plant as well as its outlines.
