Akabira Colliery installed a coal preparation plant in 1941 and started itsoperation in 1943.At the beginning, its capacity was only 210t/h, and after amalgamating withKami-Utashinai Colliery, it was raised up to 280t/h.With the increase of coal output, we studiedan advanced technology on coal preparation, and completed the installment of conspicuous coalpreparation plant.<BR>At the present intensified rationalization, many parts of the plant have been improved and wellequippedsuch as coal preparation system using Takabu-jig, applications of the automatic refuserejector, the resonance screen for clean coal dewatering, Humboldt-centrifuge and Konturbex.The profit obtained after rationalization is expected to have attained to the sum total of about 600million yen.
