Abstract

In order to meet TISCO’S demand of additional coking coal at the end of the second Five Year Plan it has been decided to install a central washery at Bhojudih, which would receive its raw coal supply from the collieries dispatching coal through Bhojudih railway marshalling yard. Depending on the present output from the different collieries located in this region, the normal capacity of the washery has been rated initially at 250 t.p.h. with due provision for future expansion to 500 t.p.h by incorporating some additional units and/or sections. Since the supplies are to be drawn from seams with comparatively superior wahsability characteristics, it has been possible to plan a fairly simple layout with no provision for recovery of middling. The design takes into consideration any possible size variation in the feed coal and also some reasonable fluctuation in the yield of washed products. The present paper relates to the washing scheme to be followed and the general description and specification of some of the major sections of the washery, such as raw coal handling: storage and pre-treatment: washing ; slurry treatment; products loading; medium preparation, recovery and control; centralized control; buildings; control laboratory; etc. indication the relative advantages of some of the units wherever possible. Some idea of the extent of the coast involved in the various sections of the washery is also given.
