are used to describe the ease of washability. The ROM Coal is crushed to four different top sizes namely, 75 mm, 25 mm, 13 mm and 6mm. On the basis of calculated IW it is observed that relative ease of washabiltiy increases with decrease in top size. The value of IW at -6 mm crushing size is 41.4 which confirm the ease of washing of this coal at this feed

Why Coal Reforms Are So Important For The Indian Economy

Costs : The estimated average cost for coal production (ROM coal, excluding crushing, sizing, transportation charges and all levies, duties, etc) is ~Rs 1,000 per tonne. Majority of the coal production is favourably placed with respect to cost of production except for about ~10% of overall coal production.

ROMJIG - MBE Coal & Mineral Technology

ROMJIG specifically developed for treating ROM coal for deshaling purposes. Earlier jigs were incapable of deshaling without crushing the ROM coal to a size less than 150 mm which incurred extra costs. But with the development and introduction of the ROMJIG this limitation was done away with and ROM coal with sizes upto 400 mm could be directly Deshaled with this machine without crushing.
