Coal - Determination of bulk density of coal as it is handled in industrial practices
This document specifies a cone procedure for determining an uncompacted bulk density of crushed coal up to 45 mm nominal top size, as it is handled in industrial practices. It focuses on the uncompacted bulk density of coal resulting from flowing the material into a measuring container (box) in the absence of compacting forces. The determination of the bulk density of coal charged into coke ovens is a typical example.
This document also provides a method for determining the bulk density of dry powdered coal at 63 micrometres for boiler or utility application. It does not cover the determination of bulk density of coal in storage piles.
