Determination of element affinities by density fractionation of bulk …
To determine trace element affinities in the coals studied, density separations were carried out following the method of Querol et al. [21]. Six to seven density fractions between <1.3 and >2.8 g/cm 3 were obtained from the bulk coal samples by using heavy liquid mixtures of bromoform, tetrachlorethylene and xylene.

Effect of bulk density of coking coal on swelling pressure
The results showed that when the values of density increased from 0.85 ton/m (3) to 1.05 ton/m (3), for the Laowan gas coal, swelling pressure variation and even the maximum value changed slightly. The swelling pressure was 3.63 KPa when the density was improved to 1.05 ton/m (3); for the Xinjian 1/3 coking coal, the values of swelling …

ISO 23499:2008 (en), Coal — Determination of bulk density
This International Standard provides description of a cone procedure for determining an uncompacted bulk density of crushed coal less than 37 mm in size, such as is charged into coke ovens. 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.
Ore, Rock & Aggregate Screening (Complete Guide)
A-Z Guide to Screening Ore, Rock & Aggregate. A simple definition of a "screen" is a machine with surface (s) used to classify materials by size. Screening is defined as "The mechanical process which accomplishes a division of particles on the basis of size and their acceptance or rejection by a screening surface".
Vibrating Screen Capacity Calculations
The material velocity of a circular vibrating screen can be calculated from the corrected theoretical speed of the product formula written below. Example: Determine the material velocity of a screen vibrated at 900 RPM with a 12 mm stroke and 20° degree inclination angle. To calculate the bed depth of the material, the following formula is used.
