Jul 18, 2013· Sometimes the classifiers are bypassed in order to supply coal to service bunkers continuously. This causes deterioration of coal crushing and in turn coke quality. Addition of an oil-water emulsion to the coal blend reduces the angle of repose and improves the bulk density of coal charge improving its flowability.

Glossary of Mining Terms - Coal Eduion
Angle of dip - The angle at which strata or mineral deposits are inclined to the horizontal plane. Angle of draw - In coal mine subsidence, this angle is assumed to bisect the angle between the vertical and the angle of repose of the material and is 20° for flat seams. For dipping seams, the angle of break increases, being 35.8° from the
Effect of size segregation on coal bulk density in the
modem metallurgical industry, coke is still the primary raw material, but the coke quality required is now much higher than before. It . is well known that the quality of coke depends to a large extent on the bulk density of coal charge that can be obtained in the coke oven. For example, it
Prediction of contact angle of coke-pitch system from raw
contact angle is measured from the video images using FTA 32 software [1, 25-29]. Inert nitrogen atmosphere is maintained during the experiment. Contact angle smaller than 90 indies that the solid is wettable by the liquid. The lower the contact angle is, better the wettability is. The details of the experimental system and the
EXPERIMENTS ON THE ANGLES OF REPOSE OF GRANULAR …
Two angles of repose are measured by this method. The critical angle of repose (ac) , is defined as the angle through which a mass of granular material can be rotated before it fails by avalanching, and the angle of rest (a R) , is defined as the inclination of the slope after avalanching has ceased.
TRACEABILITY OF RAW MATERIALS IN SILOS IN AN ANODE …
In an anode plant, coke and pitch are purchased from different suppliers. Also, the quality of coke the same supplier can from vary depending on the petroleum crude and calcinations conditions used . They are then stored in silos and used when required. Thus, different consignments of coke/pitch may rest in a silo at a certain point in time.

Top 27 Chemical Engineer Interview Questions and Answers
10. What is the angle of repose importance in the chemical industry? The property of particulate solids mentioned as an angle of repose. When a bulk solid poured into a flat surface, a conical pile developed. The angle that developed between the pile edge and a flat surface called angle of repose.
Study of the Wettability of Coke by Different Pitches and
Oct 06, 2016· The properties of coal tar pitch, which is used as the binder material for carbon anode production, strongly affect the anode properties. Pitches have significant differences in their chemical compositions depending on their origin. In this study, four different coal tar pitches and their blends were studied with the aim of understanding the wettability of a calcined petroleum coke by pitch
Gravel placement techniques - PetroWiki
This occurs because the angle of repose has been exceeded, and gravity becomes a more dominant force that causes a gravel dune to form in the completion interval. To ensure propagation of the dune, the ratio of the washpipe outside diameter (OD) to the screen inside diameter (ID) must be larger than 0.70.
