Studies on dense phase pneumatic conveying of bulk solids
Dilute phase pneumatic conveying involves higher erosion study includes up-gradation of the existing setup with
of pipelines, power consumption, high particle attrition advanced instrumentation and detailed investigations on
etc. The dense phase operates at a lesser conveying various flow and operational parameters for dense phase
velocity. Hence, it can overcome the above problems, pneumatic conveying of minerals/ores/industrial wastes
but it’s very sensitive to operating parameters like and powder samples like coal ash/ gray portland cement/
conveying air velocity, pipeline pressure drop, material sand/ iron ore etc. Scale-up will be attempted for power
characteristics etc. Also, computational methods are not plant fly ash through an appropriate Machine Learning
mature enough to simulate dense phase accurately. The algorithm.
