Direction parallel to the weld crack, a certain angle the axis of the steel pipe, typically between 30-70 .
The disadvantage of this and many other gravity counter-current classifiers is the presence of a laminar velocity profile in the gas, a large cone angle leading to flow separation and eddy formation, settling out of fines due to the retarded velocities near the walls, and the noise of vibrators necessary to prevent particle adhesion to the ...
Jun 01, 2016 Compared with other classifying machines, the disadvantages of hydrocyclone are below 1. Since slurry is processed with high-velocity motion, cylinder, spit, feed pipe and other parts are weared quickly. Meanwhile, these wear bring losses to power. 2. Feed pressure, feed concentrate and feed particle size will influence classification index ...
Jun 01, 2016 Hydroclassifiers are solving the most difficult fine sizing and desliming problems by combining high metallurgical efficiency in a rugged, well- built machine to accurately fulfill the exacting conditions required.
