Focus on particles | TRUMPF

particles are trapped efficiently. Otherwise damp, fine particles may agglomerate and form a sludge on the interior of the exhaust vent. If an exhaust vent is used, it should be straight and of minimum length. It should be able to withstand an internal explosion pressure of at least 100 psi, as recommended in NFPA Standard No. 484.

1. Introduction Pelletization is an agglomeration technique, beneficial with finer iron ores over other agglomeration processes .Pellet making involves balling of fine powders and dusts with addition of moisture (8.5-9.5 %) and binder in a rotating disc or drum to produce green pellets and subsequently indurating the same on a moving grate to produce fired pellets[1].Drum pelletizer is used ...

how to grind iron ore fines particle

A process for producing a balled coal product from coal fines involves mixing a bridging liquid with coal fines and agitating the formed mixture in an aqueous medium to cause agglomeration of the coal particles. The coal particle agglomerates are then at least partially de-watered and fed to a balling device, together with a balling nuclei of coarse coal particles and binding oil to form a ...
