Ultrafine Grinding Mill Made in China LinkedIn

Ultrafine grinding mill is a type of milling machine that has recently gained popularity in China. This type of grinding mill is designed to produce extremely fine powders or micro-sized particles.Magnetite sample was obtained from Divrigi Iron Ore Concentration Plant (Turkey) in the form of magnetite concentrate 85% −45 μm, assaying 97.6% Fe 3 O 4. This material was further ground in a ball mill to produce enough ultrafine material. The ground material was wet screened at 53, 45 and 38 μm.Recovery enhancement of magnetite fines in magnetic separation
