Little abrasion wear, Long service life

Based on 30 years of development experience of grinding equipment, LM Heavy Industry produced LUM Series Superfine Vertical Roller Grinding Mill to make ultra-fine powder. The grinding roller doesn't contact with millstone usually, which makes abrasion little and service life longer.

Applications: Superfine dry powder of none-metal ores such as calcite, marble, limestone, coarse whiting, talc, barite and dolomite and so on.

Iron Smelting 101 Harald the Smith

An ancient method of iron production, which consists of gathering iron ore and then smelting it in a clay shaft full of burning charcoal. The result is called a ‘bloom’ a spongy mass of white hot iron, which then needs to be hammered, folded and welded until it is refined into a usable ingot. Fire, earth and sweat giving birth to metal
