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.

Asphalt

About 40,000,000 tons were produced in 1984. It is obtained as the "heavy" (i.e., difficult to distill) fraction. Material with a boiling point greater than around 500 °C is considered asphalt. Vacuum distillation separates it from the other components in crude oil (such as naphtha, gasoline and diesel). The resulting material is typically further treated to extract small but valuable amounts of lubricants and to adjust the p

The Unique Pitch Lakes Of The World WorldAtlas

17/02/2021 Asphalt lakes or pitch lakes are tar pits that form when a type of petroleum called bitumen is forced from underground up to the Earth's surface. Usually occurring along fault lines, the bitumen pools at the surface and the lighter elements vaporize, leaving a pool of natural asphalt. Mining for asphalt and tourism are important economic activities associated with such lakes. The world's five

Polyfunctional Modifiers for Bitumen and Bituminous

The use of bitumen as film-forming base in asphalt materials is justified primarily by the fact that the rate of diffusion of water into the bitumen is 0.83 · 10 −15 –1.66 · 10-15 kg·m/(s·N) ; this causes low solubility of water in the bitumen. As mentioned above, the degree of adhesion between the bitumen and the stone material depends on the chemical nature of the components and
