Effect of moisture on energy-size reduction of lignite

Jun 15, 2020· Reducing the moisture content of coal made the grinding easier. For samples with the moisture content equal to or below the air-dried level, the mass fractions of the top size fell to approximately 14.61% after 6 min of grinding, while for coal sample 1–3, the values were higher: 42.29%, 28.23%, and 24.73% respectively.

The Factors Affecting the Moisture of Coal from Coarse

Abstract :The coarse and fine coal centrifuges are widely used in coal preparation plants, it is characterized by large handling capacity, low production cost and easy maintenance. However, the coal preparation plant usually cannot control it well for the first time, which may makes the higher moisture of product or even causes the coal preparation plant out of production normally.
