Now, Raymond mills at current are beneficial for energy saving and environmental protection. They have high processing capacity, high separation efficiency and low energy consumption. It's expected that they will be more popular. Materials:Limestone, gypsum, coal, calcite, barite, dolomite, talc, calcium carbonate, kaolin, petroleum coke, etc.
States has far more coal than gas and petroleum (compare Figures 7-1, 8-1 and 9-1). This suggests that, when supplies of gas and petroleum become scarce, it would be possible to turn to coal as our major fossil fuel energy resource. How long could we rely on domestic supplies of coal? There are many uncertainties involved in making such an ...
