在选煤厂大型化发展的同时。双级(四齿辊)破碎机由于破碎比大、产量大且能够破碎中硬矿石,正逐步地取代颚式破碎机,在选煤厂的选前准备作业中起着愈来愈重要的作用。当确定了双级齿辊破碎机的总功率和总破碎比
In the large-scale coal preparation plant development at the same time. The double-stage (four-tooth roller) crusher is gradually replacing the jaw crusher due to its large crushing ratio, large output and capable of crushing medium and hard ores, and plays an increasingly important role in the pre-election preparation of a coal preparation plant . When determining the total power and total crushing ratio of double-stage roller crusher
