矿石的破碎随着开采深度的增加,矿石硬度越来越大,因此,需要采用效率高的破碎设备。在破碎工序,引进了环辊破碎机,它能将来自一般破碎机的750毫米的大块,破碎成-10毫米的粒度。为了处理较硬的矿石,并采用了新式脱泥砂的振动筛取代转筒筛。重介质选矿红柱石晶体的比重(3.1)与围岩的比重(2.7)约差0.4。 Broken ore As the mining depth increases, the ore hardness is increasing, therefore, the need to use efficient crushing equipment. In the crushing process, a ring roll crusher was introduced which crushed a 750 mm chunk from a typical crusher to a particle size of -10 mm. In order to handle harder ores, a new descaling vibrating screen was used instead of the rotary screen. The ratio of heavy medium toalusinite (3.1) to surrounding rock (2.7) is about 0.4.
