目前,重介旋流器普遍用于选煤,其洗选粒度上限约1—1/2英寸,洗选粒度下限约28网目。下限28网目是根据脱介振动筛对最小颗粒的有效处理情况而作出的。重介旋流器的入料一般是予先脱除-28网目级的煤泥。这就需要大面积的脱泥筛,并需加大量的喷水,筛面和喷水量应视-28网目级含量而定。 At present, the Dense Medium Cyclone is generally used for coal preparation. The upper limit of the washing particle size is about 1-1 / 2 inch and the lower limit of the particle size is about 28 mesh. The lower limit of 28 mesh is based on the effective removal of the smallest particles from the de-indexing shaker. Dense cyclone feed is generally removed prior to -28 mesh grade slime. This requires a large area of ​​desilting screen, and the need to increase the amount of water spray, screen surface and water spray volume should be -28 mesh content level may be.
