选煤厂主要是由重力选和浮选组成的工艺流程,浮选是为精选煤泥而设置的。由于重力选煤方法在加工费用等方面,较浮选法具有更大的优越性,所以,实际上洗选加工作业尽可能用重力选来完成。一般认为跳汰深度是0.5毫米,且浮选粒度上限为0.5毫米时,浮选的生产指标也基本上能满足要求,因此,将浮选粒 The coal preparation plant is mainly composed of gravity selection and flotation process, flotation is set for the selection of slime. As the method of gravity coal preparation in the processing costs, etc., than the flotation method has greater superiority, so, in fact, as much as possible washing process selected by gravity to complete. Generally considered that the jigging depth is 0.5 mm, and the flotation particle size limit of 0.5 mm, the flotation production indicators are basically able to meet the requirements, therefore, the flotation grain
