双向排料筛，顾名思义就是可以从两个方向进行排料。该筛主要是针对动力煤选煤厂的筛分工艺流程而提出的。一般的动力煤选煤厂的选煤工艺流程如图１所示。完成上述工艺流程在选煤厂厂房布置上，一般需要两层楼的空间，基建造价较高，并且原煤脱水和分级在设备上也需要两台振动
Two-way discharge sieve, as the name suggests is from two directions for nesting. The screen is mainly for the coal preparation plant screening process proposed. General thermal coal preparation plant coal preparation process shown in Figure 1. Completion of the above process in the coal preparation plant layout, generally require two floors of space, higher capital costs, and dewatering and classification of raw coal equipment also requires two vibration
