undersize powder

By means of testing the purifiers 1P and 2P, changes in the flow rate, ash content and size distribution of the throughs and overtails of each of the purifier decks and sieve sections were primarily studied under the relatively steady conditions of raw material, flow rate, air volume and mesh, and a flow balance sheet of the purifier stocks separation was obtained.

通过对清粉机 1P和 2P的测试 ,探索在原料、流量、风量、筛网相对稳定的条件下 ,清粉机各层、各段筛下物与筛上物的流量、灰分和粒度分布变化 ,首次获得了清粉机分级过程中的流量平衡表。
