Effect of particle size on flowability of Lithium hydroxide powder

Abstract In order to improve the flowability of lithium hydroxide powder, powder in a company was selected under conveying condition. The degree circularity used quantitatively characterize micro-morphology and influence particle size on studied by angle repose method, HR method Carr index method. results show that gets better with increasing size. But fine particles (≤ 100μm) is poor, while medium (100~200μm) coarse (≥ 200μm) good. Based experimental results. It suggested inclination silo should be designed no less than 50 0 content 100μm controlled efficiency powder.
