重介质粉与您分享:在生活中,我跌倒过。我在嘲笑声中站起来,虽然衣服脏了,但那是暂时的,它可以洗净。
影响弧形筛和脱介筛脱介效果的主要因素是原煤中的煤泥含量、喷淋水的方式和压力、合格介质悬浮液的流动性。煤泥含量是客观存在的,喷淋水的方式和压力受到人们的普遍重视。然而,重悬浮液的体积浓度过高也会造成严重的“筛上跑介”却未引起人们的足够注意。重介悬浮液的粘度随固相体积浓度增大而增大。当固相体积浓度达到35%时,粘度急速上升,当达到50%后,粘度接近最高值 ,重悬浮液表现为几乎没有流动性,成浆流状态,悬浮液透筛就会很困难,脱介效果很差。
Heavy medium powder and you to share: in life, I fell. I stood up in laughter, although the clothes are dirty, but it is temporary, it can wash.
The effects of arc sieve and sculping screen main factors de-medium effect is the mobility of spray water content of coal slime, the way and the pressure, the qualified medium suspension. Slime content is objective existence, and the pressure of spray water people pay great attention to the. However, the high concentration of heavy suspension will cause serious "screen run media" has not drawn enough attention. Of heavy medium suspension viscosity increases with the increase of the concentration of solid phase volume. When the solid volume concentration reached 35%, the viscosity increased rapidly, when reached 50%, close to the highest viscosity, heavy suspension showed almost no liquidity, slurry flow state, the suspension through the screen will be very difficult, and the dielectric effect is very poor.
