Aiming at the dehydration process of fine coal with the slime centrifuge, influences of feedings size, feedings concentration, centrifugal factor and residence duration on the dehydration effect are studied. The re sults show that variation of the feedings characters have great influences on the dehydration performance of the slime centrifuge, so when they change, the centrifuge's working parameters need to adjust so as to ensure the dehydration performance. The centrifugal factor and the residence duration of the efficient slime centrifuge can be adjusted precisely as the feedings characters change, thus it has good adaptability for feedings with different characters, and is has more advantages than the traditional slime centrifuge.%针对煤泥离心脱水机对细粒煤的脱水过程,研究了入料粒度、入料浓度、离心因数与停留时间对脱水效果的影响.结果表明,入料性质的变化对煤泥离心脱水机脱水效果的影响较为显著,入料性质变化时应及时调整离心机参数才能确保脱水效果.煤泥高效离心机的离心因数、物料停留时间可根据物料性质的改变进行精确调节,对不同性质的入料均有较好的适应性,相比较传统煤泥离心机有较大的优势.
