摘要
通过螺旋分选机螺距试验，槽底面形状试验，旋转方向及槽的横截面形状试验、确定了适合处理煤矿的螺旋分选机结构参数，实验室及工业试验表明，新型螺旋分选机处理煤矿，具有较好的降灰脱硫作用．
The structure parameters of the spiral concentrator processing coal ore were determined bythe tests in which the pitch. the shape of the sluices,the rotating orientation and were the section shape ofthe spiral concentrator were regarded as changeable parameters.The results of laboratory test s and commercial tests show that the spiral concentrator desinged according to the suitable structure parameters candecrease the content of ash and sulnhur in coial.
