【Abstract】 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.更多还原
