为解决大型风力干法选煤设备存在的单位面积处理能力低,分选效果不理想,入料外在水分不能大于7%的问题,研制了CFX-48A型差动式风力干选机。应用效果表明:该差动式风力干选机可使设备单位面积的处理能力提高10%～30%,节能50%～65%,可能偏差Ep值为0.17,较原来降低0.06,物料外在水分适应范围由

In order to solve the low unit area treatment capacity, nonideal separation effect and feeding external moisture not over 7% problem existed in the large pneumatic dry separation equipment, a CFX-48A mode differential type pneumatic dry separator was researched and developed.The site application results showed tha t the differential type pneumatic dry separator could make the treatment capacity increased by 10%-30% for the unit area of the equipment, could save the energy by 5 0%-65%，the separation effect Ep value was 0. 17, reduced by 0.06 and could make the external moisture content of the feeding with suitable range from
