介绍了针对国内目前仍在使用且近期无法淘汰的 XJM— 4型和 FXM— 8型低效高耗浮选机开发的改造实用技术。该技术投资低 ,改造工作量较小 ,可有效缓解选煤厂因浮选能力不足而造成的分选指标落后和生产被动的局面。
This paper introduces the practical technologies for the development of XJM-4 and FXM-8 low-efficient and high-flotation machines that are still in use and can not be eliminated recently. The low investment in technology and the low workload of reconstruction can effectively alleviate the backwardness of the sorting index and the passive production status of the coal preparation plant due to the lack of flotation capacity.
