摘　　要：陈四楼选煤厂原先使用的矿浆准备器老旧损坏,导致浮选系统出现问题。针对这一情况,用FCA-3200型雾化跌落式煤浆预处理器代替原来的XK-1600矿浆准备器,分析研究了该预处理器的结构和工作原理,总结了替换后的使用效果。实践表明,FCA-3200型雾化跌落式煤浆预处理器在陈四楼选煤厂实际应用后,改善入浮煤浆的预处理效果,降低了浮选药剂用量,提高了浮选精煤回收率,同时也降低了加压过滤机的排料周期,提高了设备使用效率,释放了浮选系统的产能。The original pulp preparation used in the Chensilou Coal Preparation Plant was old and damaged, causing problems in the flotation system. In response to this situation, the FCA-3200 atomized drop coal slurry preprocessor was used to replace the original XK-1600 slurry preparer. The structure and working principle of the preprocessor were analyzed and the effect of the replacement was summarized. Practice shows that the FCA-3200 atomized drop coal slurry pretreatment device improves the pretreatment effect of the suspended coal slurry after the actual application of the Chensilou coal preparation plant, reduces the flotation agent dosage, and improves the flotation clean coal. The recovery rate also reduces the discharge cycle of the pressure filter, increases the efficiency of the equipment, and releases the capacity of the flotation system.
