摘　　要：通过增加中碎前预先筛分,对三十亩地选矿厂碎矿工艺流程进行了有效的技术改造。改造后,碎矿粒度明显降低,取得了显著的经济效益。By adding prescreening before secondary crusher, the technical transformation of crushing technology was done in Sanshimudi concentrator. After reformation, ore-crushing size reduces obviously, and Remarkable economic results have been achieved.
