矿泥通常指矿石中的细泥部分,按其来源分为原生矿泥和次生矿泥。原生矿泥一般指矿床内部由于地质作用或矿床长期经受各种自然风化蚀变作用逐渐形成的一些泥质矿物,次生矿泥则是由于在采掘、装运、破碎、磨矿、搅拌等一系列开采和加工过程中所产生的一些微细泥质矿粒。采用破碎+筛分流程的选矿厂,当入选矿石中含泥量较高时,会造成破碎机通过能力不足及检查筛分效率低下等一系列问题,进而影响整个生产系统的处理能力。为消除矿泥对各项工艺指标的影响,实际生产过程中,通常在中碎之前设置洗矿筛分作业,并通过相应分级设备,将 Mud usually refers to the fine mud in the ore part, according to their sources are divided into primary sludge and secondary sludge. Primary sludge generally refers to some of the argillaceous minerals gradually formed in the deposit due to the geological function or long-term natural weathering and alteration of the deposit. The secondary sludge is due to a series of processes such as mining, shipping, crushing, grinding and mixing Some fine argillaceous minerals produced during mining and processing. When the concentrator with the crushing and screening process is used, when the content of clay in the selected ore is high, it will result in a series of problems such as the insufficient capacity of the crusher and the inefficiency of checking and screening, thereby affecting the processing capacity of the entire production system. In order to eliminate the impact of the sludge on the various process indicators, in the actual production process, usually set in the broken before washing ore screening operation, and through the corresponding grading equipment, will be
