ZQS周期式高梯度磁选机的优化与应用

介绍了非金属矿提纯专用设备ZQS周期式高梯度磁选机的发展背景、适用范围及设备的分选原理及技术特点，对ZQS周期式高梯度磁选机在使用过程中出现的精矿损失率高、振动板筋板开裂、线圈腔体积水三个问题分析了原因，通过优化上下磁极结构、增强振动板刚度、线圈腔体底板开孔的方式在设备整体成本增加很小的情况下成功解决了设备使用中存在的问题，同时也提高了设备的使用性能。三项优化设计应用于ZQS-1 000高梯度磁选机的设计，样机在广东一石英砂厂进行工业试验，振动筋板无开裂现象，精矿损失率低，线圈腔体无积水现象。在给矿含Fe2O3 0.018 4%，处理量为25.59 t/h的条件下，获得的石英精砂含Fe2O3 0.007 4%，石英精砂质量达到光伏玻璃石英砂原料含铁量要求。

Optimization and Application of ZQS Periodic High Gradient Magnetic Separator

The development background， application scope， and separation principle and technical characteristics of ZQS periodic high gradient magnetic separator，which is special equipment for non-metallic ore purification，was introduced. The reasons for three questions of the high loss rate of concentrate， cracking of the rib plate of the vibration plate， and hydrops in the coil cavity were analyzed.The overall cost of the equipment is increased very little with optimizing the structure of the upper and bottom magnetic poles， enhancing the rigidity of the vibration plate， and making holes in the bottom plate of the coil cavity， which successfully solved the problems in the use of equipment and improved the performance of the equipment at the same time. Three optimized designs were applied to the design of the ZQS-1 000 high gradient magnetic separator and the prototype was tested in a quartz sand factory in Guangdong. Vibration ribs has no cracking， the concentrate loss rate was low， and the coil cavity had no water accumulation. Under the conditions of the feeding containing 0.0184% Fe2O3 and a processing capacity for 25.59 t/h， the quality of quartz sand is of Fe2O3 0.007 4% and meets the raw material iron contents requirements of photovoltaic glass quartz sand.
