平皮带光选机是一种粗粒矿石预选脱废的新设备,它利用合格矿石与废石表面对光线漫反射率的差别进行拣选。入选矿石在平皮带上呈单层矿粒流被光检系统检测,产生的信号经电子控制系统处理后,激励相应的高速喷气阀动作,把合格矿石从矿流中分离开来。该机的主要特点是设备结构较为简单,而获得的分选指标较好,单机处理量较大。在工业试验中,脉石选出率平均84.4%,废石丢弃率平均83.8%,分选20～30mm 和30～50mm 粒级的矿石,每小时处理量分别达到4.5和7T。
Flat Belt Light Sorter is a new equipment for the preselection and removal of coarse-grained ores, which uses the difference of diffuse reflectance of light between qualified ores and waste rock surfaces. The selected ore on the flat belt was a single layer of mineral particles flow detected by the optical detection system, the signal generated by the electronic control system processing, the corresponding high-speed jet valve actuation action, the separation of qualified ore from the stream. The main features of the machine is the structure of the device is relatively simple, and access to the sorting index is better, stand-alone handling capacity. In industrial tests, the gangue selection rate averaged 84.4% and the average abandonment rate of waste rock was 83.8%. The ore size of 20 ~ 30mm and 30 ~ 50mm was sorted out. The hourly throughput reached 4.5 and 7T respectively.
