一、绪言国内现有的连续浮选试验设备,规模最小的为日处理矿石1～2吨。进行一次试验必须花费大量人力和时间来准备试样。若能进一步缩小设备规模,对减少试料准备工作量,节省人力、物力,缩短试验周期,广泛运用连续试验以获得较为可靠的试验结果,更及时地指导现场生产将具有一定意义。为此,我们自行设计制作了一套小型浮选连续试验设备,并初步解决了设备小型化中,中间产品的输送、磨矿分级作业的配套、适用于连续作业的小型浮选机、浮选药剂的简易而准确的添加、矿浆搅拌等问题。进行了单机效率考查及全流程设备运转试验,取得了一定的试验数据。二、试验设备的特点(一)处理能力本套设备的处理能力 First, the introduction of the existing domestic continuous flotation test equipment, the smallest for the daily processing of ore 1 to 2 tons. A test must take a lot of manpower and time to prepare the sample. If we can further reduce the size of the equipment, to reduce the sample preparation workload, save manpower and material resources, shorten the test cycle, extensive use of continuous testing to get more reliable test results, more timely guidance on-site production will be of some significance. To this end, we have designed and manufactured a set of small flotation continuous testing equipment, and initially solved the equipment miniaturization, the intermediate product delivery, grinding and grading operations supporting small flotation machine for continuous operation, flotation Simple and accurate addition of pesticides, slurry mixing and other issues. Conducted a single machine efficiency test and the whole process of equipment operation test, and achieved some experimental data. Second, the characteristics of test equipment (A) handling capacity of this set of equipment handling capacity
