主要是对矿粉进行三级磁选处理，再经湿料磁选，磁选所选用的磁场强度为400～1200GS，磁力滚筒转速为60～320转/分，湿料经脱水制得成品铁精矿粉，一般铁含量在35%的矿石，经此法磁选后铁精矿粉铁含量可达68～70%，该联合工艺方法，矿石利用率可达90%，工艺过程中用水量少，节省水，降低成本，减少污染，磁选中的粉尘由除尘装置捕集，不会造成空气污染，本方法是一种生产效率高，产品质量好，无环境污染的具有创造性的工艺方法。

褐铁矿这是含有氢氧化铁的矿石给料机。它是针铁矿HFeO2和鳞铁矿FeO(OH)两种不同结构矿石的统称，呈现土黄或棕色，含有Fe约62%，O27%，H2O11%，比重约为3.6～4.0水泥厂设备。

Selected is mainly on the mineral of magnetic treatment, and the wet material magnetic separation, magnetic separation of magnetic field intensity is 400 ~ 1200gs, magnetic drum speed is 60 ~ 320 RPM / min, wet material after dehydration of finished iron concentrate powder, iron content in 35% of the ore, by this method after magnetic separation of iron concentrate powder of iron content of up to 68 ~ 70%, the combined process method, ore utilization rate of up to 90%, and the process with less water, save water, reduce costs, reduce pollution, magnetic separation of dust from dust catcher, will not cause air pollution. This method is a kind of production efficiency is high, the product quality is good, no environmental pollution of the creative process.
This is the iron ore containing limonite feeder. It is referred to as goethite hfeo2 and scale iron FeO (OH) two different structure of ore, yellowish brown or brown, containing approximately 62% of the Fe, O27%, H2O11%, accounted for about 3.6 ~ 4.0 cement plant equipment.
Dry permanent magnetic roller type strong magnetic high gradient magnetic separator, limonite ore dressing equipment and hematite ore dressing equipment, equipment for limonite ore, hematite ore pressure ball machine. The series of mineral processing equipment for low grade weak magnetic limonite, hematite sorting, can raise the grade 3-7% in one, well solve the has always been low grade limonite, hematite, not into the smelting furnace, sales difficult problem, found a way out of low grade ore, on the economic benefits of hammer type play sand machine. The equipment investment return is high, is a good project to invest less effective quick break machine. Limonite ore dressing equipment, a full set of equipment, the main products are: jaw crushing machine, hammer crusher, roller crusher, counterattack type crusher, vertical crusher, cone bearing energy-efficient ball mill, vibrating screen, automatic anti sand spiral sub machine, high efficiency flotation machine, mine stirred tank, feeding machine, concentrator, mine hoist, mine conveyor, pre adding water into the ball disc, spiral chute, dressing table, washing machines and other equipment hammer type play sand machine.
