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.
