Iron oxide red is not only iron oxide, but also known as limonite, burnt ochre, iron red, red powder, etc., which is the main component of iron rust. Iron oxide is often called iron oxide red in industry, which is reddish brown powder and easy to dissolve in strong acid and medium strong acid. At present, iron oxide red is commonly used in paint, ink, rubber and other industries. It can be used as ironmaking raw materials, as well as catalysts, polishing agents for glass, gemstones and metals.

Iron oxide red grinding powder process, generally divided into iron oxide red coarse powder processing ( 0-3MM ), fine powder processing ( 20 mesh-400 mesh ), and iron oxide red ultra-fine powder deep processing ( 400 mesh-3250 mesh ) three types.

First stage crushing : iron oxide red bulk material by crusher broken into the feeding fineness of mill ( 15mm-50mm ).
The second stage of grinding : broken iron oxide red small pieces of material sent to the hopper by hoist, and then by the vibration feeder uniform quantitative into the grinding mill grinding chamber for grinding.
Fine powder processing generally use LM vertical roller mill, MTW European mill, 5X European intelligent mill ; ultra-fine powder processing is generally selected LUM ultrafine vertical mill, MW ring roller mill, coarse powder processing CM European coarse grinding, straight-through centrifugal mill.
The third stage classification : after grinding materials are classified by the separator, unqualified powder is classified by the separator and returned to the host machine to regrinding.
The fourth stage of powder collection : the powder in accordance with the fineness is separated and collected in the dust collector through the pipeline with the air flow, and the collected finished powder is sent to the finished product silo through the discharge port by the conveying device, and then uniformly packaged by the powder filling tank car or automatic packer.
