Iran is such a country who is rich with mineral resources and the proved mineral materials are more than 60. Besides the world-famous oil and gas resources, it mainly includes gold ore, copper ore, zinc ore, lead ore, chromium ore, iron ore, coal, tin ore, manganese ore, aluminum ore, nickel, magnesium, phosphorus, antimony, tungsten and iron oxide, etc. All these mineral materials are abundant and the metal grade of some is very high. These materials have the very high exploitation value. Iran has very rich copper resources and it has been proven with about 3 billion tons and the average grade is 0.8%. The copper ore accounts for 5% of the world's total reserves, and it is in the third in the world. Iran's coal reserves are about 7.6 billion tons.

For abundant mineral materials, it is very important to have the mining processing production line in Iran. There are lots of miners to choose suitable ore mining production line. Mineral mining production line can be divided into the following steps: excavation, primary crushing, secondary crushing, tertiary crushing, grinding line, beneficiation production line.

The excavation step mainly refers to the raw materials got from mineral mountains. Through exploding, the raw mineral materials will be got from the various kinds of Ore Mountains. Primary crushing usually include jaw crusher to process the mined materials into particles. With jaw crusher, the ore materials will be processed into small size. Jaw crusher is the recognized as the first step crushing machine. Cone crusher or impact crusher will be used in the second crushing production step.

Raymond mill is used for ore preparation and coal preparation such as the fine grinding process of ore raw material, gypsum ore and coal materials.The machine consists of the host, analyzer, plumbing installation, blower, micro powder cyclone separator, while the host consists of rack, diffuser, shovel knife, grinding roll, grinding ring and housing device.

Grinding roller rotates under the centrifugal force. The shovel blade shovels the materials and sends them to a place between the grinding roller and grinding ring, and the materials with grinding pressure will be crushed into powder. Then the powder will be blown up by the blower to theanalyzer. The powders that meet the fineness can go through the analyzer and are collected by the micro powder cyclone separator, otherwise, the powders will be returned to the grinding chamber to be ground again.

Raymond mill is widely used in ultrafine grinding process of barite, calcite, potassium feldspar, limestone, talc, marble, dolomite and gypsum, etc. It also can do the super finegrinding processof non-flammable and non-explosive ore, chemical and construction materials with Mok's hardness under 9.3 and humidity below 6%.
