Raymond Mill

  • Raymond mill outline

    Raymond mill is applied widely in mining, construction, chemical industry and metallurgy etc. After many years of practice and improvement by manufacturer SBM, the structure of Raymond mill is getting perfect by low consumption, low investment, environment friendly, small occupation area, and more efficient than the traditional industrial grinding mill.

  • Raymond mill details

    raymond millApplication area: mining, construction, chemical industry and metallurgy etc.

    Main components: Raymond mill is collocated with jaw crusher, elevator, electromagnetic vibrating feeder, main unit, classifier, collector, cloth deduster and high-pressure blower and so on.

    Successfully grinded material: quartz, feldspar, barite, fluoride, cinder, cement clinker, dolomite, limestone, gypsum, talcum, calcite, bauxite, granite, slag, gold ore, clay, kaolin, graphite, basalt

    Material requirements: non-flammable and non-explosive stuff which has the Moh’s hardness below 7, humidity less than 6%.

    Components of grinding line: mainframe, classifier, collector, dust cleaner, blower and other optional equipments

  • Raymond mill features

    1. Raymond mill plant is a vertical structure of strong systematic characteristic, so it occupies small area. From crushing of raw material to grinding and packing is an independent production system.
    2. Compared with other milling plants or traditional Raymond mill, its passing ratio achieves 99%, this is what other grinding mill cannot reach.
    3. Our Raymond mill's driving system of main frame adopts airtight gearing and pulley, drives smoothly and operates reliably.
    4. The electric control system of Raymond mill is centralized controlled, so the automatically is high, no people are needed in the operating room when the Raymond mill is working.
    5. Raymond mill is easy to adjust, small in dimension, light in weight, with lower oil and power consumption and easy to maintain.

  • Raymond mill operating principle

    Load the stuff for grinding evenly and continuously into the grinding chamber of the main frame. Due to the centrifugal force in rotation, the roller swings go outward and presses closely upon the ring. The shovel carries the stuff to the space between the roller and ring. When the roller rolls, the stuff is thus grinded.

    After being grinded, the stuff is to be routed to the classifier along wind belt of the blower and the rough powder will be put back to the grinder for regrinding. The fine powder flows into the cyclone collector together with air flow and is expelled from the powder output pipe as product.

    In the grinding chamber, since the stuff contains moisture to some extent, the heat generated during grinding makes the moisture evaporate; since the pipeline joints are not airtight, the external air is sucked in and the circulation air mass increases. In order to enable the grinder to work in negative pressure, the increased air flow is guided to the deduster and sequentially to the atmosphere after purification.
