LM Vertical Roller Mill

SHANGHAI SHIBANG MACHINERY CO., LTD is one high-tech enterprise, which involves R&D, production, sales and service as well. In the past 20 years, we devote to producing mining equipments, sand making machines and industrial grinding mills, offering expressway, rail way and water conservancy projects the solution of making high grade sand and matched equipments.

As The Term Suggests

LM Vertical Roller Mill, which is developed and launched by SBM, sets medium crushing, drying, grinding, classifying and other functions as a whole, being the ideal equipment in the grinding industry. LM Vertical Roller Mill is a type of milling equipment widely used in cement, chemical industry, coal and electricity industries, featured by a small size, low energy consumption, little noise, simple process and compact arrangement, etc.

Product Application

According to customers’ requirements, SBM success in absorbing foreign experience and world-advanced technology, and in producing our vertical products, with self-owned intellectual property right. LM series vertical grinding mill is widely used in grinding non-flammable and non-explosive materials under 9.3(the Moh’s hardness), such as grinding quartz, feldspar, calcite, talcum, barite, fluorite, iron ore, copper ore quartz, slag, cement clinker, zircon sand, fly ash and carborundum, coal, etc.

Product Advantage

  • Production of low-cost, high-performance

    Set of crushing, drying, grinding, grading conveyor in one, simple system, compact layout, covers an area of approximately 50% of the milling system, and open lay out,thus greatly reduce the investment costs. Using grinding roller roller compacted milled material directly in the disc, low energy consumption and milling system energy savings of 30% to 40%.

  • Good stability, high reliability

    Grinding roller is not in direct contact with the disc and roller and liner quality material, so long service life, less wear. Mill roller roller sets can turn it over to extend the service life doubled.

  • Product size composition well

    Hot air mill direct contact with the material, drying ability, as the mill system to save a dryer, saving energy and materials to meet different humidity requirements by adjusting the temperature of hot air. Since the short residence time of the material in the mill, easy to detect and control the product particle size and chemical composition, to reduce duplication of milling, stable product quality.

Operational Principle

When LM Vertical Roller Mill working, motor driven disc reducer rotating material air lock feeder from the feed inlet and on disc central, hot air from the inlet into the mill.With the disc rotation, the material under the effect of centrifugal force, to the disc edge to move through the annular groove on the disc by grinding roller compacted crushed, crushed material in the disc edge, high-speed airflow with air ring since particles straight into the re-grinding on the disc, the flow of material through the upper separator, the role of the rotating rotor, meals from the cone bucket fell on disc re-grinding, qualified powder with a mill with the air by closing devices to collect dust, represents the product, the moisture-containing material in the process of contact with the hot gas stream is dried, by adjusting the hot-air temperature, can meet the requirements of different humidity materials, to achieve the desired product moisture.
