LM series vertical grinding mill is one advanced powder making mill which is developed through many years' research &experience and bringing in the latest mechanical techniques of Europe. It is one complete plant that integrated with drying, milling, classifier and elevator.

Working Principle

Motor drives millstone-device through reducer and the hot air comes into the machine from the air inlet. When the materials are fed to the centre grinding plate, they move to the edge of grinding plate under the action of centrifugal force. Then the material are grinded by the grinding rollers when they pass through the grinding zone. Crushed materials continue to move to the edge of the grinding plate until taken away by the airstream. The big ones fall down and the process of grinding continues. The qualified ones pass through the separator and are gathered by the collector.If there are some irons or some other sundries, they will fall down from the grinding chamber under the action of gravity when they move to the edge of millstone device. Finally, the scraper will clear them from the grinding machine.

It is the high standard mill with many advantages, like taking a little space, high efficiency and energy-saving, and the LM vertical mill fully meets the requirement of clients in the high production of powder. LM Vertical Grinding Mill has wide application in metallurgy, construction, chemical and mining industries, being the preferred equipments in grinding industry. 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.

Grinding Mill Processing Technology

LM vertical grinding system is made of raw material feeding system, grinding system, drying system and final-products transportation system, etc. For special materials, the auxiliary system is optional, such as explosion protection system. The drying system include two types, the pulse dust filter open circle system (without hot air) and pulse dust filter open circle system (with hot air). Raw materials in the hopper are lifted by elevator and pass though air-lock device, enter into the grinding chamber. Ground by the LM grinding mill, powders are collected and transported to silo. The advantages of this system are that it has simple structure, low investment and operation cost. For there is no heat source, it is suit for grinding dry material, the moisture should below 4%.

Grinding Mill Machine Advantages

This product sets crushing, drying, grinding, classifying and transportation as a whole, and it has simple system and compact structure, it takes 50% occupation area of ball mill and can be installed in outdoor sites, reducing the investment cost greatly.

  • Digitalized Processing, Higher Precision

    There are tens of lines of numerical controlling machine tools. Operations such as steel plates’ cutting, bending, planing, milling and paint spraying are all controlled numerically. The machining precision is high, especially for the core parts.

  • Short Grinding Time & Low Iron Content

    The materials linger in the grinding mill for a short time, which can reduce repeated grinding and is easy to detect and control the grain size and chemical component of the product. In addition, the grinding roller and millstone do not contact directly.

  • Less Comprehensive Investment

    LM Vertical Grinding Mill integrates crushing, drying, grinding, separating and transport. The structure is simple while the layout is compact. Its occupational area is about 50% of that of the ball-milling system. The LM grinding mill can also be arranged outdoors, which greatly reduces the investment cost.

  • Greener & More Automated

    The operation of LM grinding mill is stable and has small vibration, so that the noise is small. The system is sealed in an integral manner and works under negative pressure, so that there is no dust spilling and the environment can keep clean with the emission standard far better than the international standard.
