Structure And Application Of Grinding Mill

The grinding mill is principally made up of host machine, analysis machine, blower, finished cyclone separator, plumbing device, motor along with other components. And also the host machine includes the rack, air inlet volute, perching knife, grinder curler, grinding ring, cover piece and motor. The auxiliary equipment of MTM Trapezium Grinder includes the jaw crusher, bucket elevator, electromagnetic vibrating feeder, cabinet, etc. Therefore, customers can flexibly choose auxiliary tools based on the site condition.

The grinding mill has got the options that come with stereo system structure, small footprint, flexible configuration and independent production system. The fineness of their final items is uniform using the screening rate (greater than 99%), that is hard for other milling tools to attain. Its driving device switches into closed gear box and belt lever. Besides, all of the important areas of it are constructed with high-quality steel, and all sorts of put on-resistant parts are constructed with high-performance put on-resistance materials. Therefore the MTM Trapezium Grinder has got the options that come with high put on resistance and reliable operation. In addition, its electrical system switches into the centralized controlling method, therefore the milling workshop can realize unmanned operation, and also the maintenance is much more convenient.

  • Low cost, high performance

    Set crushing, drying, grinding, grading conveying into a whole, simple, compact layout, covers an area of approximately 50% milling system, but also can open layout, so the cost is greatly reduced.The grinding roller to direct rolling ground material in the disc, low energy consumption, and ball milling system compared to save energy 30% ~ 40%.

  • Good stability, high reliability

    The hydraulic pressure boost method increases the grinding force, thus effectively improve the yield and milling efficiency. At the same time, limiting device to ensure its only on material grinding, grinding roller grinding ring to prevent outside contact caused by equipment vibration or even wear.

  • Ideal product size

    Because the hot air in direct contact with the material in grinding, drying ability is strong, can mill system saves a drying machine, saving energy, by adjusting the temperature of hot air, can satisfy the different humidity material requirements.


Working Principle

The motor drives the grinding disc to rotate by the reducer, etc. the air lock feeder from the feed inlet fall at the center of the grinding disk, and hot air into the air from entering the mill. As the disc rotates, the material in the role of centrifugal force, move to the edge of the grinding disc, the disc of the annular groove by roller compaction and crushed, crushed material by wind ring high-speed airflow with in the edge of the grinding disc, large particles directly onto the disc re grinding, material gas flow through the upper separator, in under the action of rotating rotor, coarse powder from cone to disc re grinding, qualified fine powder along with air flow through the mill, dust collection device, namely product, moisture containing material is dried in the contact with hot air flow, by adjusting the temperature of hot air, can satisfy the different humidity material requirements, to achieve the required product moisture. By adjusting the separator, can achieve the desired products with different thickness.
