Superfine vertical mill for large-scale production of non-metallic mineral ultrafine powder
  • Overview
  • Features
  • Working Principle
  • Specifications
LUM Series Ultrafine Vertical Roller Mill is innovative high-end grinding equipment upgraded on the basis of HLM grinder by our engineer who have learnt advanced grinding technology at home and abroad. It is one non-metallic mineral processing for large-scale production of large-scale fine grinding Powder machine.
  • 1.Maintenance convenient

    (1)Roller can be pulled outside the machine by hydraulic device, large space for replacing the roller liner and repairing the mill, maintenance is very convenient. (2) Roller sleeve can be double sides used , extend the wear-resistant material's life.

    2.Environmental protection
    (1) LUM vertical mill whole system vibration is small, low noise;
    (2) The system is whole sealed, full negative pressure operation, no dust spill, basically can realize without dust in the workshop.
  • 3.Balanced Energy Storage Device

    The balanced energy storage device can improve rigidity of equipment.While ensuring that the equipment runs in high efficiency,it can effectively reduce equipment's amplitude,stable and reliable in performance;in fine powder or superfine powder production,it shows more advantages.

    4.Sphere Upper Structural Support

    The unique "sphere upper support structure" changes the roller assembly from cross arm shaft dangling structure to vertical shaft horizontal pendulum structure to realize long-term safe operation.
