Features

  • 1. LM sequence vertical roller mill (vertical mill) established of crushing, drying, grinding, separator, conveying in a single, which has a tiny footprint, the process is simple, higher grinding effectiveness, minimal strength usage, reduced noise, bake dry ability, merchandise fineness easy to modify, quick no dust air pollution and maintenance, responsible procedure. Particularly in large-scale grinding process, to totally meet shopper demand, the key specialized and economic indicators have reached the intercontinental sophisticated degree.
  • 2. Grinding wear a small, substantial utilization. Since the vertical mill procedure no direct contact among the metal, and so the grinding wear compact, unit solution attrition is generally five to ten g / t, a little metal contamination from the products.
  • 3. Grinding roll sets can be used the other way up, assistance increase the lifetime and lower creation expenses.
  • 4. outfitted that has a scarce lubrication station, roller bearings lubricated with slim oil centralized circulation, preserve the bearings in reduced and dealing disorders thoroughly clean oily disorders, lengthen the existence of your unit for ongoing and trustworthy operation in the system is operating.
  • 5. Outfitted using an automated control product, which allows remote management, simple to work.
