How it works

The OK™ raw mill combines the drying, grinding, material conveying and separation processes into just one unit, which simplifies the plant layout. Its low noise level makes outdoor installation feasible – substantially reducing civil construction costs and improving the working environment.

Key Benefits

• Energy-efficient
  The OK cement mill uses five to ten percent less energy than other vertical roller mills and 30-50% less energy  than ball mill systems. The OK raw mill is based on the same proven technology
• High run factor
  Operating time availability is typically 90 to 95 percent for the OK cement mill. The OK raw mill is based on the same proven technology
• High capacity
  The mill is offered in a full size range including the largest VRM sizes available
• Operating flexibility
  The OK mill achieves 60 to 70 percent of nominal output with half the number of rollers in operation
• Easy maintenance
  Wear liners can be replaced or rewelded inside the mill or the roller swing-out feature can be used for maintenance work externally from the mill

Design Advantages

• The modular design allows for parts commonality with OK cement mill, resulting in reduced spare parts inventory and consistent maintenance practices
• The patented grinding profile and integral separator ensure the mill’s energy-efficiency, stability and reliability 
• Concrete mill stands have faster installation time and reduced cost of installation
• Operation with half of the rollers out of service, allows for continued operation at 60-70 percent of nominal output
• Simple layout and fewer machines in the mill circuit ensure high run-factor and low maintenance costs
• Optimal wear protection on all internal surfaces extends lifetime 
• Segmented roller wear parts made of the hardest possible material without the risk of cracking; very suitable for hard-facing
