The OK™ Mill was originally designed for cement grinding. In 2017 we released the OK™ vertical roller mill for raw materials grinding. The OK™ Mill's modular design comes with unique flexibility, showcasing parts commonality, where spare parts can be shared between vertical roller mills regardless of size and application.

The vertical roller mill is used to grind the material by using the principle of material bed pulverization. It gathers materials for grinding, conveying, powder selection, drying and separation of metal blocks and medium ore.

The power ingesting of a grinding process is 50-60% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time

Vertical Roller Mill Overview. The vertical roller mill has become the preferred equipment for cement industry raw material grinding, is estimated to have more than 600 sets of production. Large vertical mill capacity has reached 600t/h, the transmission power of 5000KW.

For the past three decades the vertical roller mill has emerged to be the preferred choice for grinding raw materials. With the grinding capacity of a vertical roller mill and the ability to dry, grind and sort in a single unit, the vertical roller mill offers a definite advantage over the ball mill system [10] .

The vertical raw mill in cement industry is equipped with a hydraulic tension device, which mainly controls the relative pressure of grinding roller to the millstone. The crushing pressure can be adjusted according to the hardness of the grinding material. The materials after grinding continue to move towards the edge of the millstone.

The vertical cement mill is especially suitable for large-scale milling of various ores, and grinding of various block, granular and powder materials because of its superior performance. So it is widely used in cement, electric power, metallurgy, glass fiber, coal and other industries. Working principle of vertical cement mill
