VXPmill for fine & ultra fine grinding | FL

There is a large gap between the tip speed and power intensity of the low-speed vertical mills and the high-speed horizontal mills. The VXP mill bridges the gap between high-speed and low-speed mills. The VXPmills are designed for fine and ultra fine grinding applications. In practice, the mill performs best when the feed has a normal distribution.

Particle Size and Standard Deviation - CPM

Rolls may operate at differential speeds depending on the task the mill is called to perform. Cracking, crimping and flaking use lower roll (peripheral) speeds - 1,000 Ft/min (5 M/sec) up to 2,200 Ft/min (11 M/sec) and no roll speed differentials. Mills used to grind will operate with higher roll speeds - 1,500 Ft/min (7.5 M/sec) up to 3,000 Ft/min
