Fine Grinders - Information

Designed to grind dry, free-flowing material down to 200 mesh with very tight particle size distribution. The highly efficient design allows for easy access to all internals and is well suited for heat sensitive materials such as resins, sugar and powder coatings. The larger screen to horsepower ratio allows for more capacity. The outboard bearing design and dual "O" ring seals on the large access door, provide a more dust controlled grinding environment. Quick removal of the reversible rotor is possible with the removal of one bolt and rotor blades are easily replaced without further balancing of the rotor required.
