Mikro® V-UMP Mill

The Mikro® V-UMP Mill is a vertical, high-speed cutting mill designed for the fine size reduction of plastics, polymers and fibrous materials that do not respond well to other forms of impact milling. This unique mill design allows for interchangeable rotor configurations depending on the fineness required and was developed to grind heat sensitive and soft materials without liquid nitrogen or conditioned air.

The V-UMP is the next step in the evolution of the Mikro® UMP Attrition Mill by providing the same grind as a rigid rotor setup while adding the flexibility of converting to a pin mill for fine size reduction.

Raw material enters the grinding zone from a feeding device through the centrally located feed inlet. Size reduction takes place between the adjustable stator plate and high-speed rotating grinding plate. The particle size is reduced as the raw feed passes through the tapered plates, which have a wider gap at the center of the plates where the material is introduced, and the tightest gap is at the periphery of the plate where material exits. The finely ground product exits the grinding zone and discharges into the evacuation and collection system. Essentially the fineness of the product is dictated by the number of teeth on the plates, rotational speed of the rotor, as well as the gap between the plates.

Multiple system options are available to further enhance the performance and flexibility of the Mikro® V-UMP Mill.
