General operation -

Recommended for product research, quality control & technical service applications. Ideal for screening formulations with limited amounts of raw materials. Samples are premixed either by hand or by a high speed disperser then poured into the feed funnel with the Mini mill at low rpm.   With the end plate set to re-circulate the rpm is increased to the desired level and product is allowed to circulate until the degree of product quality is achieved. Product from the feed funnel is pumped into the milling chamber and an agitated bed of grinding beads. These beads can be glass, ceramic or steel and range in size from 0.3mm to 3 mm in diameter. The agitator rotational speed is electronically controlled. Product quality is determined by adjusting the chamber residence time using the metering discharge valve located at the chamber end and by adjusting the agitator rotational tip speed and the product formulation. The chamber and seal housing are water jacketed for efficient cooling. Cooling for the end plate is also available.

Product is removed either by swinging the circulation pipe away from the funnel or by the diverter valve located in the chamber end plate. The mill can also be operated by passing product through the mill in single discrete passes. The through put rate can be adjusted by turning the end valve. Cleaning is achieved by passing a compatible solvent through the feed funnel. With the quick release chamber and end plate dismantling can be achieved in minutes for further cleaning. Mini mills have efficient chamber and end plate cooling.
