The mill is designed for grinding grain of wheat, rye and other crops with a moisture content of up to 20% to a given fineness in the preparation of samples to determine the quality of gluten, “falling number” and other quality indicators. The mill can be used in laboratories of grain-receiving, flour-grinding enterprises, in the system of agriculture, breeding and research organizations. The principle of operation of the mill is based on imparting centrifugal acceleration to the processed material, in which it is pressed against a rough (abrasive) surface and crushed to a stable particle size. The resulting meal, having passed the calibration sieve, enters the cyclone, from where it is discharged into the atmosphere through the filter, and the meal is poured into the receiving glass. The mill is equipped with calibration sieves with a hole diameter of 0.8, 0.9 and 1.0 mm
