Crushing of materials in the spherical mill with the mixer

Abstract

In article results of a grinding such differing on the ability for grinding materials as a chalk, kaolin, amorphous silicon oxide, in a spherical mill with a mixer are presented. In quality milling bodies of 2.8–3.0 mm were used pig-iron a ball in diameter. Speed of working body made 10 m/s. The initial fraction of 0.5–3.0 mm as a result of a grinding is finished till the final size 0.2–50.0 ?m. Approximately 80% of particles had the size less than 10 ?m. Dependences of efficiency dispersion from duration of influence for the different defining sizes of particles are received. Possibility of analytical representation of the total characteristic in the form of the equation of Rozina – Rammlera is shown.
