Abstract

Изобретение относитс к устройствам дл тонкого измельчени различных материалов повышенной твердости. Цель - повышение качества готового продукта и снижение энергоемкости. Центробежна мельница содержит корпус 1 с двум размольными камерами 2, соединенными между собой тангенциальным каналом 3. Сверху корпус мельницы ограничен плитой с двум загрузочными патрубками 5. В каждой камере имеетс ротор, который состоит из вала, диска 8 и лопаток, выступающих за пределы диска ротора на 1/8-1/10 их длины. На вертикальных стенках тангенциального канала 3 установлены отбойные плиты 10 таким образом, что их отбойные поверхности лежат в одной плоскости и наход тс одна от другой на рассто нии 1/4-1/8 ширины тангенциального канала. На 1/4-1/2 поверхности вертикальных стенок размольных камер 2 до отбойных плит 10 установлены ударно-отражательные отбойники 11. В канале 3 расположен выгрузочный патрубок. 2 ил.The invention relates to devices for the fine grinding of various materials of increased hardness. The goal is to improve the quality of the finished product and reduce energy intensity. The centrifugal mill contains a housing 1 with two grinding chambers 2 interconnected by a tangential channel 3. On top of the mill housing is limited by a plate with two loading nozzles 5. Each chamber has a rotor, which consists of a shaft, a disk 8 and blades protruding beyond the rotor disk at 1 / 8-1 / 10 of their length. On the vertical walls of the tangential channel 3, the fender plates 10 are installed so that their fender surfaces lie in the same plane and are located one at a distance of 1 / 4-1 / 8 of the width of the tangential channel. On 1 / 4-1 / 2 of the surface of the vertical walls of the grinding chambers 2 to the fender plates 10, there are installed impact-reflective chippers 11. A discharge port is located in channel 3. 2 Il.

Claims

Claim

A centrifugal mill containing a housing with two grinding chambers interconnected by a tangential channel, in which baffle plates, rotors with booster blades mounted on a disk, located in each chamber having a loading nozzle, an unloading nozzle equidistant from the axes of rotation of the rotors are located, characterized in that, in order to improve the quality of the finished product and reduce energy intensity, the baffle plates are located on the vertical walls of the tangential channel, while the baffle surfaces lie in the same plane and are located one from another at a distance of 1 / 4-1 / 8 of the width of the tangential channel, and on 1 / 4-1 / 2 of the surface of the vertical walls of the grinding chambers to the baffle plates, shock-reflective chippers are mounted, and the accelerating blades protrude beyond the limits of the rotor disk by 1 / 8-1 / 10 of their length.
