For example, the maximum particle size of the ore before crushing is 400mm, and the maximum particle size after crushing is 100mm. The crushing ratio is: i=D/d=400/100=4 (times) Where: i - crushing ratio, times D—the maximum particle size of the ore before crushing, in millimeters; D-the maximum particle size of the ore after crushing, mm; The crushing ratio indicates that the particle size of the ore is reduced by a certain amount of crushing, which is one of the important indexes of the crusher work. 99.9% Nitrogen Generator,99.9% 10Nm3/H Nitrogen Generator,Industrial 99.9% 10Nm3/H Nitrogen Generator,Nitrogen Onsite Generator Jiangsu Minnuo Group Co.,Ltd , https://www.mnuogroupcn.com
The ore is broken every time. The particle size is reduced to a certain extent. The ratio of the maximum particle size of the ore before crushing to the maximum particle size of the ore after crushing is called the crushing ratio.
