As for Rod Mills, the image above best expresses what is going on inside. As rocks is feed into the mill, they are crushed (pinched) by the weight of its 3.5” x 16’ rods at one end while the smaller particles migrate towards the discharge end and get slightly abraded (as in a Ball Mill) on
احصل على السعرالحصول على الاقتباسWhatsAppAt low speeds the ball rolled over each other and attrition takes place. 1,2 At critical speed the centrifugal force just occurs as a result the balls are picked up by the mill wall and carried nearly the top where that break contact with the wall and fall to the bottom to be picked up. In this manner impact stress will also be induced and the size reduction made effective.
