Ball mill longitudinal sampling 8000m mixermill spex sampleprep jun 22 2004 the ball mill has a cylindrical outer chamber having flanges at opposed ends and has longitudinal lifters attached to the internal surface of the sleeve a sag mill of this small size requires a more
Ball mills consist of a hollow cylinder mounted such that it can be rotated on its horizontal longitudinal axis commonly stainless steel ball is used as grinding media in the ball milling method stainless steel ball is chosen because it low contamination of the material being processed and contains high
Does not represent the performance of any individual ball mill circuit thus the rougher head stream samples cannot be used in a ball mill control strategy for realtime particle size control the online sampling system and ultrasonic particle size monitors were installed on each hydrocyclone battery in
In older mills wear on the mill outlet seals can lead to a progressive and often unnoticed increase in false air with a consequential reduction of actual ventilation through the mill therefore it is good practice to do this blaine test on a monthly basis and ensure that there is a good mill filter exit sampling
