WhatsApp: +86 18838072829Sepriadi Sepriadi. Grinding/crushing is a process of reducing the size in a crushing plant to get the desired size. The coal ball mill technique is where the ball collides with the feed on the tube wall, thus cracks will form in the feed which will result in a smaller size. Limitation of the problem in this study is the effect of speed on time ...
