Pdf Design And Fabrication Of Mini Ball Mill

may 30, 2016 this project is to design and fabricate a mini ball mill that can grind the solid state of raw materials into fine powder. ball mill is a cylindrical device that used to grind and blend raw ball mills grind material by impact and attrition. the degree of milling in a ball mill is influenced by; residence time of the material in the mill chamber. the size, density, and number of the balls. the nature of the balls feed rate and feed level in the vessel.If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill. the point where the mill becomes a centrifuge is called the critical speed and ball mills usually operate at 65% to 75% of the critical speed.

The Operating Principle Of The Ball Mill

the operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. the material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. then, discharge of ground material performed the overall design of ball mills and rod mills are compact, with simple operation and easy maintenance. but the both are different in performance and applications.
