Nov 26, 2019 The ball mill adopts a discharge screen similar to the ball mill, and the function of blocking the internal medium of the overflow ball mill is accomplished inside the rotary part of the ball mill. The discharge screen is only responsible for forcing out a small amount of the medium that overflows into the discharge screen through the internal.View More
This project is to design and fabricate the mini ball mill that can grind the solid state of various type of materials into nano powder. The cylindrical jar is used as a mill that would rotate the material that about to be ground, a motor is used to power the system so that the jar can rotate in high speed and using the regulator controls the speed of the rotation of the jar.View More
The ball impact energy on grain is proportional to the ball diameter to the third power 3 E K 1 d b. (3) The coefficient of proportionality K 1 directly depends on the mill diameter, ball mill loading, milling rate and the type of grinding (wet dry). None of the characteristics of the material being ground have any influence on K 1.View More
