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.

Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800’s. The basic construction of a ball mill is a cylindrical container with journals at its axis. The cylinder is filled with grinding media (ceramic or metallic balls or rods), the product to be ground is added and the cylinder is put into rotation via an external

Ball Mill Pdf Size For Gold
In the ball mill, the size and proportion of steel balls have a great influence on the productivity and working efficiency of the mill. For coarse and hard materials, larger steel balls should be selected, for fine and brittle materials, with smaller diameter steel balls, the impact times of steel balls in the mill increase with the decrease of ball diameter, and the grinding between balls

Such mills are common in South African operations; mills are sometimes referred to as tube mills or ROM ball mills and are also operated both autogenously and semi-autogenously. Many of these mills operate at higher mill speeds (nominally 90% of critical speed) and often use “grid” liners to form an autogenous liner surface. These mills typically grind ROM ore in a single stage. A large
