Research Work Use Of Ball Milling In Manufacturing

A ball mill is a type of grinder used to grind and blend bulk material into qdsnanosize using different sized balls the working principle is simple impact and attrition size reduction take place as the ball drops from near the top of a rotating hollow cylindrical shell the nanostructure size can be varied by varying the number and size of balls the material used for the balls the material used for the surface of the cylinder the rotation speed and the choice of material.
