[email protected]Influencing the size of product.Ball mill that works on the principle of impact is an efficient technique of size reduction through grinding.The size reduction is an important factor for many industrial applications as this process is carried out to increase the surface area, to intimate mixing and to improve dissolution rate, solubility, binding strength and dispersion properties.
