Polished Ball Mill, For Crushing Machine, Feature : Compact Designs, High Strength, Optimum Quality

ball mills are one of the most precise, reliable and cost effective methods of fine grinding solids in either a wet or dry state. ball mills are referred to by many names including pebble mills, tube mills and attrition mills, but no matter what the nomenclature they all operate on the same efficient principle. a horizontal cylinder is rotated at a predetermined speed that sets the balls into a tumbling and cascading motion which impact the solids in a very predictable and controllable fashion. because the process takes several hours, the particles will not only be finely milled, but will exhibit a narrow particle size distribution. tumble milling is efficient and puts more energy into milling and less into wasted friction which both reduces contamination and eliminates temperatures spikes. for very heat-sensitive products, a cooling jackets can be provided for temperature control. scale-up of tumble mills benefits greatly from the fact that they become more efficient with increasing size. tumble mills are designed for each application, taking into consideration all of the solids characteristics and whether the solids will be discharged wet or dry.
