WhatsApp: +86 182036953771. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.
WhatsApp: +86 18203695377The length of the mill is approximately equal to its diameter. Principle of Ball Mill : Ball Mill Diagram. • The balls occupy about 30 to 50 percent of the volume of the mill. The diameter of ball used is/lies in between 12 mm and 125 mm. The optimum diameter is approximately proportional to the square root of the size of the feed.
WhatsApp: +86 18203695377A mill is a machine that is used to break down solid materials into smaller pieces by cutting, grinding, or crushing. The process of milling includes the use of force that acts on a material to tear it apart and reduce its size. Milling improves the performance of ingredients, and the products made from them.
WhatsApp: +86 18203695377The weight of balls is kept constant and size of balls depends upon the size of feed and mill. Working: speed of ball mill. The material to be reduced in size is entered into the machine through a hopper. The electrical supply to the machine is started after a careful closure of the machine feed. The mill is rotated at optimum speed.
