Ball Mill Machine for Limestone Gypsum
Introduction of Ball Mill Machine
Small Ball Mill is used to grind many kinds of mine and other materials, or to select the mine. The Dry Ball Mill is an efficient tool for grinding many materials into fine powder, such as cement, silicate, gypsum and limestone. Industrial Ball Mill is widely used in building material and chemical industry. There are two ways of grinding: the dry way and the wet way. Ball mill can be divided into tabular type and flowing type according to differentexpelling mine. Ultimate particle size depends entirely on how hard the materials you're grinding is, and the time how long the ball mill runs.
Working Principle of Ball Mill Machine
Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation. If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill. The point where the mill becomes a centrifuge is called the "Critical Speed", and ball mills usually operate at 65% to 75% of the critical speed.
