The Rod grinder is a key machine to grind the crushed materials, and Rod grinder is widely used in powder-making production line including cement, silicate, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc, and the Rod grinder can grind various ores and other materials with dry type and wet type. So the rod grinders can be divided into limestone rod mill, mineral rod mill, ore rod mill and rotary rod mill.Rod mill is loaded by the cylinder body of grinding medium is named for the steel bar and rod mill is generally adopts wet the overflow type, can be used as a first class open circuit grinding, rod mill is widely used in metal and nonmetal mines and water conservancy, building materials department all kinds of ores and rocks.The working principle of Rod mill by the motor through reducer and around big gear reduction drive, or directly by the low speed synchronous motor by rod mill around big gear reduction drive, drive cylinder rotary.Cylinder body is equipped with the appropriate grinding medium and steel bar.Grinding medium under the action of centrifugal force and friction force, was promoted to a certain height, the fall down or discharge state drops.By grinding materials of feeding mouth straight into the barrel inside, by the movement of grinding medium crushing, and the product through the power of the overflow and continuous feed discharge outside, to the next section process operation.Features of rod grinderIt can grind all kinds of hard ore and gravelIt grinds materials in many different sizes as request.Wet or dry grinding method for choosing; High quality steel; It"s a kind of effective and energy saving sand making machine which can save more energy (50%) than traditional sand making machines.Contact Email: [email protected] Number:+86-371-67833161Website: www.chinaquarry.comore separating line: http://www.china-sandmaker.com/product/pp36.html
