Description
Ball mill application:Ball Mill is a key equipment to grind all kinds of ores and other materials. Which 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. Ball mill are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. Various classifiers, such as screens, spiral classifiers, cyclones and air classifiers are used for classifying the discharge from ball mills. Ball mill is an efficient tool for grinding many materials into fine powder. The ball mill is used to grind many kinds of mine and other materials, or to select the mine. It is widely used in building material, chemical industry, etc.
Ball mill organization character:By feeding department, the exiting material department, the rotor, the transmission department (speed reducer, small transmission gear, electrical machinery, electric control) and so on main part composes. The midlevel axis uses the steel casting, the inside lining is detachable, rotates the big wheel to use the casting to roll the tooth processing, tube in vivo besets with by the wear-resisting backing, has the good resistance to wear. It revolves steadily, operation reliable.
Note: According to material and emissions mine type, may choose the dry ball mill and the wet check ball mill.
Working principle of ball mill:The ball mill is a horizontal rotating device transmitted by the outer gear. The materials are transferred to the grinding chamber through the quill shaft uniformly. There are ladder liner and ripple liner and different specifications of steel balls in the chamber. The centrifugal force caused by rotation of barrel brings the steel balls to a certain height and impact and grind the materials. The ground materials are discharged through the discharging board thus the grinding process is finished.
