Description of ball mill

SBM Ball mill grinder is the key grinder machine for grinding after the crushing process, and ball milling machine is a efficient grinder mill for grinding many materials into fine powder. Ball milling machine can be used for grinding various ore and other grinder-able materials dry or wet by use dry ball mill and wet ball mill. According to different forms of discharging materials, The ball mill series are divided into grate type and overflow type, and SBM ball mill belongs to grate type.

SBM ball mill is widely used as cement ball mill,limestone ball mill,coal ball mill,granite ball mill,iron ore ball mill etc. The ball mill capacity is from 4TPH( small capacity ball mill) to 20TPH (high capacity ball mill).

SBM ball milling machine 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.
SBM ball milling machine is used to grind many kinds of mine and other materials, or to select the mine. And SBM ball milling machine is widely used in building material, chemical industry, building materials and chemical industry and so on.

• SBM ball milling machine mainly consist of feeding part, discharging part, gyre part, transmission part, (decelerator, small transmission gear, generator, electrical control) and so on.
• The hollow axis of SBM ball mill adopts the cast steel and the lining plate can replace , the rotating big gear processes in the way of casting rolling gear.
• The barrel body of ball mill is wearable well and bears wearable scale board.
• SBM ball mill has the features of stable running and reliable working.

• The operators must be qualified with the required technical knowledge, receive technical training and fully understand the operating principle, performance and regulations of the ball mills.
• The operators should follow the operate principle and lubricate the requirement parts marked in lubrication picture. Untreated waste oil may not be used and keep lubrication points clean.
• Pay attention to check the temperature of bearing not to exceed 60° and make sure every bolt not loose, no abnormal sound, uniform mining feed, steady water feed, normal current, voltage of motor
• To keep surroundings clean where the ball mills run. Every party should be clean unless it's running.

SBM ball mill is horizontal rotating devices transmitted by the outer gear. The ball mill has two warehouses. The materials are transported by feeder to the grinding chamber through the quill shaft spirally, then enter the first warehouse. In the warehouse, there is a ladder scale board or ripple scale board. Steel balls of different specifications are installed in the scale board. The centrifugal force caused by rotation of barrel brings the steel balls to a certain height and then fall to grind and strike the material. After being grinded coarsely in the first warehouse, the material then enters into the second warehouse for regrinding. The above action repeats constantly till the size of materials reaches the required fineness. In the end, the powder is discharges by output material board and the end products are completed.
