Ball mill operate routine

1. Before the ball mills start, check whether erery part of ball mills normal, whether the connecting bolts loose, whether the lubrication of lubrication points is normal, whether the driving device is reliable, whether protective equipment is intact, whether connection of motor carbon is fine.
2. Check whether there is barrier surrounding the ball mills. Forbit persons standing near ball mills when it is starting.
3. Press start button to start the motor and notice the change of electric current. The ball mills' continuous starting don't surpass two times and the first starting and the second starting should separate for more than 5 minutes.If it must be thirdly started, it should be check by electrician and fitter before it is started.
4. The ball mill don't start with other equipment at the same time avoiding the high current.
5. Feed water, feed ore and add steel ball to the ball mill must follow the operate routine. Overload and preoperation are both bad for the ball mill.
6. When the ball mill is running, it should be checked whether the barrel body leak, whether the feeding water or ore is normal, whether the electric current and voltage is normal.If there is some proble, it should be handled quickly.
7. When the ball mill is running, it should be checked whether the bearing or the oil ring is lubricated and whether the temperature of bearing is normal.

Ball Mill

• Ball mill overview

  Ball Mill is crucial equipment for grinding after materials are crushed. It is an efficient tool for grinding various materials into powder. There are two ways of grinding: the dry process and the wet process. It can also be divided into tabular type and flowing type according to different forms of discharging material.

• Ball mill application

    Ball Mills are widely applied in cement industry, chemical industry, new building materials, fire-resistant materials, fertilizer, porcelain and glass industry etc. Two kinds of process methods: wet process and dry process are both available. SBM which is a famous ball mill manufacturer in China has tried our best to service for you.

• Ball mill main features and benefits

  • 1. The hollow axis adopts the cast steel and the lining can be replaced. The big rotary gear is forged from cast rolling gears.
  • 2. The barrel body is inlaid with wearable plates.
  • 3. The ball roller grinding mill machine runs steadily and efficiently.

• Ball mill main parts

  Ball Mill is made up of feeding part, discharging part, gyre part, transmission part (reducer, small transmission gear, motor, and electrical controller) and so on. We also offer spare parts and original wear parts related to the ball mill.

• Operation and maintenance of ball mill

    Ball Mill repair and maintenance are crucial for assuring manufacture efficiency. If not maintained properly, ball mill run-time will be reduced causing substantial economic losses.
  1. The operators must be qualified with the required technical knowledge, received technical training and fully understand the operating principle, regulations of the ball mill.
  2. 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.
  3. 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 and voltage of motor.
  4. To keep surroundings clean where the ball mill run. Every party should be clean unless it's running.

• Ball mill working principle

  This ball mill, a horizontal type and tubular running, has two warehouses. It runs along the outside gear. Materials spirally and evenly enter the first warehouse along the input hollow axis by input devices. In the warehouse, there is a ladder scale board or ripple scale board. Steel balls of different specifications are installed in the scale board. When the barrel body rotates, centrifugal force is produced. At the same time, the steel balls are carried to some 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. In the end, the powder is dischargeed by output material board.
