Ball Mill Outline

Ball mill also called ball grinder or ball grinding 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 be divided into tabular type and flowing type according to different forms of discharging material.

Ball Mill Application

Ball mill can grind quartz, feldspar, barite, fluoride, cinder, cement clinker, dolomite, limestone, gypsum, talcum, calcite, bauxite, granite, slag, gold ore, clay, kaolin, graphite, basalt and so on. Ball mill grinding material requirements are non-flammable, non-explosive minerals with Moh’s hardness<9.3, humidity<6%.

Ball Mill Features

1. The hollow axis adopts the cast steel and the lining can replace, the rotating big gear processes in the way of casting rolling gear.
2. The barrel body is wearable well and bears wearable scale-board.
3. This machine run steadily and works reliably.

Ball Mill Working Principle

Ball mill is horizontal type and tubular running device, has two warehouses. This machine is grid type and its outside runs along gear. The material enters spirally and evenly the first warehouse of the milling machine along the input material hollow axis by input material device.

In this warehouse, there is a ladder scale board or ripple scale board, and different specification steel balls are installed on the scale board, when the barrel body rotates and then produces centrifugal force, at this time , the steel ball is carried to some height and falls to make the material grinding and striking. After grinded coarsely in the first warehouse, the material then enters into the second warehouse for regrinding with the steel ball and scale board.
In the end, the powder is discharged by output material board and the end products are completed.

Ball Mill Operate Routine

1. Before the ball mills start, check whether every 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. Forbid 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 doesn’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 doesn’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 preparation 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 problem, 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.
