how ball mill works

introduction:

ball mill

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. 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.

how ball mill works | working principles:

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

ball mill maintenance:

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, receive technical training and fully understand the operating principle, performance an 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,voltage of motor.
4.to keep surroundings clean where the ball mill run. each part of it should be clean unless it’s running.
