Ball Mill Working Principle

Closed system: The bulk materials are crushed to the desired size by jaw crusher. Then the materials will be sent to the storage hopper by the elevator. After vibrating feeder, materials will be even quantitatively and continuously into the indoor host grinding.After grinding, the powder is away by fan airflow,

the powder selecting machine will grade the powder. Accord with the fineness of fly will be into the large cyclone collector with the gas flow through the pipe to be isolated and collected, and then the powder will be discharged from the powder tube discharge. The airflow returns air duct fan from large cyclone collector inhalation top.

Open system: In the grinding chamber internal grinding material with certain water content, the grinding heat generated in grinding chamber gas vaporizing expansion changes the gas flow rate, and the various machine pipe joint seal is not strict, let the outside gas is inhaled, the circulating air volume increase, therefore to achieve balance through adjustment of air exhaust fan and host the pipe, and the excess gas into the bag filter, the residual gas into the powder collected, the residual gas is discharged after purification.

Basalt processing equipment

On the processing, mining crushing, grinding machines are at demands, such as spiral classifiers,magnetic separation machine,hydraulic cyclone,high frequency screen,impact crusher,jaw crusher,cone crusher,mtw milling machine,mtm trapezium grinder as well as some other machines produced by SBM.

The Production Process Of Basalt Processing

  • The raw material is conveyed to the jaw crusher for primary crushing through the hopper and a vibrating feeder uniform feeding. After primary crushed material and fine material screening by vibrating feeder are transmitted to the transfer material pile by a belt conveyor .

  • The transmission belt machine will convey stockpile material to the cone crusher for finely broken, and then screened by the circular vibrating screen. Larger particles back to the cone crusher to be broken again; medium grained material is sent into sand making machine for fine crushing and reshaped. Grade qualified materials is the final product after washing by sand washing machine.
  • Medium grain material is sent into the sand making machine for crushing, and then screened by a circular vibration sieve. Larger grain size material is returned to the sand making machine to be broken again. Qualified products are sent to the stockpile storage by the belt conveyor, and fine particles are sent into the sand washing machine to clean.
  • Material that is sent into the sand washing machine is as part of the final product to be transferred by the conveyor belt to material pile.
