Trapezium Grinder Working Principle

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.

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.

Kaolin processing equipment

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

The Production Process Of Kaolin Processing

  • the first step is dressing; the ore is crushed, ground into 325 mesh powder.
  • the powder is sent into the pulp barrels and water is added, beating stirring the powder, ultrafine crushing to 4500-6000 mesh;
  • after ultra-fine grinding slurry drying is calcined into scattered, calcining furnace, improver calcined when added to 1-3% of the total weight and improver is composed of coal, sodium sulfate and sodium chloride, according to the weight of 10 ∶ 0.3 ∶ 0.2 hybrid. The calcination temperature of 970-990 ℃.
  • to packing to the finished products.
