    A Ball Mill is a rotating drum with dozens of lead balls inside. The 3 chemicals are loaded into the Ball Mill, along with the lead balls, sealed shut and allowed to rotate for anywhere between 1 hour and 24 hours. As the Ball Mill rotates, the lead balls will crush the chemicals together, forcing some of the Potassium Nitrate into the pores of ...

  • 5 Best Practices for Raw Material Procurement

    1) Calculate and share detailed raw material demand forecasts at regular intervals with service centers and mills . By sharing what we call a "material demand profile" with the sources of the raw material, OEMs can reduce risk for their raw material suppliers enabling them to operate more responsively, while increasing the OEMs ability to control pricing and ensure availability.
