Stone Duster
Clarks Mining Services manufactures an air conveying style hopper duster, which is available with an optional air powered vibrator where damp or humid conditions exist. The stone duster is used by mining companies to spread crushed limestone dust over all exposed surfaces where coal dust accumulates. This ensures that the resultant mixture is incapable of ignition in the event of fires or explosions. Additionally an extension bin is available where larger amounts are required to be spread over a long duration. Various combinations of inlet and discharge fittings are available.
