Wet Dusting

  1. 2. <ul><li>Slurry is a mixture of rockdust and water </li></ul><ul><li>When mixed, slurry can be compared to a runny mixture of cement. </li></ul><ul><li>This mixture is sprayed onto the roof, ribs and floor through nozzles. </li></ul><ul><li>Spraying can be done manually through a single wand similar to a pressure washer. </li></ul><ul><li>Entry dusting is achieved through a series of nozzles. As the operator trams the entire entry is coated. </li></ul>WHAT IS SLURRY DUSTING
  2. 3. <ul><li>NO AIRBORNE DUST </li></ul><ul><li>DUST IN THE INTAKE WITH MEN INBY </li></ul><ul><li>MORE COVERAGE WITH LESS DUST </li></ul><ul><li>ADHERES TO THE TOP AND RIBS BETTER THAN DRY DUST </li></ul><ul><li>LONGER LASTING, GO LONGER BETWEEN DUSTING </li></ul><ul><li>EASY MIXING AND QUICK CLEANUP </li></ul>ADVANTAGES OF SLURRY DUSTING
  3. 4. <ul><li>One 50# bag of dust requires approximately 2.8 gallons of water </li></ul><ul><li>A 50Lb. bag of dust will make 10 gallon of slurry </li></ul><ul><li>Each gallon of slurry will cover roughly 50 square feet </li></ul>MIXTURE AND COVERAGE
