Equipment Types and Manufacturers
There are many types of rock dusters provided by manufacturers today. The most common types of dusters are referred to as:
- High pressure bulk - transfers large dust quantities in short time with limited labor required.
- Bantam - portable unit that can mount on equipment to easily dust face areas or can be used to spot dust.
- Slinger - portable duster with good perimeter coating in a single pass.
- Trickle - good for dusting return entries or belt entries, run continuously.
- Wet / Slurry - more coverage per pound of dust, good adherence to coal, can dust with miners inby and easily applied in high areas.
- Mine-wide automated dusting systems - System can be PLC controlled (programmable logic controlled) requiring less manpower.
To ensure mine operators are familiar with these types of rock dusting systems and availability, MSHA has created a link (see below) to rock dusting equipment manufacturers so information on these systems may be disseminated.
