Title: Method for facilitating transportation of particulate on a conveyor belt in a cold environment

Abstract: Coal and other particulate can be transported on a conveyor belt exposed to winter weather conditions with reduced slippage of the particulate on the belt surface by periodically treating the belt surface with from about 0.001 to about 0.005 gallons per square foot of belt surface (0.04-0.2 liters/sq. meter) of a composition consisting substantially of water soluble components comprising (A) a water soluble polyhydroxy compound or monoalkyl ether thereof, and (B) a water soluble organic nonvolatile compound having at least one hydrophilic group, (A) being different from (B). The treating composition may also include a small amount of a polydimethyl siloxane if desired.
