GreyStone offers a full line of conveyor systems with lengths ranging from 50 to 200 ft., custom-designed to meet specific application needs. Standard- and heavy-duty portable conveyors, radial stackers and tower radial stackers deliver material flow capacities from 300 to 1,300 TPH with conveyor belt widths from 24 to 54 in. Overland conveyors come in lengths up to 2,500 ft. with belt widths up to 72 in. and deliver a maximum material flow capacity of 3,700 TPH. All conveyor systems have standard CEMA idlers and a lagged-head pulley design with a rubber-coated gripping surface that ensures a tighter hold on conveyor belts to minimize slippage. A self-cleaning, wing-type tail pulley eliminates debris build-up and reduces belt damage.
