Mechanical conveyor operates well in harsh conditions
A conveyor that uses a thin film of air to reduce the friction between the belt and the trough reliably conveys crushed rock at a concrete products facility.
A Carder Concrete Products facility located in Bernalillo, N. M., uses crushed rock with 5/8, 3/4, or 1-inch diameters to manufacture concrete septic pipe. A dump truck delivers the crushed rock, dumping it over a metal grating. The rock then falls through the grating into a hopper that feeds a chute leading to a conveyor, which moves the rock into a silo.
