AUMUND supplies solutions to US gypsum market

Over the past 18 months, AUMUND Corporation has won orders for a variety of specialised conveying solutions at three of the production sites of National Gypsum. The series began with four identical CENTREX® silo discharge machines for FGD gypsum supplied to the Baltimore works in 2016. The order for two Samson® Material Feeders 1600 Series at Shippingport, Pennsylvania followed in early 2017, and most recently, no less than four Samson® Feeders and an AUMUND Apron Feeder type BPB were ordered for National Gypsum’s Apollo Beach plant in Florida, as part of a sophisticated new reception line for natural gypsum.

The four AUMUND CENTREX® CTX-AFD machines were supplied as drop-in replacements for their predecessors that had been in operation in Baltimore, MD, for about 20 years, since being supplied by LOUISE Fördertechnik, Germany, before the company was acquired by AUMUND. The discharge rate of these units is 45 tph each, and many of the spare parts in the customer’s warehouse can be re-used for the new machines.

One of the company’s newest plants, Shippingport, PA, needed a truck reception system for natural gypsum, and ordered two AUMUND Samson® Material Feeders, each 17.1m long and with a capacity of 400 tph, as an ideal solution to receive natural gypsum from rear-tipping trucks.

NGC operates the largest gypsum quarry in the world, located outside Halifax, Nova Scotia. From here, natural gypsum will soon also be supplied to the Apollo Beach, FL, site, as its current supply of FGD gypsum will cease when the neighboring power plant no longer produces this by-product, after converting to natural gas. On arrival of the gypsum at the plant, two Samson® Material Feeders series MF-800 will receive the material at a capacity of 450 tph before transferring it for stockpiling. A dozer will then reclaim the material onto the 6 m long AUMUND Apron Feeder type BPB-250, capacity 250 tph, where it will feed into a crusher. The crushed gypsum will be received by the two 1600 series Samson® Material Feeders and subsequently fed onward into the manufacturing process. All four Samson® Feeders to be supplied to Apollo Beach are 13.3 m long.
