The use of electrical power in the operation of a new cement unloader for US-based Ozinga means the building materials supplier can operate its Chicago terminals with a lower environmental impact and save on energy costs. By Van Aalst Bulk Handling BV, The Netherlands.

Building materials supplier Ozinga needed a new portable cement unloader to serve its Northside and Chinatown terminals in Chicago, Illinois, USA. At both sites river barges transporting 1500t of cement have to be unloaded before being conveyed into silos on site. At the Northside terminal, the total conveying distance is 123m (405ft), of which 38m (125ft) is vertical. The Chinatown terminal has four different transfer lines, with the longest having a conveying distance of 126m (415ft), of which 30m (98ft) is vertical.
