Sedgman undertook initial design through to commissioning of a 700 t/h coal handling and preparation plant (CHPP) on a greenfield site. New Hope again engaged Sedgman for design through to commissioning of a stand-alone 350 t/h plant (CHPP2) adjacent to New Acland CHPP1. Sedgman is currently undertaking an upgrade to 550 t/h of CHPP 2. At the time of commissioning, the initial plant was the largest in the Surat and Clarence Moreton Basins. Sedgman designed the plant to successfully process multiple thin-seamed coals with potential for high dilution levels. To date Sedgman has completed the projects LTI-free and on time.

Sedgman designed both CHPPs to use wet crushing before processing to more efficiently manage the high clay resource and improve clay breakdown typically experienced in local coals. The primary process involved the combination of a jig to reduce stone dilution in feed with dense medium cyclones and spirals. Sedgman designed all conveyor systems, bins, stockpiles and the coal preparation plant. This included all mechanical, civil, structural, electrical, controls and process engineering requirements.
