Crusher/Pulverizer for Diamond Mining Delivered to Namibia

 In February, EarthTechnica Co., Ltd., a joint venture of Kawasaki and Kobe Steel, Ltd., shipped a crusher/mill for a diamond recovery plant on the west coast of Namibia to Namdeb Diamond Corporation (Pty) Limited, a joint venture of the Namibian government and De Beers Centenary AG, the world’s largest diamond producer. Bateman in South Africa, an engineering company, will be in charge of this equipment assembly and installation, which is scheduled to be completed in October 2004.

 Namdeb has been producing diamonds the conventional way: screening beach sands, washing them and performing gravity separation. It has become increasingly difficult to find beach deposits after mass excavations, however, and the company is now looking into the layers underneath the sands. But because there are alternating layers of rock, clay, sand mixed with clay and a mixture of sands and seawater, mining is difficult to perform without more advanced facilities.

 EarthTechnica’s crusher/mill is vital equipment for mining diamonds in such densely layered strata. It crushes/pulverizes the mined material in three stages using special technology for preferential crushing, and extracts cleaned material of 1.4mm to 6.0mm in size with minimal damage to the diamonds.
