mineral sector, and that competition is becoming more intense on the mill sales market. The Chinese companies CNBM. Sinoma (Cem Teck), CITIC and particularly Chengdu Leejun have meanwhile entered the roller press market. The last– mentioned company has already supplied more than 300 units in China alone. They have received about 20 orders from customers outside China. While these Chinese vendors are said to still have their deficits, particularly in respect of documentation and service, the established vendors all provide a good level of service and thus assure the reliability and availability of their products. Prospects Vendors of mills are now facing increasingly stiff competition in the cement industry. This is due firstly to the large number of technically mature plant solutions and secondly to the new competitors entering the market, especially from China. The established mill manufacturers are trying to maintain their technological competitive advantage by introducing various innovations. These include improved drive concepts, modular configuration of the grinding units better wear protection, simpler maintenance and high-quality service. Chinese venders are keen to INVITATION FOR CONTRIBUTIONS obtain further reference installations outside China. Manufacturers find it difficult to establish totally new mill concepts on the market, even if they offer significant benefits. This was demonstrated by the introduction of the Horomill, and the BETA mill could suffer the same fate. All in all, it may be presumed that single-stage grinding processes with vertical mills or roller presses will continue to expand their market shares at the cost of ball mills.
