External circulation technology for VRM raw meal grinding

04 July 2019, Published under Cement News

The pressure differential of a traditional vertical roller mill (VRM) system for raw meal grinding is high, with the fan accounting for about 45 per cent of power consumption. Sinoma International Engineering has developed external circulation VRM technology for raw meal grinding, whereby materials are transported by elevator instead of gas flow, leading to reductions in pressure differential and power consumption. By Du Xin, Nie Wenhai and Chai Xingteng, Sinoma International Engineering Co,...

Combining forces

25 January 2017, Published under Cement News

Upgrading cement grinding systems offers both process and commercial benefits. The use of a high-pressure grinding roll in semi-finish grinding mode significantly reduces specific energy consumption and improves production capacity. But this type of grinding system requires two types of air classifiers, which usually ties up additional investment and space. Therefore, Germany-based Maschinenfabrik Köppern has developed a compact air classifier that enables grinding system upgrades by integra...

High-efficiency cement grinding

17 September 2012, Published under Cement News

For more than a quarter of a century the ThyssenKrupp Polysius’ POLYCOM® high-pressure grinding roll (HPGR) has been in successful operation. More than 65 of the presses are working in highly-efficient clinker grinding systems around the world. By using the POLYCOM as a stand-alone grinding machine (finish grinding circuit) a reduction in specific power consumption of around 50 per cent compared to conventional ball mill circuits is achievable. The high compression stressing applied inside t...
