KHD hands over a new grinding plant in Thailand
For Siam City Cement Public Co., Ltd. (SCCC) from Thailand, KHD Humboldt Wedag engineered and commissioned a new roller press-based raw meal grinding plant at SCCC’s factory 1 located in the Saraburi province.
With the new Comflex® grinding unit, the client is able to replace two outdated ball mill circuits. The new roller press-based circuit achieves the same production of 350t/h, but with a much less energy-demanding equipment setup. During the successful extended 72-hour performance test at the beginning of 2020, the new grinding unit met all targets regarding performance and product...
For Siam City Cement Public Co., Ltd. (SCCC) from Thailand, KHD Humboldt Wedag engineered and commissioned a new roller press-based raw meal grinding plant at SCCC’s factory 1 located in the Saraburi province.
With the new Comflex® grinding unit, the client is able to replace two outdated ball mill circuits. The new roller press-based circuit achieves the same production of 350t/h, but with a much less energy-demanding equipment setup. During the successful extended 72-hour performance test at the beginning of 2020, the new grinding unit met all targets regarding performance and product quality.
The Comflex circuit comprises the following proprietary KHD equipment:
Roller press RP M 18 – 200 / 180
Static coarse material separator VS 620
Static fine material separator LS 8600
System fan HKSK 236 / 346
Four product separation cyclones
The client SCCC appointed KHD with the contract because of the significantly reduced electrical energy demand of the main equipment. With a specific energy consumption of 13.36 kWh/t, the new roller press-based grinding circuit saves more than 8 kWh per ton compared to the old ball mill circuits. SCCC is now able to save almost 40% of energy while maintaining the same production volume. This converts to a reduction of annual energy costs of approximately € 1.5 million; a number that clearly indicates the significant return on investment of such a modernization project.
