Siam Cement Public Co Ltd (SCG) has contracted Loesche to deliver a new vertical roller mill (VRM) of the type LM 56.3+3 CS for its Kaeng Khoi cement plant.
 
The mill will produce medium-fine cement qualities and is designed for grinding clinker, gypsum and limestone. SCG will be able to quickly switch between different products and qualities with the new mill enabling the company to produce a wide range of different cement types, as well as varying product finenesses, thus making it easier to place them on changing markets. With the classic roller presses and ball mills predominantly used at SCG, this would take a long time.
 
The flexibility that will be available in future for manufacturing the various different cement types also means greater profitability for SCG. The cement quality can be improved quickly and efficiently and adapted to the requirements of the market.

A more energy-efficient production of the different cement types is also possible with the new Loesche mill. Compared to roller presses or ball mills, the achievable efficiency gains in electrical energy lie between 15 and 40 per cent depending on the cement quality, claims Loesche.
