Local estimates suggest domestic grinding capacity is expected to rise by 14 per cent in 2021. The gap between production and demand remains wide as Sri Lankan cement consumption totals approximately 8Mta. Industry development
Grinding takes place in huge mills, where ro-tating steel balls crush the material until the required grain size distribution is reached. The produced cement is then 3 conveyed to different silos according to grade before being packaged and shipped to customers.
