Grinding and homogenization

Биднээс асуу

Grinding and homogenization. The grinding process takes place in a raw mill to reduce the particle size of the components to a typical value of 10-15 % residue on a 90 um sieve. The output of the grinding process – called ''raw meal'' – is transferred to a homogenization silo before the clinker manufacturing process. << Previous Next >>.
