The refractory cement is a type of newly developed material that has excellent heat-resistant performance and is widely used in the industrial field. The most common refractory cement is calcium aluminate cement (or high alumina cement), which is a kind of hydraulic cementitious material made by grinding the aluminate cement clinker.
The main difference between separate and co-grinding of blended cement is the fact that co-grinding occurs interaction among the milled components. These interactions may speed up milling process, or on the contrary to slow it down. It depends on grindability of the components. Separate grinding and subsequent homogenization is more common.
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 >> Details
