Refractory clay clinkers

- Jun 12, 2019-

Depending on the raw materials used and the production methods, refractory clay clinkers can be divided into two types: one is obtained by calcining hard clay blocks directly in a kiln; the other is using kaolin or hard clay. Fine grinding, homogenization, pressure filtration dehydration, drying, and finally burning in the kiln, is a high quality clay clinker. The main mineral phase of hard clay clinker is mullite, which accounts for 35% to 55%, followed by glass phase and cristobalite. Clay clinker is the main raw material of ordinary aluminum silicate refractories.
