Ramming mass is a refractory material made by ramming process. It is composed of various aggregates, binders and additives. We supply different types of ramming mass, including acidic ramming mass, neutral ramming mass and basic ramming mass, as follows:
KERUI Acidic ramming mass: silica ramming mass and quartz ramming mass, etc.;
KERUI Neutral ramming mass: corundum ramming mass, mullite ramming mass and aluminum ramming mass, etc.;
KERUI Basic ramming mass: magnesia ramming mass, magnesia aluminum ramming mass and aluminum magnesia ramming mass, etc.;
