Refractory Castable for Garbage Incinerator
Household garbage can be seen everywhere, especially garbage incinerators is very important. RS in the production of waste incinerator with refractory castable type industrial waste incinerator with rotary kiln with refractory castable, CAO garbage incinerator with refractory castable, the grate type incinerator with refractory castable. Next I will introduce you some refractory castable about these three incinerators.
