Natural Gas Rotating Dryer Copper Slag Rotary Dryer Mineral Slag
It adopts direct flow heating with heat source from firing unit. The material to be dried is pushed back immediately by spiral board after going in the shell from feeding tank or feeding chute. Because the drier is installed in an inclined position, material flows to the back end under gravity and rotation force.

Slag Cement
Slag cement, originally known as granulated blast-furnace slag, begins with the production of iron. The heart of the process is the blast furnace that refines iron ore into iron. The ingredients are heated to nearly 1500 degrees Centigrade to form two components: iron and molten slag. The iron is used to produce steel, and the molten slag is

Producing cement emits massive amounts of carbon — but there
2 The cement, water and aggregate are blended into a thick slurry (or delivered that way in a cement mixer truck), poured into a mold, and left untouched for days or weeks while water and cement react to form concrete. This process also locks in the aggregate, which is included for strength and bulk, along with any reinforcements like steel rebar.
