A rotary kiln is a device that supplies tremendous amounts of heat in order to change the chemical composition of an object.
Flotation machine (also called flotation separator) is applicable for the separation of nonferrous metal and ferrous metal and nonmetal, such as fluorite and talc.
Cement rotary kiln is the main equipment of calcining the cement clinker. The characteristics of a rotary kiln are simple structure, convenient and reliable control of the producing process.
The sand washer is a kind of highly efficient sand washing plant, taking the advanced techniques and the domestic physical conditions together into consideration.
Also, the production process of greenconcretedoesn’t lead to environmental destruction such asusing excessive energyin its production and produces less CO 2 than conventionalconcrete. Hence, thegreen concreteis also known as eco-friendly concrete or environmentally friendlyconcrete.
