Two kinds of materials, desulfurizer and reducing agent, are put into the quantitative hopper, and the quantitative hopper sends the materials to the drying chamber through the conveyor according to the weight ratio of the two materials to dry and mix the two materials.

Its technical performance and operation determine the quality, output and cost of enterprise products to a great extent. "As long as the kiln turns, there will be tens of millions" is a vivid description of the importance of the rotary kiln in production. In the building materials industry, in addition to calcining cement clinker, rotary kiln is also used to calcine clay, limestone and slag drying

Rotary kiln refers to rotary calcining kiln (commonly known as rotary kiln), which belongs to building materials and equipment. Rotary kiln can be divided into cement kiln, metallurgical and chemical kiln and lime kiln according to different materials. Cement kilns are mainly used to calcine cement clinker, which are divided into dry cement kilns and wet cement kilns.
