The Composition and Calcination of Rotary Kiln
Rotary kiln refers to rotary calciner, belonging to building material equipment. According to different materials in it, the rotary kilns can be classified into cement kiln, metallurgy chemical kiln and limestone kiln.
At this second, people must appropriately reduce the coal volume in kiln head, and concurrently, individuals have to correctly minimize the internal-flow wind even though improve the external-flow wind so as to elongate the flame and reduce way too substantial temperature in rotary kilns.
Cement kiln is mainly used for calcining cement clinker, and consists of dry type cement production kiln and wet type cement production kiln. Metallurgy chemical kiln is used in steel plant, refractory plant or chemical plant, and limestone kiln is applied for roasting active lime or light burned dolomite in steel plant and ferroalloy plant. In cement rotary kiln, the cement raw material is calcined. However, the raw material must be prepared firstly with coal crushed.
In the true practice, if men and women find out the burning-zone substance is sticky, then began height is comparatively higher, the rotation of content just isn’t adaptable, sometimes, it will have pie-shaped materials, every one of these prove that the temperature in the rotary kiln is simply too substantial.
If men and women need to shorten the flame, they are able to centralize the high-temperature location, or when high quality of coal is comparatively poor, the burning velocity is comparatively sluggish; men and women can correctly enlarge the internal-flow wind but decrease the external-flow wind. If top quality of coal is sweet or perhaps the kiln coating is just too slender, the floor temperature of simplified kiln is comparatively large, in this scenario individuals desire to elongate the flame, and they ought to enlarge the external-flow wind nevertheless decrease the internal-flow wind.
