Rotary kiln description: Rotary kiln is a pyroprocessing device used to raise materials to a high temperature (calcination) in a continuous process. Materials produced using rotary kilns include: Cement, Lime, Refractories, Metakaolin, Titanium dioxide, Alumina, Vermiculite, Iron ore pellets, etc. Rotary kiln is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly about its axis. The material to be processed is fed into the upper end of the cylinder. As the kiln rotates, material gradually moves down towards the lower end, and may undergo a certain amount of stirring and mixing. Hot gases pass along the kiln, sometimes in the same direction as the process material (co-current), but usually in the opposite direction (counter-current). The hot gases may be generated in an external furnace, or may be generated by a flame inside the kiln. Such a flame is projected from a burner-pipe (or "firing pipe") which acts like a large bunsen burner. The fuel for this may be gas, oil or pulverized coal. Rotary kiln is often compared to an industrial sized oven which is designed to withstand extreme temperatures as needed for the smelting process of all types of hydraulic cement.  Calcium carbonate reacts with materials that include silica that in turn forms a calcium silicate. As very high temperatures are needed to make this process possible; it is only made possible through the innovative design of heavy duty cement rotary kilns. Rotary kiln should only be purchased from a reputable source such as a professional cement rotary kiln supplier.  This is due to the fact that the process under which a rotary kiln operates is extremely dangerous and the use of a lesser quality rotary kiln will most definitely lead to injury, death and large losses for the company due to kiln failure. Rotary kiln usage: Rotary kiln can be divided into cement kiln & lime kiln according to its function. Rotary kiln advantages: high efficiency, low consumption, environmental protection, energy saving Technical performance of rotary kiln: Size(m) Capacity(t/d) Inclination(%) Supports(pc) Damper Type Kiln Rotation Speed Main Drive Auxiliary Drive Main Drive(r/m) Auxiliary Drive(r/m) Motor Power(KW) Reducer (Overall Ratio) Motor Power (KW) Reducer (Overall Ratio) φ2.8/2.5×44 300 3.5 3 Mechanical 0.445-2.22 4.75 55 49-63 4 40.44 φ3×48 600-700 3.5 3 Mechanical/ Hydraulic 0.676-3.38 9.36 100 50 7.5 14 φ3.2×50 1000 3.5 3 Hydraulic 0.36-3.57 6.5 160 40 15 31.5 φ3.3×50 1200 4 3 Hydraulic 0.36-3.57 5.61 160 40 11 31.5 φ3.5×54 1500-1800 4 3 Hydraulic 0.39-3.9 7.66 220 28 18.5 45 φ4×60 2500 4 3 Hydraulic 0.41-4.07 8.2 315 22.4 22 45 φ4.3×64 3500 4 3 Hydraulic 0.4-4.0 7.93 400 31.5 30 45 φ4.8×74 5000 4 3 Hydraulic 0.35-4 8.52 630 42.226 55 28 φ5.0×74 6000 4 3 Hydraulic 0.35-4 7.58 710 28 55 45 φ5.6×87 8000 4 3 Hydraulic Max4.23 8.7 800 23.901 90 35.795 φ6.0×95 10000 4 3 Hydraulic Max5 9.2 950×2 26.646 132 35.795 Service: Jiangsu Pengfei Group is a professional manufacturer of rotary kiln, vertical roller mill, roller press, ball mill for over 40 years.
