Rotary kiln - Wikipedia

OverviewHistoryPrinciple of operationConstructionOther equipmentSee alsoSources and further readingThe rotary kiln was invented in 1873 by Frederick Ransome. This is made from rolled mild steel plate, usually between 15 and 30 mm thick, welded to form a cylinder which may be up to 230 m in length and up to 6 m in diameter. Upper limits on diameter are set by the tendency of the shell to deform under its own weight to an oval cross section, with consequent flexure during rotation. Length is not necessarily limited, but it becomes …Wikipedia & 183; CC-BY-SA 许可下的文字

Information on Kiln Power and Voltage Big Ceramic Store

120 V kilns usually go up to 30 amps maximum. 208 V and 240 V Kilns are designed for 30, 40, 50 amps or more. At 48 amps and above, kilns do not come with plugs; instead they must be wired directly into your power supply. This is because good electrical design practice limits the amperage requirements of a kiln to 80% of the circuits rating.
