Rotary kilns In modern cement plants, cement production is a continuous dry process, where the rotary kiln plays a key role. In the first step raw materials such as limestone, clay, sand, and iron ore are crushed in a cone mill and dried.The final induration is accomplished in a rotary kiln, wherein the principal heat transfer mechanism is radiation from the system's main burner,Infrared pyrometers are often used to monitor shell temperature and identify hot spots before they become a problem. Rotary Kilns also have cylindrical steel castings, known as tyres, attached to the shell, which obstruct the shell monitoring system. If a hot spot forms under a tyre, then the instrument will not detect it.

Applicable industries: Energy & Mining, Video outgoing-inspection: Provided, Machinery test report: Provided, Warranty of core,Rotary kilns consist of a rotating cylinder inclined at an angle of 3 to 4 degrees to the horizontal. Limestone, chalk or Dolomite is fed into the upper 'back end', and fuel plus combustion air is fired into the lower 'front end'.The product is then discharged from the kiln into a cooler, where it is used to pre-heat the combustion air.

The rotary kiln provides constant mixing of the pellets, bringing all the pellets to the same temperature. In a straight grate, the pellets at the top of the bed are "over cooked" and those at the bottom are "under cooked". Higher quality means fewer fines, better reducibility and less variation in compression strength. Ported kiln operation,The barrel of rotary kiln for ceramsite has a slope of 3%-4% with a horizontal plane. The kiln body is immobilized in wheel gear by two-wheel band. The principle of rotation is that inverter motor drives the pinion to rotate through reducer and its associated coupling. Then gears mesh with fixed large ring gears in the kiln.
