0.5mm Tolerance Cement Rotary Kiln

Capacity: 3000tpd

Tolerance: 0.5mm

Diameter (m): 1.4-3.2

Cement rotary kiln belongs to the category of building materials and equipment, it is a kind of lime kiln. 0.5mm tolerance cement rotary kiln means that the allowable error of rotary kiln shell is within plus or minus 0.5mm.

Cement kilns are mainly used for calcining cement clinker, divided into two categories: dry process cement kilns and wet process cement kilns.


The cement rotary kiln operates at a heavy load and alternating slow speeds at high temperatures. The level of maintenance of its accessory equipment and the control of the thermal engineering system is related to the safety and efficiency of the rotary kiln operation. The maintenance focus of the transmission device is the lubrication, operating status, dynamic detection and meshing accuracy of the large and small gears; the installation accuracy of the supporting device determines whether the rotary kiln can operate safely and reliably.


The cement rotary kiln is composed of a cylinder, a transmission device, a supporting device for a supporting wheel and a retaining wheel, a kiln lining, a kiln tail seal, a kiln head, and a fuel device.


Wet Production Line

Cement kiln puts raw material into the kiln tail, raw material turns itself into cement clinker after a series of physical and chemical reactions because of the kiln’s tilt placement and its rotary capability. Put cement clinker into the cooling machine after it is ejected from the kiln head hood. Dry rotary kiln makes the raw material into raw powder, whose water content is less than one percent. The advantage is that it saves more energy than a wet rotary kiln. The disadvantage is that it may happen that the ingredient in mixed material is uneven.

Dry Production Line

Cement kiln turning raw into a slurry, whose water content is from 32 percent to 40 percent. The advantage of wet rotary kiln is that the good liquidity of slurry makes better evenness leading to a higher quality of clinker.

1.Dispose of hazardous waste
The cement rotary kiln has a high burning temperature, a stable state, and the waste is burned more thoroughly. The cement rotary kiln is under negative pressure during operation. It avoids the overflow of harmful gases when processing hazardous waste, and because the rotary kiln is well sealed, it Will cause dust pollution, which is conducive to environmental protection.

In addition to forging cement clinker, the cement rotary kiln is also used for calcining clay, limestone and slag drying. In the production of refractory materials, the rotary kiln forging raw materials is used to stabilize the size, increase the strength, and then process the shape. In non-ferrous and ferrous metallurgy, metals such as iron, aluminum, copper, zinc, tin, nickel, tungsten, and chromium are smelted using rotary kilns to sinter and roast ores, concentrates, intermediates, etc. For example, it is used in aluminum production to roast aluminum hydroxide into alumina; it is used in ironmaking to produce pellets for blast furnace ironmaking; foreign “SL / RN method” and “Krupp method” use it for iron ore Direct reduction is carried out; it is used to extract tin and lead by the chlorination volatile roasting method.
