Rotary Kiln

Characteristic

Rotary kiln refers to rotary calcining kiln (commonly known as rotary kiln) and belongs to building materials equipment category. According to different processing materials, rotary kiln can be divided into cement kiln, metallurgical chemical kiln and lime kiln.

Cement kiln is mainly used for calcination of cement clinker. It is divided into dry cement production kiln and wet cement production kiln.

Metallurgical chemical kiln is mainly used in metallurgical industry lean iron ore magnetization roasting, chromium, nickel ore oxidation roasting, high alumina bauxite mine roasting in refractory plant and clinker, aluminum hydroxide roasting in aluminum plant, chromium ore sand, chromium ore powder and other minerals roasting in chemical plant.

Lime kiln (i.e. activated lime kiln) is used for roasting active lime and light-burnt dolomite used in steel plants and ferroalloy plants.

Outstanding Advantages

The axial movement of cylinder body is flexible and controllable

The kiln barrel is welded by high-quality steel coil, it is supported on the bearing device of the 2~7 retaining plain bearing by the belt. Mechanical or hydraulic gear is equipped in one or several gear support devices, so customer can control the axial movement of the cylinder flexibly.

Flexible speed

The transmission device makes the cylinder rotate at the required rotational speed by the gear ring located in the middle of the barrel and the rotational speed can be adjusted flexibly.

Easy installation and maintenance

The larger kiln is equipped with an auxiliary transmission that enables the cylinder to rotate at a very low rotational speed to meet the requirements of installation and maintenance.

Good sealing performance

The cylinder feeding side (tail) and discharging side (head) are equipped with a reliable kiln tail and kiln head sealing device. So that it can effectively prevent the cold air entering and the flue gas dust overflowing out of cylinder body.
