New Type Activated Lime Rotary Kiln/ Heavy Equipment

Activated lime rotary kiln
Lime rotary kiln is aimed at the Calcination Characteristics of limestone. The main equipment used in lime production line is mainly used. The new type rotary kiln with active lime is developed on the basis of absorbing and referring to the same type of rotary kiln both at home and abroad. This type of rotary kiln (optional vertical preheater and vertical cooler energy-saving rotary kiln calcination system) has high rate of calcination, completely uniform quality and good quality, large capacity, operation rate is high, energy saving, simple operation and long service life by using the raw material, is also in line with the national energy environmental protection and energy saving industrial policy. For cement, building materials, metallurgy, refractory materials, environmental protection, lime production line, and other industries of calcined limestone.
Working principle
The material through the kiln (high-end) chute feeding in the kiln, as the tilt cylinder and slow rotation, the material side along the circumference side along the axial direction by the rolling kiln (high-end) to the kiln head (low end) * movement; and fuel from the kiln head (low-end) combustion burner by spraying in the kiln, heat radiation, convection, conduction to material, material after calcination in the process of moving, unloading from the kiln head, high temperature flue gas from kiln tail into the dust removing system of kiln.technical parametercapacity (t/h)Size of kiln bodyproductpreheatercoolerFuelHeat consumption

The above model is the product data, the user can order special specification equipment according to the material category, special requirements, production and other conditions.Structure composition
The lime rotary kiln is mainly composed of a transmission device, a supporting wheel supporting device, a supporting wheel supporting device, a cylinder body, a kiln head, a kiln tail and a sealing device, etc. the main structure features of the rotary kiln are that the main structure of the rotary kiln is the supporting device, the supporting device of the supporting wheel, the supporting device of the supporting wheel, the kiln head, the kiln end and the sealing device, etc.:
1,2 ~ 3, the whole kiln installation fulcrum, easy to ensure contact with the roller kiln surface parallel to the axis of the cylinder
There is a specific gap. And the tyre and the cylinder, to ensure that the cylinder thermal expansion after the wheel hoop plays a role in strengthening the cylinder cylinder
2, Ring gear split combined structure, with the spring plate and the cylinder body is easy to install, and the transmission is stable and reliable
3, The supporting device adopts rolling bearing (there are very few sliding bearings), so that the roller bearing structure is greatly simplified, can reduce useless power loss in the process of kiln operation, makes more convenient maintenance and repair
This, in order to facilitate the installation, debugging, and can still ensure the disc kiln operation in the maintenance of the main transmission system or other abnormal conditions, to prevent the kiln body deformation occurred during the cooling process, a slow disk kiln body
4, According to the type of kiln used in mechanical or hydraulic blocking wheel, both of which are of high precision and reliability, at the same time so that the roller and tyre wear uniform cylindrical in the width direction, and convenient adjustment
5,Kiln head and tail seal with the elastic flake radial contact seal, can well adapt to the dynamic partial pendulum and axial cylinder shape error and the kiln, the sealing performance is more excellent. *, according to the type of kiln used in mechanical or hydraulic blocking wheel, both of which are of high precision and reliability, at the same time so that the roller and tyre wear uniform cylindrical in the width direction, and convenient adjustment;
6, Kiln head and tail seal with the elastic flake radial contact seal, can well adapt to the dynamic partial pendulum and axial cylinder shape error and kiln, the more excellent sealing performance and higher reliability.
Outstanding advantage
It is heated evenly: limestone is heated evenly, the product quality is stable, and burning rate is low, especially for the high activity of calcined lime
This product is stable: in the calcined materials can make the material is heated evenly, the product quality is stable, suitable calcining high activity of lime
This transmission system: main drive system adopts AC frequency conversion technology, new energy saving and environmental protection, and wide range of speed, high efficiency, high precision and stable operation speed
7, Tugboat device: base single wheel support device and wheel supporting device of welding completed, after vibration aging treatment to eliminate welding stress, can improve the installation accuracy and reliability
By optimizing the structure: according to the requirements of the characteristics and calcining process of limestone, the kiln head and tail section of the overall structure optimization design, solves the common rotary kiln kiln recycle and dust leakage, conveying more smooth and natural
