Lime rotary kiln outstanding advantages:

1. Calcium carbonate rotary kiln shell design takes full account of the deflection of the support of the cylinder body, extending the fire brick and casting life.

2. Calcium carbonate rotary kiln adopts large-diameter and small-diameter-diameter bracket roller bearings to improve reliability. Bearings are self-aligning bearings.

3, calcium carbonate rotary kiln is a new type of open gear cover seal, sealing effect is good.

4. Spring-laminated flexible seals, double-layer spring seals increase the insulation layer design, which helps to improve the reliability and service life of calcium carbonate rotary kiln.

Rotary kiln working principle:

The kiln body of the calcium carbonate rotary kiln forms a certain angle with the horizontal line, and the motor rotates through the reducer and the large gear around the cylinder body. The primary air used for fuel and combustion is sent to a calcium carbonate rotary kiln through a burner that extends into the kiln tube. The secondary air used for combustion is entered from the cooling cylinder and is warmed up before entering the kiln through the hot smoke chamber. The hot air generated by the combustion is sent to the chimney by the kiln body, dust collector, and dust collector. The calcined raw material is fed to the kiln through the kiln tail and the material is moved forward by the rotation of the inclined kiln body. At the same time, the calcined raw material and the combustion heat gas from the kiln head of the calcium carbonate rotary kiln are heated and reach the reaction temperature, and then fall from the kiln head into the cooling cylinder. The movement of the material in the cooling cylinder is also based on the cylinder. The inclination and rotation are performed.

The lime rotary kiln shall be operated in accordance with the regulations, and special attention shall be paid to: after the drying of the kiln stops, the waste residue from the kiln shall be cleaned to prevent the material from falling after incineration. The key to burning is to average the flames, add the fabrics on average, and discharge the materials according to the size of the raw materials. It is appropriate to send the wind to apply the wind, and strictly control the air volume in the initial stage. After that, the air volume should be appropriately improved every time. Kiln temperature promotion speed is slow, generally 20-30 days can be adjusted in place. The staff in each position must be careful and co-worked, so that they can be properly diligently unloaded and grounded, multi-point fabrics or continuous feeding should be correct, mixing should be average, the ratio should be firm, and the wind should be appropriate.
