Rotary kiln matters as important burning reaction equipment

Since the rotary kiln was regarded as the cement high-temperature torch burning reaction equipment, its specifications experienced various development processes. With the advent of the preheater technology and the constant improvement and the improvement and application of the dry prehomogenized technology of the raw materials, the rotary kiln with the characteristic of dry production can again return to its original development track.
The rotary used for burning cement clinker appeared accompanied by the dry process production way. However, since the burning process of the cement production was not mature at that time. The most serious problem is that the uniformity is very poor.
According to the stress analysis of the tyre, the tyre is affected by the high temperature when the cylinder of the rotary kiln works under 350? to 380 ?. The deformation displacement in the vertical direction of the tyre is the most. Under the action of the load, the highest point of the wheel band moves down and the lowest point of the wheel band moves upward. The wheel band is crushed for deformation, which is similar to a flat oval. When the wheel band and cylinder pad are badly worn and the gap between the wheel band and the pad becomes large, the deformation of the wheel band will increase with the increasing ovality. It is easy to cause the rising temperature of the axis of the ridding wheel.

Since the preheater completes a lot of heat exchange and the decomposition of partial of materials, the length of the rotary kiln is greatly reduced so that the heat consumption of the dry production is lower than that of the wet process, which greatly improves the heat load and operating conditions of the rotary kiln and provides large-scale and reliable technical support for the cement industry. The decomposition technique outside the kiln promotes the continuous optimization and improvement of the preheater, calciner structure and the operating parameters. The new generation of rotary kiln produced by Henan Hongxing Mining Machinery has the reasonable design and high working efficiency, which is warmly welcomed by a lot of customers.
