Structure of vertical rotary kiln Preheater

1. preheater body: it is the most important part to ensure that the material is pushed to 900 degrees Celsius. It is provided by the preheating room, suspension equipment and refractory brick liner (this item is not within the scope of equipment design and production) and other components. Some of the above structures are mostly metal components. Some materials have selected heat-resistant steel as needed, and heat-resistant steel can be in the range of 1000 ~ Work at a high temperature of 1100 degrees Celsius. In addition, the refractory brick lining structure has a novel design and good sealing performance, which ensures that the materials are evenly preheated in the Preheater and reach the preheating temperature.
2. Pushing equipment: It mainly includes the push head, structure and connecting rod, etc. The push head is made of heat-resistant steel forging or welding, and can accept high temperature. Thanks to the electronic control and hydraulic system, each hydraulic push rod can push materials in sequence according to the Active Control Program.
3. (rotary kiln equipment) Upper feeding system: first, it includes the upper silo and lower tube. The Blanking Method and structure can ensure the safety and sealing of the feed to the preheater, in this way, the external cold air cannot enter the preheater, and the feed can be continuously or intermittently fed by the rod valve.
