The ceramsite sand rotary kiln is an industrial equipment used to produce ceramsite. It converts raw materials such as clay, shale, and fly ash into lightweight and porous ceramsite through high-temperature calcination process. These ceramsites have good physical and chemical stability and are widely used in construction, gardening, environmental protection and other fields as lightweight aggregates or filter materials. The ceramsite sand rotary kiln has the advantages of stable operation, high output, energy saving and environmental protection, and is a key equipment for modern ceramsite production.

What should be paid attention to when mixing raw materials for ceramsite sand rotary kiln?

1. Particle grading. Mixing raw materials of different particle sizes can optimize the stacking density and increase the filling rate of the ceramsite sand rotary kiln, thereby affecting the thermal efficiency and production capacity of the kiln.

2. Moisture control. The moisture content of the raw materials will also affect the quality of ceramsite and the heat consumption of the kiln. Too high moisture content will lead to increased heat consumption, while too low moisture content may affect the molding and sintering quality.

3. Raw material composition. The raw materials mainly include clay minerals, fly ash, shale, urban solid waste, industrial by-products, etc. Different raw materials contain different silicates, aluminates, oxides and other components. The proportion should be determined according to the required performance indicators of ceramsite. The proportion needs to consider the content of various oxides such as SiO₂, Al₂O₃, Fe₂O₃, CaO, MgO, and the influence of impurity elements such as potassium, sodium, sulfur and phosphorus in the raw materials.

4. Chemical activity. The chemical activity of various raw materials is different, and their reaction ability and melting state at high temperature are also different. Reasonable matching is required to ensure the normal sintering and expansion of ceramsite in the kiln.

How to calculate and predict the output of ceramsite sand rotary kiln?

1. Monitoring and adjustment. In the actual production process, the temperature distribution, material movement state, exhaust gas composition, etc. in the ceramsite sand rotary kiln are monitored in real time, and the raw material ratio and combustion control are adjusted in time to maintain stable output and product quality.

2. Theoretical output calculation. According to factors such as kiln size, kiln filling rate, material residence time, rotation speed, etc., combined with the physical properties of raw materials and chemical reaction rate, the amount of ceramsite that may be produced per unit time can be theoretically calculated.

3. Practical experience data. In actual production, the actual output of the kiln is statistically calculated through historical data, and the output prediction model is established by combining parameters such as raw material consumption, energy consumption, and kiln operation efficiency.
