1. What types of materials are suitable for pneumatic conveying?
Pneumatic conveying is suitable for powders and granular materials with good flowability, such as cement, fly ash, lime powder, table salt, flour, plastic pellets, and chemical powders. The specific solution must be determined based on the material’s density, particle size, and moisture content.
2. What is the difference between positive-pressure and negative-pressure conveying?
Positive-pressure conveying uses compressed air to push the material to its destination and is suitable for long-distance conveying; negative-pressure conveying uses vacuum suction to transport the material and is better suited for multi-point material collection and applications where dust leakage must be prevented.
3. What is the maximum conveying distance?
Depending on the material properties and conveying method, pneumatic conveying distances can range from tens of meters to hundreds of meters. For large-scale projects, we can achieve stable conveying over even greater distances through system optimization.
4. Does the conveying process damage the material?
For fragile particles or special materials, we can use low-speed dense-phase conveying technology to minimize collisions between the material and the piping, thereby reducing breakage rates and ensuring product quality.
5. Is the energy consumption of a pneumatic conveying system high?
The system’s energy consumption primarily depends on the conveying distance, conveying volume, and material properties. Through proper equipment selection and optimized design, energy consumption can be effectively reduced, and overall operational efficiency improved.
6. Are pipeline blockages common?
Under normal circumstances, pipeline blockages do not occur, unless the conveyed material is changed arbitrarily and the material is highly viscous and prone to sticking to the pipe walls; however, such situations are extremely rare.
SDCAD effectively prevents pipeline blockages through scientific pipe diameter design, reasonable air-to-solid ratio calculations, and an automatic control system. Additionally, the system can be configured with material blockage alarms and automatic protection functions.
