Pneumatic conveying systems utilize airflow as a power source to transport powdered or granular materials from one location to another via pipelines, making them essential equipment in modern bulk material handling. These systems are widely used in industries such as cement, chemicals, food, plastics, new energy, and pharmaceuticals, and are characterized by high conveying efficiency, a high degree of automation, and environmental friendliness. Depending on the conveying distance, material properties, and process requirements, the system can be designed as a positive-pressure or negative-pressure conveying system, or as a dilute-phase or dense-phase conveying system. SDCAD provides high-quality, efficient, reliable, environmentally friendly, and energy-efficient material conveying solutions to major cement plants and mining companies.
