Powder materials including fly ash, cement and coal powder are widely used in building material manufacturing. Conventional conveying equipment usually suffers from dust spillage, frequent breakdowns and heavy maintenance workload. Large sealing gaps allow fine powder to escape easily. Continuous operation accumulates dust inside workshops, which fails site environmental requirements and causes raw material loss.
Standard conveyors have limited throughput. Under continuous mass-production conditions in building material plants, uneven feeding and blockages often happen. Frequent shutdown for cleaning and inspection disrupts production cycles and increases labor and spare-part costs. Sealing performance and continuous operational stability become key evaluation criteria for equipment selection in building material projects.
The LS series screw conveyor adopts fully enclosed shell to realize sealed transportation for powder and granular building materials. The structural design restrains dust overflow and material leakage to meet workshop environmental standards. Its compact frame supports fixed installation on production lines without occupying excessive working space.
LS series provides a complete range of models with maximum conveying capacity up to 520m³/h (Source: official LS parameter datasheet). It supports long-hour continuous operation for large-scale building material production lines. The external bearing with centralized oil lubrication structure prevents dust intrusion and component abrasion, extending trouble-free running time.
Three key indicators need assessment during model selection: material moisture content, hourly throughput and conveying distance. LS single-shaft screw conveyors are preferred for horizontal or low-inclination transport of cement and fly ash. Multi-unit serial connection is available for long-distance conveying to maintain steady throughput.
Wear-resistant lining can be equipped if materials contain hard particles, protecting shell from long-term scouring, cutting maintenance frequency and fitting year-round nonstop production of building material plants.
With sealing structure against spillage, high throughput and low-maintenance design, LS screw conveyors target typical pain points including dust emission, material waste and unexpected downtime in powder conveying. It features wide working condition adaptability and serves as mature, reliable standard bulk material handling equipment for building material production lines.
