The device is the complete set of system equipment, which uses pressed air as the power and makes the solid granular materials conduct dry method conveying through the closed pipe. The systems generally include gas source, transmitter, pipe and valve, control and silo five parts. The advantages are: the materials are entirely sealed in the conveying process; the climate and environmental impact is small; working conditions for workers are good; materials will not be damp, defaced or mixed with impurities; simple equipment, compact structure, flexible layout, covering smaller area, and low equipment costs; can conduct some process (such as crushing, drying, grading) operations at the same time; easy centralized control; can realize automation and improve transmission capacity. In addition to the materials that are fragile, strong adhesion, large grinding and carving, corrosive and easy to cause chemical changes are required special handling, the general loose materials can be conveyed. It is widely used in coal, chemical industry, casting, coal-fired power station, medical, building materials, food, port and other industries.

  Manufacturing features: It is designed according to the nature (particle size, proportion), conveying distance, climbing high, scene situation, productivity, conveying ways (continuous or intermittent) of the conveying materials offered by the customers, and selects suitable equipment. It is non-standard product of tailor, single design, low-volume, and multi-species.
