Nanjing Air Conveying Systems Ltd.

We design the pneumatic conveying system and make the conveying components. The pneumatic conveying system are considered, such as the type of material used, conveying distance, system constraints including feeding and discharging, health and safety requirements, and the need for continuous or batch conveying.

Specializes in pneumatic conveying of dry bulk solids materials for the processing industries.

Some common solids as flour, sugar, cement and many more, can be suspended and transported in air - referred as pneumatic conveying. A pneumatic conveying system may transport solids up to approximately 50 mm size. The powder or solid must be dry, with no more than 20% moisture and not sticking.

In a pneumatic conveying system, most of the energy is used for the transport of the air itself. The energy efficiency of a pneumatic conveying plant is therefore relatively low, but this is often outweighed by easy handling and, in well designed systems, dust free solutions.

In general the length of a pneumatic system should not extend 300 m for each pneumatic unit. The products can be conveyed over long distances by connecting the systems in series.

There are three basic designs of pneumatic transport systems:
Dilute phase conveying at a high gas speeds (20 - 30 m/s)
Strand conveying at a limited gas speeds (15 - 20 m/s)
Dense phase conveying at a low gas speeds (5 - 10 m/s)

Pneumatic systems can operate with both positive and negative pressures - vacuum. The working pressure should not extend 40 kN/m2.

The maximum temperature rise during pneumatic compression is seldom above 5oC, which makes pneumatic transport systems suitable to sensitive products as medicines, food or similar

Full system manufacture also takes place with complete engineering and turnkey services

Installation and Commissioning is performed by trained field technicians with a well disciplined procedure of system pre start checks and close interaction with the end user. User training in maintenance and system operation is provided in detail.

Record keeping is very comprehensive and all aspects of a system performance are maintained in a central electronic data base. A similar record of replacement parts for each system is also maintained for review to check overall system performance and economy.

Maintenance Retraining is offered for office based tutorials and hands on practical courses.
