The material conveying fan features a reasonable and durable structure, offering stable and reliable performance, high efficiency, strong adaptability to various working conditions, low noise levels, and easy maintenance. It is an indispensable specialized equipment for wood, bamboo, furniture, plywood, and particleboard factories.
Bulk material handling methods can be broadly categorized into two major types: intermittent transport and continuous transport. Continuous transport, in turn, can be further divided into mechanical transport and fluid transport. Since traditional mechanical conveying systems—such as belt conveyors, scraper conveyors, chain conveyors, and screw conveyors—often suffer from high costs, high energy consumption, large footprints, and frequent material losses and dust generation during powder material transportation, fluid pipeline transport offers several advantages: it boasts high conveying efficiency, requires a small installation area, has relatively low costs, is easy to maintain, and features a highly sealed system with minimal dust leakage. Therefore, Material conveying fan In the course of China's industrial development, more and more enterprises have adopted it, among which airflow conveying systems are widely used.
Material conveying fan With a reasonable and durable structure, it is stable, reliable, highly efficient, highly adaptable to various working conditions, low-noise, and easy to maintain. It is an indispensable specialized equipment for wood, bamboo, furniture, plywood, and particleboard factories.
The principle of pneumatic conveying systems
Using the dynamic and static pressures of air or other gases, material particles are suspended in an airflow and introduced into the diffusion chamber of the hopper pump via regulating valves, movable ducts, and nozzles. Once the powdered material enters the high-speed airflow between the nozzle and the diffuser, it immediately disperses.
Pneumatic conveying systems have the following advantages:
1) The material conveying fan has high production efficiency.
2) Fewer devices, simple structure, small footprint, and easy to manage.
3) Highly automated;
4) Large scope of local labor and transportation;
5) Easy to handle and process, reducing material loss. Material conveying fan
6) Conducive to environmental protection and sanitation.
7) During transportation, processes such as mixing, pulverizing, grading, drying, cooling, and dust removal can be carried out.
8) Pneumatic conveying has low power consumption, which is half that of mechanical transportation. Material conveying fan.
9) Long transportation distance.
Classification of Pneumatic Conveying Systems
Pneumatic conveying systems can be classified according to many different criteria. Since pneumatic conveying system types vary significantly, their flow characteristics also differ greatly, and general flow laws cannot be applied universally across these systems. Based on the type of material being conveyed, pneumatic conveying can be divided into four major categories: tubular pneumatic conveying, dilute-phase pneumatic conveying, dense-phase dynamic-pressure pneumatic conveying, and dense-phase static-pressure pneumatic conveying.

Tube-type pneumatic conveying systems can be categorized into wheel-driven buckets and wheel-less driven buckets, depending on the type of loading bucket used. During transportation, the material is first loaded into a conveying tube, which is then propelled through the pipeline by means of high-speed gliding via static air pressure. This system is suitable for components that are not easily suspended and cannot be inserted or removed manually, making its application range relatively narrow.
Dilute-phase pneumatic conveying is a traditional method, and the technology for dilute-phase pneumatic conveying has become highly mature. It is also known as dilute-phase dynamic-pressure conveying, because material transport relies on the kinetic energy generated by high-speed air flow. This method is generally suitable for short-distance transportation of materials that are dry, easily fluidized, and characterized by small particle size and low mass.
