polysilicon is an important semiconductor material, and its basic physical and chemical properties are as follows: it has a crystal structure, formed by silicon atoms connected by covalent bonds, has a melting point of 1414°C, high hardness, and good electrical conductivity and thermal stability. Polysilicon is relatively stable in chemical reactions, not easily oxidized or reduced, and is commonly used in the manufacturing of solar cells and semiconductor devices. The common transportation methods of polysilicon mainly include pipeline transportation, tank truck transportation, container transportation and bulk ship transportation. When choosing a polysilicon conveying method, the material characteristics, transportation needs, and whether there are other transportation needs should be taken into account. Pipeline transportation is suitable for long-distance and large-volume transportation, tank truck transportation is suitable for short- and medium-distance and large-volume transportation, container transportation is suitable for international transportation, and bulk carrier transportation is suitable for long-distance and large-volume sea transportation.

1. Common conveying methods

The common conveying methods of

polysilicon are mainly divided into mechanical conveying and pneumatic conveying. Mechanical conveying relies on the movement of mechanical components, which is a traditional basic method, suitable for short distances, low height, and small flow scenarios, including screw conveyors, bucket elevators, belt conveyors, and scraper conveyors, each with its own unique principles and characteristics. The screw conveyor realizes the continuous transportation of materials through the rotation of the spiral blades; The bucket elevator lifts the material vertically through the cyclic movement of the lifting bucket; the belt conveyor uses the continuous movement of the belt for horizontal or inclined conveying; The scraper conveyor realizes the conveying of materials through the push of the scraper. Pneumatic conveying is the use of airflow energy to transport materials in closed pipelines, which is the core technology of material processing, warehousing, and packaging, and its advantage is that it can adapt to different material characteristics, improve transportation efficiency and reduce dust pollution.

2. Can polysilicon be conveyed by pneumatic force?

polysilicon is suitable for pneumatic conveying, because of its fine particles, small density, good fluidity and no obvious adhesion, it meets the requirements of powder material conveying and has excellent quality of closed conveying. Pneumatic conveying uses compressed air or vacuum as the power to carry the material through the airflow in the closed pipeline, and uses the separator to achieve gas-solid separation. According to the conveying pressure and power form, pneumatic conveying can be divided into negative pressure suction type, positive pressure pressure pressure conveying type and mixed type, and according to the gas-solid mixing concentration, the dilute phase conveying method is usually used.
