Air-supplied hoist

a.Rationale：

The air-fed elevator employs the push effect of high-pressure airflow to elevate the material to a specified height through the conveying pipe. The high-speed airflow passes through the nozzle to create a negative pressure area, which draws the material in and conveys it upward along the pipeline.

b.Categorization：

Air supply type elevators can be classified into two main categories: positive pressure and negative pressure. The former refers to an airflow method that pushes the air through the system, while the latter pulls the air through.

In terms of application, these elevators can be further divided into three types: grain elevator, powder elevator and granule elevator.

c.Role：

The air-fed elevator is a highly versatile piece of machinery, used for the conveying and lifting of granular, powdery and small lumpy materials. It is a popular choice in a number of industries, including grain processing, chemical and pharmaceutical, due to a number of key advantages. These include a fast lifting speed, no damage to the materials being lifted, and low energy consumption.
