In most pneumatic conveying applications, closed-bottom rotary valves, such as that shown in Figure 4, are more commonly used because they provide a better air seal between the rotor edges and the valve body. For feeding coarse particles such as plastic pellets, drop-through rotary valves are provided with a well-configured inlet plow …
The flowing conveying air transmits a propulsion force on the bulk material and thus conveys it through the conveying line. The pneumatic conveying always requires a pressure difference between the beginning and the end of the pipeline. To overcome this pressure difference, conveying blowers or compressors are used.

Closed loop pneumatic conveying systems; for materials that are sensitive to oxygen or moisture, nitrogen is generally used in these applications. The proper selection of blowers plays a crucial role in overall performance of pneumatic conveying systems. Physical and chemical properties of bulk material, transfer capacity, conveying distance ...
One of the two outlets is always completely closed by a tightly-sealed slide plate. The slide plate is activated by a shaft and a lever and moves on an exchangeable wear protection plate. Switch-over is possible only when conveying operations have been stopped. ... The SK V2 valve can be used in dilute, two-phase or dense-phase pneumatic ...
Closed loop pneumatic conveying is a specific application of pneumatic conveying for which the gas is recirculated. It is used in special applications where there is an interest …
Pneumatic conveying provides a cost-effective way to handle and transfer powdered and bulk granular materials easily with very little loss. It is suitable for a range of process industries such as; Food and Beverage, Pet Food, Chemicals and Detergents, Renewables and Specialist Materials. What are the categories of pneumatic conveying?
density" we mean that a 2 inch particle of a polymer resin can be moved via pneumatic conveying, but a 2 inch lead ball would not. Types of Pneumatic Conveying There are several methods of transporting materials using pneumatic conveying. In general, they seem to fall into three main categories: dilute phase, dense phase, and air conveying. 1.
