Keep two concepts in mind when considering the use of pneumatic conveying. First, the system pressure decreases along the length of the conveying pipe. This means that the specific volume of the gas increases as does its velocity. These factors limit the conveyance length. Second, there is a minimum velocity needed to carry the solids.
Pneumatic Conveying Methods. Utilizing air streams, either under pressure or in a vacuum, moves the materials. Three primary categories of pneumatic conveying methods exist: dilute phase, dense phase, and air conveying. These methods function based on specific velocities, pressures, and air-to-product ratios within the system.
Effective pneumatic conveying design requires careful attention to various factors: #### 1. Material Characteristics: Particle size and shape: This significantly impacts airflow requirements and potential for system blockages. Density and flowability: These determine the conveying velocity and pressure needed.
My article "Theory and Design of Dilute Phase Pneumatic Conveying Systems" was published this month in Powder Handling and Processing magazine. This article gives an easy to use Excel-based calculation method for designing new dilute phase pneumatic conveying systems or for improving the performance of existing conveying systems. Regards,

The document provides input parameters and calculations for designing a conveyor system. It includes: 1) Summaries of horizontal and vertical lengths, bends, diverting valves, and particle size for the conveyor system.
Common Applications of Pneumatic Conveying with ANFDs. As described above, a DDPS Nutsche Filter-Dryer allows multiple processing steps to be completed within the confines of a single vessel, thus avoiding potential exposure of the product to the environment or personnel during multiple transfer operations that would otherwise be required. This ...
Introduction. In solids processing systems, it is commonly required to transport solids from one location to another. Solids can be transported via various means, including (1) pneumatic conveying, in which solids are transported in a pipe or channel by gas flow through blowing or suction; (2) gravity chutes, where solids transport downward by gravitational force; (3) air …
Dense-phase pneumatic conveying relies on transferring materials at much lower velocities than normally experienced with screw pump conveying technology. The reason is that the Macawber conveying process does not depend on complete fluidisation of the cement and complete mixing of the cement with the conveying air.
What is Pneumatic Conveying? Pneumatic Conveying is a cost- and energy-efficient method of transporting dry bulk materials such as powders and granules from one place to another.. A typical example of a pneumatic conveying system that we engineer and manufacture involves conveying a material (such as polymer, lime, soda ash, plastic pellets/powder, dry milk etc.) …
Pneu-Con's pneumatic conveying systems and components are designed and manufactured to last. We routinely service systems and equipment for returning customers that we manufactured 25-30 years ago. Most of the time, this service is done to retrofit, adapt or modernize older dry material conveying systems to meet new customer needs. browse our parts
A pneumatic conveying system typically requires far more horsepower to operate than an equivalently sized mechanical conveying system. The reason is that changing the air pressure to achieve pneumatic conveying consumes a large amount of power and is inherently less efficient than a mechanical conveying system's mechanical transfer. In fact ...

Dense Phase Pneumatic Conveying. For conveying fragile or sheer sensitive products, a dense phase system is the better choice. These systems are designed to operate at low velocities to minimize product breakage and sheering. Dense phase uses a pulse of product pushed by a pulse of air, then another pulse of product followed by a pulse of air.
Pneumatic conveyors work best with fine, fluidizable, dry powders which can easily "fly" through the conveying line. There is a long list of different powders that can be conveyed with pneumatic conveying, including flour, cement powder, carbon black, sugar, plastic pellets, small food particles, tablets, sands, metal powders, and many more.

Why use pneumatic conveying to move bulk solids? With the appropriate choice of system, material can be transported with minimal degradation Little or no exposure of the product to the environment Can transport relatively long distances (several thousand feet) Excellent for multiple sources and multiple destinations Ability to transport material which might be air, moisture, etc. …
