Pneumatic Conveying Blower and Air Systems

Application Overview

What This Application Involves

Pneumatic conveying moves powders, pellets, granules, and bulk materials through pipe using either positive pressure or vacuum. Systems range from dilute-phase to dense-phase, and from short in-plant lines to long runs between silos and process equipment.

Compressed air, blower packages, and vacuum packages each have appropriate applications. Choosing between them is a project engineering decision driven by material properties, distance, rate, and system pressure.

Air Usage

Where Compressed Air Is Involved

Positive-pressure conveying air
Vacuum for pull-side conveying
Valve and diverter actuation
Silo aeration and fluidization
Bulk bag handling and dust collection support

System Design

Why Compressor-System Design Matters

●Material bulk density and flow behavior
●Conveying distance and elevation
●Required throughput
●Dilute-phase versus dense-phase strategy
●System pressure or vacuum profile

Symptoms

Problems an Inadequate System Can Cause

Pipe wear and material degradation

Conveying velocity that is too high can wear pipe and damage material. System design should match the material.

Line plugging and blockages

Undersized blowers or improper phase selection can cause plugging. Engineering review of the material and layout is needed.

Excessive energy use

Poorly sized systems can consume more power than needed. Right-sizing to actual demand should be part of the design.

These symptoms may be connected to the compressed-air supply and should be evaluated alongside the machine itself.

Equipment

Equipment That May Be Part of the Project

FAQ

Frequently Asked Questions

+Should we use compressed air or a blower?

It depends on the material, distance, and pressure. Long or high-rate conveying is often better matched to blower packages, while short high-pressure moves may use compressed air. This should be engineered against the material.

+What is the difference between dilute-phase and dense-phase conveying?

Dilute-phase uses higher velocity and lower loading; dense-phase uses lower velocity and higher loading. Each fits different materials and priorities.

+Can our existing blower support more capacity?

That should be reviewed against blower curve, motor, and system pressure requirements at the new rate.

+What information should we send?

Material description, distance, rate, current equipment, and any existing issues.
