Aerogran™
Eagle Engineering's Aerogran™ is an advanced granular color dispensing system purpose-built for the concrete masonry unit (CMU) industry. Vibratory technology replaces traditional screw-based feeders for cleaner, more reliable operation with zero contamination risk.
Granular color handling in CMU production often leads to contamination, inconsistent dosing, and ongoing maintenance from screw-based systems. Aerogran™ was built to eliminate those issues with a cleaner, more reliable approach.
INSIGHTS
Aerogran™ Granular Dispensing
Read article →Why CMU Producers Use Aerogran™
Each batch individually weighed, not estimated, for run-to-run color consistency across 125 to 1,400 BBL production
Complete cleanout after every batch eliminates cross-contamination between color changes
Stores up to 400 color formulas with optional expansion. No manual re-entry per job or per operator.
Vibratory feeders replace screw augers: no wear parts in the feed path, no pigment carryover, lower maintenance burden
Transfers to mixers up to 80 ft. away and 40 ft. above for flexible installation in existing plant configurations

Aerogran™ in the Field
System Highlights
Vibratory Feeders
No screws: vibratory technology eliminates the wear and contamination issues common to auger-based systems, resulting in cleaner operation and lower maintenance costs.
Coarse & Fine Metering
Two-stage metering delivers both bulk and precision dosing in a single system, ensuring maximum accuracy across the full range of granular color pigments.
Pneumatic Conveying
Enclosed pneumatic transfer moves granular pigment from dispenser to mixer cleanly and efficiently, dust-controlled from source to destination.
Super Sack Loading
Direct loading from 1-ton super sacks (FIBC), eliminating manual scooping and minimizing operator exposure and material waste throughout the production shift.
Case Studies

CMU Producer Cuts Color Rejection Rate After Switching from Screw-Based System to Aerogran™
A midwest concrete block manufacturer was experiencing batch-to-batch color inconsistency and escalating maintenance costs from an aging auger-based color system. After installing the Aerogran™, rejection rates dropped and production uptime improved across all four color lines.

How One Block Plant Reduced Color System Maintenance by Replacing Auger Feeders with Vibratory Technology
Cross-contamination between pigment colors was creating rework and waste at a high-volume CMU facility running multiple colors per shift. The Aerogran™'s enclosed pneumatic transfer and vibratory feed mechanism eliminated the contamination path and reduced weekly maintenance time significantly.
