Delta Ducon's Power Group is heading to Birmingham, Alabama for the 2026 Southern Company Tech Conference, bringing over 100 years of power industry experience to the exhibit floor. Attendees can see live demos of the company's pneumatic ash handling, fuel transfer, and environmental compliance systems, and talk shop with the team about their toughest material handling challenges.

Not every pneumatic conveying vendor is built for severe-duty, high-abrasive materials — here's the checklist that separates true industry leaders from the rest.

Screw pumps and FK pumps are wearing out faster and costing more to maintain — here's how dilute, semi-dense, and dense phase conveying compare as replacement paths.

Cement, steel, mining, power, and glass manufacturers all face the same problem: abrasive dry bulk materials wear out pneumatic conveying lines fast. Here's how the challenge shows up across industries — and how it gets solved.

Tightening NFPA and EPA standards are pushing cement, lime, and gypsum plants to replace open material transfer with fully enclosed pneumatic conveying.

Pulverized bio-carbon and lime injection is putting new stress on convey lines. Learn how dilute, dense, and semi-dense (slug flow) pneumatic conveying compare for EAF injection — and how the right choice depends on your material and site.

A rotary valve rated for "high temperature" service means very little on a spec sheet. What matters is what happens to that valve on the worst day of its operating life — the process upset, the boiler trip, the moment temperatures spike well past the number printed in the catalog. Most rotary valves fail exactly then, at the point they're needed most, because they were built to tolerate elevated temperature rather than engineered to survive it. This article covers what actual

Since 1921, Delta Ducon has engineered dilute, semi-dense, and dense phase conveying solutions for severe-duty applications. Explore a century of innovation, from the 1958 B feeder to modern screw pump replacement systems.

Always great to see our equipment playing a role in cleaning up old mine sites right here in Pennsylvania. 🌲 The Delta Ducon Power Group engineering team has officially wrapped up shipments for a new 20 TPH (Tons Per Hour) Crushed Limestone Optimization Project at a 110 MW power plant in Western, PA. The facility's installation contractors are now on-site putting everything together, with the system slated for an official start-up later this summer. To ensure long-term relia

Pneumatic conveying line wear from slag

The industrial shift toward net-zero fuels (biomass, RDF) alters flue gas compositions, often increasing acid gas volatility ($HCl$, $SO_x$).

Reclamation: Delta Ducon Supplies 20 TPH Limestone System It is always rewarding to see Delta Ducon equipment playing a direct role in environmental remediation and cleaning up legacy mine sites right here in Pennsylvania. We just wrapped up shipments for a 20 TPH (Tons Per Hour) Crushed Limestone Optimization Project at a 110 MW power plant in Western, Pennsylvania. The facility's installation contractors are officially on-site assembling the machinery, and the pneumatic con

Over the past few weeks, we’ve stripped pneumatic conveying down to its core fundamentals. We analyzed the unique physics of Knowing Your Material, mapped out the fluid dynamics required for Proper Pipe Routing, and discussed the operational discipline needed for Maintenance and Installation. But here is the hard truth that many plant operations and engineering teams learn the painful way: You can design the most flawless, mathematically perfect pipe route in the world, but i

Every maintenance manager and plant operations director knows the feeling. You’ve fine-tuned your production schedule, your team is hitting their targets, and then—click, grind, stop. A critical elbow has blown out, a rotary valve has seized, or a diverter valve has jammed up, bringing your entire throughput grinding to a halt. In heavy industry, we often joke about "gremlins" in the system. But the reality isn't a mystery; it’s just physics. When you are conveying abrasive m

A Technical Evaluation of Modernizing Cement and Mineral Conveyance Executive Summary For decades, the screw pump—most notably the industry-standard Fuller-Kinyon (FK) style—has been the backbone of dry bulk material transport in cement and mineral processing. While these systems were revolutionary for their time, the requirements of the modern industrial landscape have outpaced the mechanical capabilities of legacy screw pump technology. This paper explores the inherent pitf

We are proud to share that Delta Ducon’s very own Matt DelPizzo, recently had the honor of presenting a technical poster at the 2026 IEEE-IAS/PCA Cement Conference in Ft. Lauderdale, FL. The presentation focused on a critical issue facing many cement and heavy industrial facilities: mitigating extreme erosive wear during the pneumatic transport of petroleum coke. The Challenge: When Standard Solutions Fail The poster highlights a recent case study involving a major U.S. cemen

In the demanding world of heavy industry, efficiency is not just a goal - it is a necessity. When handling bulk materials, every component of the system must perform flawlessly to maintain productivity and reduce downtime. One critical component that often determines the success of pneumatic conveying systems is the rotary valve. Improving rotary valves efficiency can lead to significant gains in operational reliability and cost savings. Today, I want to share insights on how
