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

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

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

In the high-stakes world of abrasive material handling, downtime is more than just an inconvenience—it is a significant drain on profitability. For plants handling cement, minerals, and ores, the relentless wear on equipment leads to frequent part replacements and energy loss. To combat this, Delta Ducon has engineered a "Triple Threat" of hardware designed to outlast the competition: the Extreme Duty Rotary Valve , PERMA/flo Abrasion-Resistant Fittings , and the KG Diverter

The global cement industry is currently undergoing its most significant transformation in a century. As producers face increasing pressure to reduce carbon footprints while maintaining high-volume throughput, the efficiency of material handling systems has become the primary driver of profitability. Delta Ducon has positioned itself at the forefront of this evolution, providing engineered solutions that bridge the gap between traditional clinker production and the burgeoning

In the demanding world of dry bulk material handling, the margin for error is non-existent. Survival for industrial plants depends on a combination of legacy experience and cutting-edge mechanical innovation. Delta Ducon , a cornerstone of the North American industry for over 100 years, has recently redefined the market through a strategic partnership with Clyde Pneumatics , a global leader with 50 years of expertise. By merging Delta Ducon’s century of "Extreme Duty" experti

In industrial sectors where materials behave like liquid sandpaper, the difference between a profitable operation and a maintenance nightmare lies in the specific engineering of the conveying system. For over 100 years, Delta Ducon has occupied the "Extreme Duty" niche, providing high-performance products for the mining, minerals, cement, and power industries. When standard industrial equipment fails in weeks, our systems are just getting started. Beyond Standard Handling: T

In my thirty years in bulk material handling, I’ve observed a consistent truth: the success of a critical mineral project—whether it’s Copper, Magnesium, or Phosphate—isn’t won at the extraction site; it’s won in the conveying infrastructure. When you are processing high-value, highly abrasive materials, your equipment doesn't just face "wear and tear"—it faces an aggressive environment that demands a century of engineering pedigree to survive. At Delta Ducon, we don’t just m

Fort Lauderdale, sun-drenched and teeming with energy, is about to become the epicenter of the cement industry's latest innovations. The 2026 IEEE-IAS ACA Cement Conference is just around the corner, and for anyone involved in navigating the challenges of material handling in this demanding environment, Delta Ducon, LLC in Hall A, Booth 606, is a destination you can't afford to miss. The cement industry, as we all know, is in a state of flux. While we strive for greater effic

Choosing the right pneumatic conveying system is more than a technical decision; it’s an operational strategy that impacts your plant's uptime, energy bills, and maintenance cycles. For engineers and plant managers, the debate often narrows down to two primary contenders: Dilute Phase and Dense Phase . While industry "common knowledge" often pigeonholes these systems into rigid categories—such as claiming that dilute phase can’t handle abrasives—the reality on the factory fl

In the world of pneumatic conveying, a rotary valve is often viewed as a simple "commodity" component. When a valve fails or a new system is being specified, the temptation to choose the lowest-bidder option is strong. On paper, a budget valve and a high-performance valve look similar—they both have a rotor, a housing, and a motor. However, the "sticker price" of a rotary valve is only the tip of the iceberg. In high-abrasive markets, the Total Cost of Ownership (TCO) for a

How Delta Ducon Solved a catastrophic Start-Up Failure and Saved a Multi-Million Dollar Process. In the high-stakes world of bulk material handling, equipment failure isn't just an inconvenience—it is a financial hemorrhage. This case study details how Delta Ducon intervened during a critical start-up failure at a major US based fly ash beneficiation plant. When a competitor’s standard rotary valve failed immediately due to the extreme abrasiveness of beneficiated ash, Delta
