The mining and minerals processing industry is a proving ground for industrial equipment, demanding solutions that can endure the harshest conditions without faltering. When a major processor embarked on building a new Powder Processing facility, they faced a formidable challenge: handling diatomaceous earth (DE) . This fine, powdery, and highly abrasive material required a material handling solution that was not merely robust but a strategic, long-term investment for operati

1. The Challenge: Abrasive Fuel and Equipment Failure In 2007, a 305 Megawatt Circulating Fluid Bed Boiler (CFB) plant near College Station, Texas, faced a significant operational challenge. The plant's primary fuel, lignite, a brown coal and the lowest-ranking type of coal, was causing continuous problems for its material handling equipment. Lignite, a material that is abrasive, sticky, and flammable, was being metered into the boiler via a gravimetric feeder. A critical com

A Case Study by Delta Ducon 1. Executive Summary: The Challenge of Abrasive Marble Dust In the demanding world of mineral processing, the phrase "rotary valve wear" is often synonymous with costly downtime, frequent maintenance, and frustratingly short equipment life. A prominent marble processing plant in the southern United States faced this exact predicament. Their process, which involved pneumatically conveying highly abrasive marble dust, was hampered by the rapid failur

Introduction: The Painful Problem of Passing Stones In the world of industrial manufacturing, a seemingly simple problem can quickly become a costly and frustrating ordeal. For National Gypsum's Burlington, New Jersey plant, the challenge was to efficiently discharge a mix of gypsum rocks and fine powder from their 300-ton capacity storage silos onto a conveyor belt. The material—composed of brittle, chalky gypsum rocks up to 2 inches in diameter and extremely fine powder—pre

The Challenge:   In early 2024, a prominent Mid-Western USA Pulp & Paper Mill faced persistent operational challenges with its existing...
