Repositioning railroad cars in a rail-switching operation has always been a formidable task. Prior to the development of specialized railcar movers, full-size locomotives were often employed to move the cars across relatively short distances. Locomotives are very expensive and overpowered for the situation. They often require a special rail yard design to allow them to move cars around or out of the way of connecting rail carriers, while older locomotives used specifically for this purpose may not have readily available parts.Read More

Heyl & Patterson Inc., a world leader in bulk material handling and thermal processing systems, will present “Fluid Bed and Rotary Dryers for Frac Sand” at the 2015 Oilfield Minerals & Markets Forum on Thursday, May 28 at 4:30 PM CST at The Houstonian Hotel in Houston, TX. The conference covers global shale gas development, utilization and outlook, and will be held on May 27-29.Read More
An all-too-painful truth is that bulk material handling equipment breaks down over time, and whenever it occurs, it's almost always costly. The most common problems that lead to breakdowns are actually quite preventable. They include improper maintenance, overrunning a machine's capability, not replacing worn parts, poor electrical connections, and even operation by untrained personnel or not consulting the operator manual. Almost all mean that someone has ignored the warning signs of an impending stoppage. These problems account for most of the breakdowns seen in the field, and all are avoidable by taking some simple precautions.Read More
Biomass co-firing is the burning of fossil fuels in coal-fired power plants in conjunction with forestry and agriculture residues, animal manure, wood wastes, such as sawdust or bark from the timber industry, waste wood and dedicated energy crops. Co-firing increases the amount of renewable biomass in the global energy mix and also reduces greenhouse gas emissions. The technologies include biomass that is jointly milled with coal and fed into the same boiler, biomass that is converted into a fuel gas and then burned with coal in the same boiler, and biomass in a separate boiler that supplies steam to a coal cycle.Read More
Electricity has been generated at power stations since 1882, and the first such plants ran on water or coal. Over 130 years later, the modern world mainly relies on coal, nuclear, natural gas, petroleum, hydroelectric and biomass, with a small amount from wind, solar, tidal and geothermal sources. The process of powering by electricity is known as electrification, and like these methods of power generation, it is usually associated with a change in a power source from one form to another.
Hydraulic fracturing, also called "fracking" or "fracing," permits access to vast amounts of natural gas that had previously been unreachable. A well is first drilled into a rock formation, and a high-pressure fluid containing a propping agent, or proppant, is then injected into the well. This mixture typically consists of water, sand and a proprietary blend of chemicals. Once injected into the well, the proppant prevents the fracture from closing, which allows the gas to flow freely.
Prior to the Civil War, cities in the Ohio and Mississippi Valleys such as Pittsburgh and St. Louis were wholly dependent upon steamboats as a means of transporting bulk materials. Even after barges entered service, they were unloaded by hand because unloading machines had not yet been developed. Productivity improved along with technology, and new processes were developed for machinery production and mechanization.
Heyl & Patterson introduced the first-ever conference designed for users of railcar dumping systems in 1984. Thirty years later, the conference continues to bring users together for industry best practices, product updates, training, roundtables and social networking. Attendees of the bi-annual Railcar Dumper User Group Conference have access to Heyl & Patterson engineers and technicians to discuss the most up-to-date techniques and processes for efficient operations.
According to software developer Symantec, organizations understand that “app culture” is not going away, and in order to avoid falling behind, they need to integrate themselves into that world. iPhone and Android operating systems have significantly changed how cellphones function, making them about productivity in addition to communication. Currently, 71% of companies are either investigating or are actively deploying their own mobile applications.
A powder is a bulk solid material composed of a large number of very fine, dry particles that flow freely when held at an angle. These substances are a type of granular material that have finer grain sizes, so they have a greater tendency to clump when flowing, as opposed to coarser materials that do not form clumps except when wet. Due to their small particle size, powders are more cohesive and more easily suspended in gas.
