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.
Dust is a collection of particles in the atmosphere that can consist of anything from soil to pollen to skin cells. In terms of bulk material handling operations, dust mainly refers to tiny fragments of the very materials being transported or transferred. After dust is formed, it causes more wear on equipment components such as bearings, and can create a grinding effect for increased abrasion. It also leads to an increased risk of fire, higher maintenance costs and decreased visibility for workers.
Titanium dioxide is a naturally occurring oxide of titanium that is commonly sourced from minerals such as anatase, ilmenite, brookite and rutile. Known by the molecular formula TiO2, it is formed when two oxygen molecules attach to one titanium molecule during the process of oxidation. Although it occurs naturally in an impure form, the industrial demand for pure titanium dioxide necessitates its manufacture through processing.
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.
Canada's oil sand deposits contain the world’s second largest oil resource, after Saudi Arabia. Surface mining can extract around 20% of the oil and currently covers about 342 square miles in the province of Alberta, roughly two-thirds the size of the city of Los Angeles. In their natural state, oil sands are loose particles that are a combination of clay, sand and water saturated with bitumen. Processing of this material fundamentally separates oil-bearing bitumen from the sand itself, and can also be referred to as bituminous sands.
Calcination is loosely defined as thermal processing done at elevated temperatures to change the properties of a given material. Calcining is often applied to ores and other solid materials to bring about a thermal decomposition, phase transition or removal of a volatile fraction. The calcination process normally takes place at temperatures below the melting point of the material being calcined.
The search is on for alternative sources of fuel. Social and political instability in the vicinity of major oil producing regions has led to rising prices, which hampers a slow economic recovery as consumers are forced to spend more of their limited incomes on gasoline. Major spills in waterways and in the Gulf of Mexico provide dramatic reminders of the risks inherent in oil exploration and production, and their effect on the environment.
Sand is one of many bulk mateials, and is a vital component in a variety of industrial applications. From simple molding to its use as a crucial ingredient in concrete and asphalt, much of the world we know would be substantially different without sand. A problem that those in the industry face, however, is that part of the process for treating sand for some applications heats it up considerably, requiring it to be cooled before further use.
FOR IMMEDIATE RELEASE: Pittsburgh, PA – Heyl & Patterson Inc., a world leader in thermal processing and bulk materials handling equipment, today announced its relocation to a new base of operations at 400 Lydia Street in Carnegie, PA, in a move to accommodate growth.
Since 1875, the United States has been one of the world's main steel producers. Steel has been an important factor in the American economy for over 100 years, providing jobs to many generations of American families, and it continues to be a booming industry today. Production of steel takes place in two different ways. One method uses integrated smelting involving a blast furnace, followed by a basic oxygen furnace, and the other involves an electric arc furnace.
