Phoenix Cement Company
The Phoenix Cement Company, headquartered in Phoenix, operates a cement plant in Clarkdale in the U.S. state of Arizona. Built in 1959 by the American Cement Company to make cement for construction of the Glen Canyon Dam on the Colorado River, the Clarkdale plant produces Portland cement, fly ash, and gypsum for a regional market. The first load of cement for the dam left Clarkdale by truck in October 1959, and shipments continued for nearly five years. North of Flagstaff, the trucks in the early years traveled on an unpaved road to Page, where the dam was being built. A truck loaded with cement left the Clarkdale plant every 15 minutes until the dam was finished in July 1964. Plans called for the plant to close after the dam was completed, but other projects materialized. Instead of decommissioning the plant, the owners expanded it by one-third in 1961, and it has since become the main source of cement for northern Arizona and Phoenix. In 2002, the company added a new kiln ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Private Company
A privately held company (or simply a private company) is a company whose shares and related rights or obligations are not offered for public subscription or publicly negotiated in the respective listed markets, but rather the company's stock is offered, owned, traded, exchanged privately, or over-the-counter. In the case of a closed corporation, there are a relatively small number of shareholders or company members. Related terms are closely-held corporation, unquoted company, and unlisted company. Though less visible than their publicly traded counterparts, private companies have major importance in the world's economy. In 2008, the 441 largest private companies in the United States accounted for ($1.8 trillion) in revenues and employed 6.2 million people, according to ''Forbes''. In 2005, using a substantially smaller pool size (22.7%) for comparison, the 339 companies on '' Forbes'' survey of closely held U.S. businesses sold a trillion dollars' worth of goods and services ...

Gypsum
Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula . It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard or sidewalk chalk, and drywall. Alabaster, a fine-grained white or lightly tinted variety of gypsum, has been used for sculpture by many cultures including Ancient Egypt, Mesopotamia, Ancient Rome, the Byzantine Empire, and the Nottingham alabasters of Medieval England. Gypsum also crystallizes as translucent crystals of selenite. It forms as an evaporite mineral and as a hydration product of anhydrite. The Mohs scale of mineral hardness defines gypsum as hardness value 2 based on scratch hardness comparison. Etymology and history The word '' gypsum'' is derived from the Greek word (), "plaster". Because the quarries of the Montmartre district of Paris have long furnished burnt gypsum ( calcined gypsum) used for various purposes, this dehydrated gyp ...

Cement Companies Of The United States
A cement is a binder (material), binder, a chemical substance used for construction that solidification, sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel (construction aggregate, aggregate) together. Cement mixed with fine aggregate produces mortar (masonry), mortar for masonry, or with sand and gravel, produces concrete. Concrete is the most widely used material in existence and is behind only water as the planet's most-consumed resource. Cements used in construction are usually inorganic, often lime (material), lime or calcium silicate based, which can be characterized as hydraulic or the less common non-hydraulic, depending on the ability of the cement to set in the presence of water (see Lime mortar#Hydraulic and non-hydraulic lime, hydraulic and non-hydraulic lime plaster). Hydraulic cements (e.g., Portland cement) set and become adhesive through a chemical reaction between the dry i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salt River Pima-Maricopa Indian Community
Salt is a mineral composed primarily of sodium chloride (NaCl), a chemical compound belonging to the larger class of salts; salt in the form of a natural crystalline mineral is known as rock salt or halite. Salt is present in vast quantities in seawater. The open ocean has about of solids per liter of sea water, a salinity of 3.5%. Salt is essential for life in general, and saltiness is one of the basic human tastes. Salt is one of the oldest and most ubiquitous food seasonings, and is known to uniformly improve the taste perception of food, including otherwise unpalatable food. Salting, brining, and pickling are also ancient and important methods of food preservation. Some of the earliest evidence of salt processing dates to around 6,000 BC, when people living in the area of present-day Romania boiled spring water to extract salts; a salt-works in China dates to approximately the same period. Salt was also prized by the ancient Hebrews, Greeks, Romans, Byzantines, H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Preheater
An air preheater is any device designed to heat air before another process (for example, combustion in a boiler With the primary objective of increasing the thermal efficiency of the process. They may be used alone or to replace a recuperative heat system or to replace a steam coil. In particular, this article describes the combustion air preheaters used in large boilers found in thermal power stations producing electric power from e.g. fossil fuels, biomass or waste. (See Chapter 8 by Z.H. Lin) For instance, as the Ljungström air preheater has been attributed worldwide fuel savings estimated to 4,960,000,000 tons of oil, "few inventions have been as successful in saving fuel as the Ljungström Air Preheater", marked as the 44th International Historic Mechanical Engineering Landmark by the American Society of Mechanical Engineers. The purpose of the air preheater is to recover the heat from the boiler flue gas which increases the thermal efficiency of the boiler by ...

Kiln
A kiln is a thermally insulated chamber, a type of oven, that produces temperatures sufficient to complete some process, such as hardening, drying, or chemical changes. Kilns have been used for millennia to turn objects made from clay into pottery, tiles and bricks. Various industries use rotary kilns for pyroprocessing—to calcinate ores, to calcinate limestone to lime for cement, and to transform many other materials. Pronunciation and etymology According to the Oxford English Dictionary, kiln was derived from the words cyline, cylene, cyln(e) in Old English, in turn derived from Latin ''culina'' ("kitchen"). In Middle English the word is attested as kulne, kyllne, kilne, kiln, kylle, kyll, kil, kill, keele, kiele. For over 600 years, the final "n" in kiln was silent. It wasn't until the late 20th century where the "n" began to be pronounced. This is due to a phenomenon known as spelling pronunciation, where the pronunciation of a word is surmised from its spell ...

Page, Arizona
Page is a city in Coconino County, Arizona, United States, near the Glen Canyon Dam and Lake Powell. As of the 2010 census, the population of the city was 7,247. History Unlike other cities in the area, Page was founded in 1957 as a housing community for workers and their families during the construction of nearby Glen Canyon Dam on the Colorado River. Its site was obtained in a land exchange with the Navajo Nation. The city is perched atop Manson Mesa at an elevation of above sea level and above Lake Powell. The city was originally called Government Camp, but was later named for John C. Page, commissioner of the Bureau of Reclamation, 1936–1943. After the dam was completed in 1966, Page officially incorporated as a town on March 1, 1975. The city grew steadily to today's population over 7,000. Because of the new roads and bridge built for use during construction, it has become the gateway to the Glen Canyon National Recreation Area and Lake Powell, attracting more tha ...

Fly Ash
Fly ash, flue ash, coal ash, or pulverised fuel ash (in the UK) plurale tantum: coal combustion residuals (CCRs)is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coal-fired boilers together with the flue gases. Ash that falls to the bottom of the boiler's combustion chamber (commonly called a firebox) is called bottom ash. In modern coal-fired power plants, fly ash is generally captured by electrostatic precipitators or other particle filtration equipment before the flue gases reach the chimneys. Together with bottom ash removed from the bottom of the boiler, it is known as coal ash. Depending upon the source and composition of the coal being burned, the components of fly ash vary considerably, but all fly ash includes substantial amounts of silicon dioxide (SiO2) (both amorphous and crystalline), aluminium oxide (Al2O3) and calcium oxide (CaO), the main mineral compounds in coal-bearing rock strata. ...

Clarkdale, Arizona
Clarkdale (Yavapai: Saupkasuiva) is a town in Yavapai County, Arizona, United States. The Verde River flows through the town as does Bitter Creek, an intermittent tributary of the river. According to the 2010 census, the population of the town was 4,097. Clarkdale, formerly a mining town, is now largely a retirement community and arts community. History Clarkdale was founded in 1912 as a company smelter town by William A. Clark, for his copper mine in nearby Jerome. Clarkdale was one of the most modern mining towns in the world, including telephone, telegraph, electrical, sewer and spring water services, and was an early example of a planned community. The Clark Mansion, a local landmark, was built in the late 1920s by William Clark III, Clark's grandson and heir to the United Verde Copper Company. The structure, east of town across the Verde River near Pecks Lake, was destroyed in 2010 by a fire of "suspicious" origin. The town center and business district were built in Sp ...
