The manufacturing starts with quarrying of limestone and shale. Holcim uses a Quarry Scheduling Optimization (QSO) program to carefully assess the proper areas to mine within a specific time period. Alternative Fuels and Raw Materials (AFR) By using waste materials as alternative fuel or raw materials, we are able to help industries and local

Holcim’s Ste. Genevieve cement plant is iconic as the most technologically advanced, as well as the largest, in the United States. One in five building projects in the U.S. contains Ste. Genevieve-produced cement because of the access our plant has to America’s river system, including the Mississippi River on its eastern border

Lime Component Limestone: Common forms of calcium carbonate used as raw material for cement manufacturing are limestone and chalk.Limestone is of predominantly fine grained crystalline structure, its hardness is between 1.8 to 3.0 of the Mohs scale of hardness and specific gravity 2. To 2.8. Limestone usually contains admixtures of clay substance or iron compounds, which influences its color

in Ada, Oklahoma. Holcim is proposing to increase the amount of raw material used in the manufacture of cement by 20,000 tons per year to meet customer demands. At their request, Holcim met with Region 6 and the Oklahoma Department of Environmental Quality (via telephone) in Region 6 offices on December 17, 2004, to discuss the project. In

Limestone a major raw material component of cement manufacturing is sourced from the Holcim Mining Development Coporation quarry and are transported to Holcim Davao cement plant’s crusher through dump trucks. The crusher is designed to have a capacity of 1,000 tons/hr. The crushed raw

The cement making process is energy and material intensive. Traditionally, fossil fuels and natural raw materials have been used to make clinker, the main ingredient in cement. To operate its business in a more environmentally, economically and socially beneficial way, Holcim is increasingly using non-traditional or “Alternative Fuels and Raw

2) Crusher. The crusher reduces rocks to a diameter of an average of 10cm. In the crusher, raw materials are mixed with mineral components. The exact proportions are controlled through an analyzer , which is installed on the transport line towards the pre-homogenization storage
