The cement industry recognizes its responsibility to manage the environmental impact, associated with the manufacturing of its product. Mainly, there are two types of cement production process; such as wet process and dry process. The preparation of cement includes mining, crushing, and grinding of raw materials, calcining the materials in 1408

The grinding process impacts the cement manufacture in at least two ways. First, an increase of the fineness and homogeneity of the raw mix accelerates the clinkering reactions, leading to less variability of the clinker due to the enhanced stability of the kiln and better energy efficiency in producing a clinker of better consistency.
Cement types. With concerns over environmental impacts of cement manufacture, decreasing the clinker content in concrete requires increasing the utilization of supplementary cementitious materials like GBFS and pozzolans. Shown below, are cement types in common use with varying degrees of clinker component.
plant is now a cement grinding facility and fly ash distribution location. The Bellingham plant receives all of its clinker from the Lehigh plant in Delta, British Columbia. Raw materials for cement production are received by rail, truck and barge into the Port of Bellingham. Water and rail access helps mitigate our environmental impacts

Portland cement and the environment. Portland cement is manufactured by heating limestone or chalk with clay in a rotary kiln to a high temperature (about 1450°C) to produce hard nodules of clinker that are then ground with a little gypsum in a ball mill. The firing process consumes significant quantities of fuel, usually coal or petroleum coke.
Environmental Impact of Cement. Cement is a fine gray powder used in the production of concrete and mortar. A total of 12 billion tons of concrete, 1 or approximately 3 billion tons of cement, 2 are used around the world each year. With each person consuming about 3 tons of cement annually, it is the second most used material on Earth after water. 3 Cement is an …
New Market Pressures . The cement industry is facing new challenges in the form of rising competition, ever-increasing raw material and energy prices, and the need to comply with stricter environmental protection policies – challenges that can no longer be faced with the traditional tools used by the industry prior to 2014.
Environmental impacts of the milling process is minimal other than the dust that is produced by the mill grinding the clinker into powder form. The ball mill would also produce exhaust fume emissions similar to all other machinery that would pollute the atmosphere and as a result, cause some production of greenhouse gases.
