In 1966 approximately 125 million tons of raw materials exclusive of fuel air water and power were consumed to produce almost 74 million tons of portland cement in the United States that is about 3 400 pounds of raw material per ton of finished cement produced To present the figure in another way a single plant producing 600 000 tons of cement a year would consume about 1 000 000 tons
Monitor raw material feed to crushers mills screens preparation plants and coal fired power plants to help ensure precise feeding of process materials and maintain product quality Thermo Scientific Ramsey conveyor belt scales provide vital information for the effective management and efficient operation of cement raw material
The cement raw materials is formed with calcareous materials clayey materials and slight corrective material in appropriate proportion and grinded into certain fineness The raw material production of cement plant can be classified into four steps crushing grinding mixing and homogenizing
Cement Cement Extraction and processing Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones slates and some shales with the aid of blasting when necessary Some deposits are mined by underground methods Softer rocks such as chalk and clay can be dug directly by excavators
The capital intensive cement industry needs to secure valuable deposits over the long term Close geographical links between cement production and mining sites is also extremely important Short routes for supply of raw materials take pressure off of traffic volumes and reduce transport related emission of pollutants
Cement Bulk Material Control and Handling Equipment Cement raw materials are crushed and stocked into a special pile for blending to reduce the variability The material is then transported to the raw mix proportioning area lower productions costs and create safer cleaner cement production
We use alternative raw materials for the production of clinker which is the most important intermediate product in the manufacture of cement In this way we reduce the amount of CO 2 intensive clinker in the final product The increased use of alternative raw materials in cement production
