Sohag – LOESCHE is involved in the new construction of a large cement plant in Egypt with three vertical roller mills The end customer is the Egyptian Cement for Cement Projects Management SAE The planned new plant is located nearly 500 km south of Cairo in Sohag
Vincent explained that the cement industry almost exclusively uses indirect also known as storage firing systems with an air swept mill All air and material goes to a form of intermediate storage like a bag filter and from the bag filter it mechanically or pneumatically goes to a silo where it will be fed to the burners
In the cement production line producing 1 ton of Cement need grind at least 3 tons of materials including raw materials fuel clinker mixed materialsgypsumGrinding operation consumes about 60 of total power in cement plants raw material grinding more than 30 while coal mill used in cement plant consumes 3 cement grinding about 40
The cement mill grinds the clinker to a fine powder A small amount of gypsum a form of calcium sulfate is normally ground up with the clinker The gypsum controls the setting properties of the cement when water is added The basic components of the cement production process
Clinker and gypsum for OPC limestone for limestone cement and slag for slag cement are all extracted from their respective hoppers and fed to the cement mills The ball mill grinds the feed to a fine powder in two chambers namely the first and second chambers
The clinker is a kiln outlet which is the main cement ingredient The limestone is used only for the cement production for certain cement types in the cement mill as a mineral component The raw materials from the depo centre are transported to the vertical roller mill where raw meal is produced
Cement manufacturing brief description of a cement mill Cement clinker is usually ground using a ball mill This is essentially a large rotating drum containing grinding media normally steel balls As the drum rotates the motion of the balls crushes the clinker The drum rotates approximately once every couple of seconds
Clinker the discharge product from the kiln is partially cooled and broken or crushed to about ¾" – 1″ as feed to finish mills Fineness of grind is dependent upon the type of cement to be produced Since fineness of grind falls below standard screen size accuracy fineness of grind is determined by use of a "Wagner'' Turbidometer
Cement mill is the key equipment for crushing after the material is broken Cement mill is widely used in cement silicate products new building materials refractories chemical fertilizers black and nonferrous metal mineral processing and glass ceramics and other industries
We have supplied vertical roller mills VRM for raw coal slag and cement grinding for several decades The vertical roller mill is well known in the cement and power plant industries as the preferred mill for grinding of raw materials It is increasingly used as a solution for efficient grinding
As a kind of cement grinding machine Cement mill is the equipment used for grinding the hard nodular clinker from the cement kiln into the fine grey powder that is cement Cement grinding mill is normally driven by electric motors The output achieved by a cement mill system varies with the mill power the fineness of the product and the hardness of the clinker Cement grinding mill is the last process of

That is Portland cement was first produced by a British stone mason Joseph Aspdin in 1824 who cooked cement in his kitchen He heated a mixture of limestone and clay powder in his kitchen and grind the mixture into powder creating cement that hardens when mixed with water
Raymond mill is a common cement mill of cement plant and generally apply for production of mineral powder or coal powder such as the fine powder processing of raw ore gypsum coal and other materials
