Raw materials are extracted from the quarry, then crushed and ground as necessary to provide a finematerialfor blending. Most of the material is usually ground finer than90 microns- thefinenessis often expressed in terms of the percentage retained on a90 micron sieve.

Lime Component Limestone: Common forms of calcium carbonate used asraw materialforcementmanufacturing 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.
There are four stages in the manufacture of portland cement: (1) crushing and grinding the raw materials, (2) blending the materials in the correct proportions, (3) burning the prepared mix in akiln, and (4)grindingthe burned product, known as “clinker,” together with some 5 percent ofgypsum(to control the time of set of the cement).
Crushed stoneis also required forcementbased products likeRCC pipes,PSC poles,cement concrete hollow blocks,precast cement concrete slabs, well rings, window & door frames and road laying. The demand for crushed stone will continue to grow with the growth of its user industry.
Thus, the quantity ofcementrequired for 1 cubic meter of concrete = 0.98/0.1345= 7.29 bags ofcement. The quantities ofmaterialsfor1 m3 of concreteproduction can be calculated as follows: The weight ofcementrequired = 7.29 x 50 = 364.5 kg. Weight of fine aggregate (sand) = 1.5 x 364.5 = 546.75 kg.
The choice of composition ofmaterialsmixture with useful components generally is determined by plant’s geographical location and delivery ofraw materials. The only common feature in allcementproduction plants is the difficulty of grinding the sourcematerialas thematerialis hard enough and has high abrasiveness.
Quarry operations consist of drilling, blasting, excavating, handling, loading, hauling, crushing, screening, stockpiling, and storing. Raw material preparation. The raw material preparation comprises of the following operations: - Crushing - Pre-Homogenization (Stockpiling) - Raw material proportioning, drying and grinding - Blending and kiln feed Crushing
-crushingand grinding ofraw materialin acementin-Incementproduction process,cementcrusher is very important since most ofthe raw materialswill have to be crushed before being used to processcement, such as limestone, clay, iron ore and coal, etc. Limestone is the largest amount ofraw materialduringcementproduction.
Crushing The Raw Materials Of Cement- Typicallycement raw materials crushingplant locations are based upon the Jaw crusher is a primarycrushingequipment which can be used forcrushingCrusher ore crusher p. or to reduce the size of a solid mix ofraw materialsthe fixed jaw due to the action of toggle plate and vertical crusher can.
Raw materials usedformanufacturing ofPortlandcementare found naturally in the earth’s crust. It is made primarily from calcareous and argillaceousmaterialsand gypsum. Calcareousmaterialscontain limestone or chalk while argillaceousmaterialscomprise an oxide of silica-alumina and iron. Both are found as clay or shale.
PreparationOf Cement Raw Material CementMill,Cement.Crushing: the limestone and othermaterialsare crushed into small pieces bycementcrusher, such as hammer crusher, cone crusher, jaw crusher, impact crusher, etc. Mixing: according to the requirement of clinker, compound desiredraw materialforcementproduction line.
Cement manufacturing process & what is cementmade of, it can be discussed conveniently under two headings: Selection ofRaw materialsand manufacturing methods.Raw Materials of Cement. Most importantraw materials(what iscementmade of) required in the manufacture of PortlandCementare: Limestone, Clay, Gypsum, Fuel, and Water (in wet method).

The former is used for driving the machinery tocrush, grind, mix and temperthe raw materialfor Portlandcementand the other for grinding the burnt clinker and naturalcement, as well as for hoisting the stone from the quarry to the kilns and crushers.
Raw materialproportioning. The homogenized limestone and clay/silcastone along with otherraw materialslike sand and iron ore are reclaimed into separate feed bins. The proportional ratio ofthe raw materialsis fixed usingrawmix design and is determined from the chemical analysis ofthe raw materials.
Stone Crusher PlantMachines &Raw Materials.Stone crusher plantmachinery depends on the feed size of the stone, the desired product size and the size of the crusher used. Following are the generally required machinery. Jaw crusher and granulator; Conversion kit for converting crushed stone granules; Set of hoppers for manual breaking.

Concretemanufacturers expect theirraw materialsuppliers to supply a consistent, uniform product. At thecementproduction factory, the proportions of the variousraw materialsthat go intocementmust be checked to achieve a consistent kiln feed, and samples of the mix are frequently examined using X-ray fluorescence analysis.
How Cement is Made(Video) 1. Miningthe raw material. ...Crushing. The quarry stone is delivered through chutes to the crushers, where it is reduced bycrushingor pounding to chunks approximately 1 ½ inches in size. 4. Prehomogenization.
Raw MaterialPreparation. Typically,cement raw materials crushingplant locations are based upon the availability of good quality limestone in the vicinity. The quarrying operations are done by thecementproducer using the open cast mining process.
