The basic difference is the percentage of clinker & additives used [4]. Now a days Cement plants are producing 75–80% PPC & 20–25% OPC due to high market demand of PPC. Production of PPC is cheaper and it's market rate is also lower than OPC by nearly 25 rupees per bag, so general consumer are attracted towards PPC cement.

What is Cement Clinker? Composition, Types & Uses

Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary ...

Here's an exploration of the role of clinker grinding in the cement manufacturing process: Particle Size Reduction: The primary purpose of clinker grinding is to reduce the particle size of the clinker. The raw clinker typically consists of clumps …

CEMENT SikaGrind® FOR VERTICAL ROLLER MILLS

In a VRM the grinding takes place by pressure and shear force. The clinker passes within seconds between roller and table. The energy input to the material during one passage between grinding rollers and grinding track is relatively low. The thick-ness of the material bed between roller and table is a multiple of the particle size.

The result is called clinker, which are rounded nodules between 1mm and 25mm across. Step 5: Cement grinding After mixing with gypsum and admixtures, the clinker is sent to a cement mill for grinding. Cement grinding can be carried out either in an integrated cement plant or in a stand-alone cement grinding station. 3.

Clinker Cooler

Clinker leaves the cement kiln usually at more than 1200℃ and it carries the heat content about 1250-1650 kJ/kg. So it needs to be cooled in order to: improve the cement quality and the grindability of clinker. When the clinker is rapidly cooled, the formation of mineral crystals in it is inhibited. Even if some of them have crystallized ...
