· Portland Pozzolana Cement PPC The Portland Pozzolana Cement is a kind of Blended Cement which is produced by either inter grinding of OPC clinker along with gypsum and pozzolanic materials in certain proportions or grinding the OPC clinker gypsum and Pozzolanic materials separately and thoroughly blending them in certain proportions Also Read How To Calculate Number Of Blocks
As the grinding process requires a significant amount of power finer grinding for the 53 grade OPC requires more power and is therefore priced higher compared to lower grades of OPC Chemical Composition This a very high strength cement this is obtained because of very high percentage of C3S content in the clinker about 52 53% 95% clinker is grinded with 4 to 5 % of gypsum to make this
One mill and one silo may be reserved for OPC with the rest for whatever type s of cement PPC/BFSC are to be made If a cement plant is making both PPC and BFSC which is quite possible groups of mills will be reserved for each category so as to avoid changes of settings cleaning of silos to avoid contamination etc Dispatches
were interground with clinker and gypsum in a laboratory ball mill to compare the power consumption with ordinary Portland cement OPC 95% clinker and 5% gypsum The ternary blended cement took less time to reach the same fineness level as OPC due to soft pozzolana and high grade lime stone indi cating that intergrinding may reduce overall power consumption Blended cem ent production
modern vertical roller grinding mills along with tube mills both for raw meal as well as coal Cement grinding is achieved exclusively by tube mills/horizontal ball mills The final products of the plant include PPC OPC PSG and other special cements The major markets are Tamil Nadu Kerala Karnataka Andhra Pradesh Pudducherry etc 2 PROCESS DESCRIPTION The production of cement involves
Portland Pozzolana Cement PPC 1 OPC is prepared by a completely automated dry production process by grinding argillaceous calcareous material to gypsum PPC is produced by inter grinding well burned clinkers with gypsum and pozzolana materials such as fly ash or silica power plants 2 In OPC permeability is more than PPC

· Portland cement can be made by following two different processes a dry one and a wet one Joseph Aspdin first made portland cement in his kitchen stove in England in the 19th century Lime and silica make up approximately 85% of portland cement The materials that are commonly used are limestone shells chalk shale clay slate silica sand and iron ore
Suitability of various types of cement Selection of cement based on suitability for various concreting environment is important for durability considerations of structures Thus making wise choice of cement type for particular construction site
In most PPC manufacturing processes pozzolanic ashes are added to the cement clinker in the cement grinding step There are two ways to manufacture Portland pozzolana cement 1 Grinding ordinary Portland clinker along with pozzolanic materials and additional gypsum or calcium sulfate 2 Grinding OPC clinker and pozzolanic materials separately and then mix them together with gypsum
· The difference between OPC and PPC is that in PPC fly ash is added as one of the raw material to improve the fineness of the cement Thus the production level and the operating range is different for OPC and PPC A typical operator station for the cement mill circuit is shown in Figure 3 All the signals coming from the sensors of the grinding process are collected in an ECS SCADA
09/01/2019· 6 Differences between OPC and PPC cement i OPC has shorter setting time compared to PPC ii OPC has higher initial strength compared to PPC iii OPC cannot be used for mass concreting due to its high heat of hydration whereas PPC can be used for mass concreting iv OPC is less durable compared to PPC v OPC provides lower resistance to aggressive chemicals compared to PPC vi OPC is usually costlier than PPC
· This mill is also equipped with a 6700kW drive unit and the order follows another grinding plant for Shree Cement with the same mill type in Saraikela Kharsawan district Jharkhand India The company has also been increasing its cement capacity in southwestern India where it commissioned a new 3Mta integrated plant in Kodla village near Gulbarga Karnataka in June 2018
28/05/2020· Strength of OPC and PPC From the above data we can conclude that initial strength of OPC cement is higher than PPC cement But for long term strength Portland Pozzolana Cement is higher than Ordinary Portland Cement So it is clear now if you need higher strength in initial stage then go for OPC otherwise go for PPC
As the grinding process requires a significant amount of power finer grinding for the 53 grade OPC requires more power and is therefore priced higher compared to lower grades of OPC Chemical Composition This a very high strength cement this is obtained because of very high percentage of C3S content in the clinker about 52 53% 95% clinker is grinded with 4 to 5 % of gypsum to make this
