deagglomerated by a hammer mill, ball mill or a V-separator (see Figure 3). A HPGR can reduce energy consumption when working as a pre-grinder ahead of a ball mill, with savings of around 1.8-2.5kWh/t for clinker and 2.5-3.8kWh/t for GBS.10 Conclusion To reduce the clinker factor while still developing concrete strength requirements,
1. Introduction. Clinker milling is the last step in production of Portland cement. Nodular clinkers produced in a rotary kiln in a cement plant are ground together with gypsum into a fine powder of particle size less than 100 μm and with a surface area of 330–380 m 2 /kg for production of ordinary Portland cement (Bye, 1999).The fineness of …
The production and clinker capacity of countries in 2015 and 2016 are summarized in Table 1 [9]. China is the leader on both cement production and clinker production, accounting for more than 50% of total production. Top two countries, China and India, make up about two-thirds of total cement production in the world.

In raw grinding, a ball mill with a high efficiency separator is used to achieve uniform particle size in raw mix for the next stages of the manufacturing process. At the Cement Grinding Stage, 90 – 95% of the clinker is mixed with gypsum and ground in a Cement Ball Mill to produce quality cement OPC 43 and OPC 53. In case of PPC Cement ...
Clinker is extracted from our clinker tank and transported to the cement mill hopper by belt conveyors. A measured quantity of clinker and gypsum is fed into our closed-circuit ball mill which incorporates with a high-efficiency separator. OPC is produced by the inter-grinding and blending of 95% clinker with 5% gypsum to a fineness of 280 m 2 /kg.
The main purpose of the cement ball mills is to grind the clinker and gypsum into a finer powder to produce the final cement product. In addition to grinding clinker and gypsum, ball mills can also be used for grinding other materials such as slag, pozzolan, dolomite, and fly ash. These materials are added to the cement to improve its ...
Clinker grinding technology is the most energy-intensive process in cement manufacturing. Traditionally, it was treated as "low on technology" and "high on energy" as grinding circuits use more than 60 per cent of total energy consumed and account for most of the manufacturing cost. Since the increasing energy cost started burning the benefits …
Clinker, Gypsum and other desired additives are fed to the ball mill in specific proportions based on the quality requirement. Feed material is ground in the ball mill, discharged and fed to a classifier with the help of bucket elevator for classification of the ground cement into two a streams – coarse and fines.
