According to Indonesian Standard SNI 15-7064-2004, Portland Composite Cement (PCC) or blended cement is defined as a hydraulic binder which consists of clinker, gypsum and one or more inorganic materials where their contents range from 6% to 35% of the total mass of PCC. However, some factories still have their clinker levels in PCC above 80%.

cement grinding process in the presence of clinker heterogeneity is a challenging task. The model predictive controller (MPC) poses a viable solution to handle the variability. This paper addresses the design of predictive controller for the cement grinding process using …
Of the 159, 141 produce clinker and 18 countries only grind imported clinker. For comparison, the comparable data presented in our December 2016 issue showed that there was a total of 158 countries and territories making cement and clinker, with a total integrated and grinding cement capacity of 2.69Bnt/yr, excluding China.
Clinker grinding is the stage in which the final product stage in cement production,it is independent of each other. In this stage, the cement clinker is added with an appropriate amount of the mixed material,it is be ground to produce finished cement. The electric motor drives the disc through the reducer, and the hot air enters the vertical ...
Final Grinding and blending The black, nodular clinker, gypsum and fly-ash are stored in separate hoppers ready to follow the course of final grinding. From the hoppers the clinker along with gypsum and fly-ash are ground together in ball mills in defined proportions to form the final cement products.
This is an experimental study which explores the physical, mechanical, and economic factors involved in the production of type CEM II A-B/W cement. In this context, 4 cement additives were used in two different dosages (200 and 800 g/t). Class C fly ash was used for composite cement production at ratios of 5%, 20%, and 35%.
The grinding costs of clinker are smaller than this cost difference. Furthermore, if clinker is imported then several types of cement can be produced from that clinker, allowing greater flexibility to meet the specific and possibly changing local market demands. Finally, with a grinding plant, additional efficiencies can be obtained by ...

It was developed for other types of hydraulic lime in England in the early 19th century by Joseph Aspdin, and usually originates from limestone. It is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker, grinding the clinker, and adding 2-3% percent of GYPSUM. Several types of Portland cement are available.
