Plant P9: The plant P9 produces 4.42 Mt of cement (OPC and PPC) with an estimated energy consumption of 6.1 × 10 6 M kcal. This unit also exports power to the grid. In this section, the plants are compared on the basis of specific parameters. The comparison showcases the diversity that exists between the cement plants.
The grinding process consumes the most energy in the cement production, its energy consumption accounts for more than 70% of the total power consumption in the whole process of cement production. There are three main grinding processes in the cement production: raw meal grinding, cement grinding, and raw coal grinding.

The number of VRMs installed for cement grinding trends higher due to better overall power efficiency and lower maintenance costs. One example is the Guinness World Record largest VRM for cement grinding at Shah Cement in Bangladesh. That mill regularly produces both PPC and PSC Cements as shown in Table 2.
The mill is designed to produce Ordinary Portland Cement (OPC), Pozzolana Portland Cement (PPC), Portland Slag Cement (PSC) and slag cement types. It is producing PPC at a capacity of 500t/hr at 3500 Blaine with 15% slag. In addition to the OK Mill, FL supplied the process and layout engineering, along with site advisory.
Subaru's EJ255 engine was a turbocharged 2.5-litre horizontally-opposed (or 'boxer') four-cylinder engine. For Australia, the EJ255 engine was introduced in the Subaru SG Forester XT in 2003, but subsequently offered in the GD/GG Impreza WRX and BL Liberty GT (see table below). Developed in conjunction with the more powerful EJ257 engine, key features for the EJ255 engine included its:

Average cement consumption in Spain in the last 50 years was 25Mt/yr. However, consumption spiked to more than 50Mt in 2007, and has plummeted to just over 10Mt in 2016, a demand level last seen in the 1960s, precipitating a huge crisis in the cement and construction industry. Spain is the largest exporter of cement and clinker in Europe.
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 ...
