Limestone and gypsum (additions) are taken from a cement mill doser (BK IV) and they dried in an oven at 105°C and 60°C, respectively to facilitate crushing and to prevent clogging in the mill. Fly ash is taken from a cement mill doser (BK IV). They have a dry fine nature and they don't need any grinding or drying.

flow effects can occur with a funnelflow pattern. p Figure 5. Massflow discharge occurs when material flow is achieved against the sloping hopper walls. A massflow pattern prevents ratholing, allows firstin/firstout flow, and minimizes segregation. Table 1.
The ball mill is a key equipment for grinding materials, widely used in powdermaking production line such as cement, silicate sand, newtype building material, refractory material, fertilizer, ore dressing of ferrous metal and nonferrous metal, glass ceramics, etc. Ball mill .
Effect of clays on the mechanical properties of rocks. There have been few systematic studies of clay effects on the mechanical properties of rocks. Corbett et al. demonstrated how the coefficient of internal friction and thus the strength of Austin chalk strongly depends on even a small clay fraction (Fig. 6).

However, there are many other concerns. Beyond the physical changes to the landscape, the daily barrage of noise, dust and exhaust produced by hundreds of dump trucks hauling aggregate can have serious effects on the health of people living nearby.
Limestone quarries benefit the local community by means of available jobs for locals. There are also local infrastructure benefits such as improved access routes and new power lines. Read More

This is achieved in a cement raw mill. The grinding process is controlled to obtain a powder with a broad particle size range, in which typically 15% by mass consists of particles below 5 μm diameter, and 5% of particles above 45 μm.
Opportunities for energy efficiency improvements are also reviewed. The results suggest that cement plants are good candidates for DR participation. The cement industry consumes over 400 trillion Btu of energy annually in the United States, and consumes over 150 MW of electricity in California alone.
SCE and its third party implementer state that limestone and other additives — together referred to as finish mill system additives — produce a fluxing effect and reduce specific energy consumption (kWh per ton). SCE estimates that the project would realize an annual energy savings of 9,379,927 kWh and a peak demand reduction of 1,162 KW.

Grid Power is an energy system added by Extra Utilities 2.. In addition to, or instead of Redstone Flux, some Extra Utilities 2 items require Grid Power. Unlike other energy systems, Grid Power is playerspecific, wireless, rangeless and cannot be stored.
the mill can be controlled by a recycle pump to affect the product size distribution, prevent over grinding, and reduce the circulating load from the cyclone.
