Comparing ball mills and VRMS for cement grinding
The equipment costs are higher for a VRM than a ball mill, reflecting the greater complexity of the system, which includes items such as the rollers, table and the hydraulic system. Overall, when equipment, erection and civil costs are taken into account, the cost of a VRM project is around 20 – 25% greater than a ball mill system of the same ...

Digitization and the future of the cement plant McKinsey
There’s never been a more important time to build resilience into the core of the cement value chain: the cement plant. The cement industry is being hit hard by the COVID-19 pandemic, with global demand for cement expected to decline by 7 to 8 percent in 2020—though these declines have been unevenly distributed across regions. 1 Paul

Cement - Wikipedia
Cement is seldom used on its own, but rather to bind sand and gravel ( aggregate) together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete. Concrete is the most widely used material in existence and is behind only water as the planet's most-consumed resource.
