VG: At best, coal mill safety is not well understood and, at worst, it is ignored. When it comes to coal mill systems, most cement plant operators just presume that the supplier of the equipment knows all of the standards and rules and is capable of making a system that conforms to these and is therefore safe. However, this is not the case.

Grinding systems in cement production make up approximately 85 to 90 percent of total plant electrical energy consumption. As vertical roller mills are 30 to 50 percent more efficient than other grinding solutions, they give cement plant owners a great opportunity to. maximise productivity and minimise operating costs.

Cement emissions intensity has remained relatively stable since 2018, at just under t CO 2 per tonne of cement produced, following several years of modest increase largely due to an increasing clinkertocement ratio in China. To get on track with the NZE Scenario, emissions must fall by an average of 3% annually through to 2030.

There are four stages in the manufacture of portland cement: (1) crushing and grinding the raw materials, (2) blending the materials in the correct proportions, (3) burning the prepared mix in a kiln, and (4) grinding the burned product, known as " clinker," together with some 5 percent of gypsum (to control the time of set of the cement).

As a highcarbon and energyintensive product, manufacturing cement, the key ingredient in concrete, takes a heavy toll on the climate. The Redding factory emitted about 282,000 tons of carbon dioxide in 2020 — equivalent to about 55,000 gaspowered cars.. Under pressure from state lawmakers, California's cement industry is gradually taking steps to reduce its carbon footprint.
