A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.

We use a closed-circuit grinding process to obtain a very finely ground cement. A size particle range of 3 to 30 microns (one micron is a thousandth of a millimeter!) results in the most efficient hydration of cement and better strength properties, including more late strength. The Wonder Cement factory process is now complete.

Selecting the correct angle grinder for concrete grinding purposes is very important. You can choose either a 4-inch angle grinder or one that is 4 ½ inches. These are considered the best for most concrete grinding tasks. It may also be a good idea that you choose a tool with a motor that is able to draw anywhere between 5 – 9 amps.

concrete, brick, and mortar. When workers cut, grind, drill, or crush materials that contain crystalline silica, very small dust particles are created. These tiny particles (known as "respirable" particles) can travel deep into workers' lungs and cause silicosis, an incurable and sometimes deadly lung disease.

Grinding aids are organic compounds that are added to the mill during cement grinding. Their main purpose is to reduce the energy required to grind the clinker into a given fineness. In addition, some products (usually referred to as performance enhancers) provide positive effect on cement hydration improving strength development [1].

The majority of CO 2 produced during cement manufacture arises during clinker production, due to the calcination of calcium carbonate, fossil fuel burning and electricity consumption (mostly for grinding). Using a base CO 2 factor of 862kg CO 2 /t clinker, each one percent drop in clinker in cement can reduce emitted CO 2 by 8-9kg/t cement.
