Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds. The drum is generally divided into two or three chambers, with different ...

One mill and one silo may be reserved for OPC, with the rest for whatever type(s) of cement (PPC/BFSC) are to be made. If a cement plant is making both PPC and BFSC (which is quite possible) groups of mills will be reserved for each category so as to avoid changes of settings, cleaning of silos to avoid contamination, etc. Dispatches

Start by measuring the area of the project. Determine how long and wide it is, then multiply those two numbers to get the square feet. Then, measure the depth of the project, and multiply that by the square feet to find out how many cubic feet of concrete you will need. Make sure your depth is in feet and not inches.

A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage [1]) 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.

The gravel doesn't effect the tensile strength of the concrete unless you add so much there isn't enough cement paste to fill the voids in the finished concrete, and it merely acts as a filler, taking up space. Adding too much gravel can make it difficult to get a smooth finished surface on the cured concrete.
