Measuring ball mill ventilation | GCP Applied Technologies
It is preferable to measure the air velocity entering the mill inlet using a simple hand-held anemometer. This will indicate the actual air flowing into the mill and will discount the impact of false air. ... A simple check for the degree of false air is to compare the mill cement exit temperature with the mill gas exit temperature. As the ...

The cement mill
Cement manufacturing - brief description of a cement mill. 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.
Concrete Grinders & Planers for Rent
Concrete grinders (sometimes called concrete sanders) remove material up to 1/8 of an inch below a concrete surface per pass. Rent a concrete grinder if you need to remove surface materials such as paint, epoxies, stains and other coatings. A concrete scarifier, aka concrete planer or milling machine, removes up to 1/4 of an inch per pass.
