Heat balance calculators

Heat balance calculators

Heat balance calculators. The calculation of the thermical balance of the ball mill is now proposed according 2 methods: - The first method, we know the ventilation of the mill + the cement temperature and we want to calculate the water quantity we need to inject in order to get the temperature at mill outlet we would like to have. - The second method, we know the ventilation inside the mill + the quantity of water injected and we calculate the temperature of the cement at mill …

Cement Process amp Energy Saving

Cement Process amp Energy Saving

Addition of Grinding Balls Watch raw mill SEC daily and add grinding balls in right timing →10% energy saving expected Ball diameter shrinks as time passes due to erosive effect. This leads to gradual increase of raw mill SEC. Filling level of grinding balls is also important in grinding efficiency. Optimum level of filling should be maintained.

The cement mill

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.

The Critical Speed for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell's inside surface. This is the rotational speed where balls will not fall away from the mill's shell. Result #1: This mill would need to spin at RPM to be at 100% critical speed. Result #2: This mill's ...
