Soft sensor for real-time cement fineness estimation
Fig. 1 shows a simplified scheme of the cement grinding circuit that indicates process variables of interest in this paper. Material flow is indicated with solid lines, whereas dotted lines represent air flow in the circuit. Clinker and additives are transported from their bunkers via conveyor belts and are fed into the ball mill, which consists of two chambers.
Bin Level Indicators and Flow Detectors | AIRMATIC
A bin level indicator (also referred to as a bin level sensor) is a device or system used to measure and monitor the level of a stored powder or bulk solid material in a bin, silo, hopper, or other container used as part of a bulk material handling process. There are two major categories of bin level indicators available: The first offers ...
Process Training Ball Mill
The better mills on the market have an efficiency of about 8-9 % which means that only 8-9 % of the energy results in grinding and the majority is converted mainly into heat. The ball mill has the worst efficiency of all types of mills on the market. Just 4 % of the energy is used for comminution. Nevertheless when grinding is required the ball ...

The 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 drum is generally divided into two or three chambers, with different ...
Hydraulic Oil Level Sensor Designed for Cement Grinding Mill
The sensor is designed for high temperature operation up to 125ºC, with the main probe section rated to 150ºC. The sensor is factory-calibrated to provide a 0.25V to 4.75V analogue output over the full 49mm measurement range. Eight sensors have been manufactured and supplied for extensive testing on the first prototype cement grinding …
Mill control using millScan g4
Fixed position sensors are able to detect changes to 1/10th of a per cent in fill level accuracy which then equate to +/- 0.01 mA on the 4-20 mA fill level output signal fed back to the control room. The shell based sensors are typically not as accurate but still far superior for mill control than a microphone based system.
