In this third blog we describe the use of density to prevent problems with circulating load and as variable in a back-up system for the particle size analyzer (PSA). If the cyclone keeps returning ore to the ball mill, the total volume of ore will be increasing in the grinding circuit, as is the density of the slurry.

One way to prevent cement from ending up in landfills after its shelf life is to regain its activity and reuse it as a binder. As has been discovered, milling by planetary ball mill is not effective. Grinding by collision is considered a more efficient way to refine brittle material and, in the case of cement, to regain its activity. There has been considerable research regarding the …

An energy harvesting and measurement device that is operable in at least a normal operation mode, a demand measurement mode, and a fault measurement mode. The device includes a current transformer and a device circuit. The device circuit includes an energy harvesting circuit with non-linear elements, a switching device, a microcontroller and a high current sensor.
power draw. Estimation of the ball load that is mixed with the cement charge is difficult and can be highly erroneous. So direct measurement must be taken for calculation of mill load. A direct measurement of the load entails the crash stopping of the ball mill under load whilst the mill is running under steady state conditions. Before

Strain gauge load cells are by far the most common type of load cell-based weighing system in 2010. Strain gauge load cell weighing systems convert weights into analog output signals that can be further conditioned to indicate weight in digital meters and control systems.
So far, the main method to measure the ball mill load are direct and indirect methods. The direct method has been put forward in the international mineral processing congress at 1973. The direct method use pole to measure the height of ore pulp liquid level to get the load. It cannot be popularized since the problems of pole damage

Load behaviour, mill power and breakage as affected by media shapes were studied in a pilot laboratory mill. An inductive proximity probe, light emitting diode, phototransistor and video photographs were used to determine the load orientation in terms of toe and shoulder positions. A load beam was used to measure the torque exerted by the charge.

the mill with ore up to the point where maximum mill power draw is registered. At maximum power draw it is assumed that the void spaces within the ball load are filled with ore particles and that the charge is well mixed. In order to conduct the study an inductive proximity probe was used to measure the dynamics of the load behaviour.
Mill capacity increases linearly with increasing ball load for both ball sizes within the considered range. The 30 mm ball draws slightly more power as J increases from 11 to 16% but the gain in capacity is much more. In fact for an increase in J from 11 to 16% (i.e. 45% increase), power draw increase is 31%, while capacity increases by 51%.
Ball milling is a type of grinder used to grind materials into fine powder. Ball mills rotate around a horizontal axis, partially filled with the coarse salt to be ground plus the grinding medium. There are many types of grinding media suitable for use in a ball mill, each material having its own specific properties and advantages.
