Definitions

  • the present invention relates to an automatic system for setting the density and viscosity in products obtained by continuous grinding, being especially applied in the field of the ceramics sector but also in any sector wherein the continuous wet grinding is used.
  • the solution being set forth has an immediate application in continuous grinding because it improves the quality and control of the supplying process. This will allow eliminating the reworks for correcting the characteristics of the barbotine once in the pool, as long as deviation allows this, such as for example a high density that can be corrected by adding water. On the other hand deviations difficult to be corrected may exist, as would be the case opposite to the previous one wherein the density was below the set point in which case the only way for recovering is by adding it to barbotine pools with a density higher than that of the work.
  • the automatic system for setting the density and viscosity in products obtained by continuous grinding, object of the present invention involves a solution based on continuously measuring the moisture from the mixture of solid raw materials entering the continuous mill, wherewith the required amount of water to be supplied could be set, so that water has to be also measured.
  • suspended materials such as can be recycle sludge or any diluted raw material
  • it will be required to measure the solids content in that suspension by being another source for possible variations in the amount of water supplied to the mill. Therefore, maintaining both the viscosity and density of the final barbotine in steady values is expected.
  • the density and viscosity in the barbotine resulting from the grinding will be measured by using an off-line system, i.e. equipment that enables carrying out a sampling of the barbotine in order to maintain a continuous measurement, while minimizing the wears caused by the abrasive action of the barbotine and facilitating the controlled cleaning of sensors.
  • an off-line system i.e. equipment that enables carrying out a sampling of the barbotine in order to maintain a continuous measurement, while minimizing the wears caused by the abrasive action of the barbotine and facilitating the controlled cleaning of sensors.
  • Figure 1 It is a scheme for carrying out the installation of an automatic system for setting the density and viscosity in products obtained by continuous grinding, according to the invention.
  • the first objective is to maintain the density and viscosity in steady values, for which the setting would be needed when raw materials enter the continuous mill. This is important because the residence time of the barbotine inside the mill is very high. So that, if the setting were made based on the reading of the barbotine density, there is a risk that the conditions of raw materials that caused that density found at the outlet be the same conditions entering at this time in the continuous mill. This shift in time can cause an instability even greater than that which may exist through normal supply of raw materials, water, and deflocculant.
  • the water will be set by using the system available when installing the mill (automated control valve, peristaltic pump ...) and it will be measured using a flow meter providing the required accuracy. Through this setting of the water supply, an steady density is expected to be maintained, since the proportion of different raw materials is assumed constant, and fluctuations that may occur in the flow rate of raw materials entering the mill can be balanced with the setting of water flow rate, by having these under control using the extracting/dosing belt 12.
  • the scheme also indicates the cleaning water inlet 13 and the air inlet and outlet 14.
