Definitions

  • Patent no. ES 9300185/PCT 9400009 described the possibility of sawing with sludge containing low percentages of sawing detritus where the supporting power is due to the presence of fine, soft powders that allow to reduce the total cost of the sawing to a third and simultaneously treble the production, but this solution has not been applied yet due to the high investment needed for its application.
  • composition of the sludge entering the machine excluding the grit, would be less than 66% for rock particles, over 28% for lime water and more than 6% for fine, soft materials; with the volume and according to the characteristics of the rock to be sawed.
