Calcium carbonate mud (carb-cake) is pressed, washed, and squeezed under pressure in fully automatic mud presses to reduce its sugar and moisture content, the produced press mud contains around 25% moisture (w/w) as measured by loss on drying (LOD). The resulting mud press looks like aggregates of small gravels thatâ??s composed of microcin sized crystals. The Flow characteristics of such aggregates are very poor and makes it difficult to fill the trailer of disposal truck which requires more journeys to dispose the whole quantity. Below are the physical and chemical properties of the produced wet carbo-cake Main Constituents in (wt%) SiO2 3.82 TiO2 0.03 Al2O3 0.9 Fe2O3 0.38 MgO 0.61 CaO 44.73 Na2O 0.22 K2O 0.2 P2O5 0.4 SO3 0.96 Cl 0.03 LOI at 550C 30 LOI at 1000C 48 Rb2O 0.001 MnO 0.019 NiO 0.005 CuO 0.012 ZnO 0.004 SrO 0.013 Dried Carbo-cake converts it into free-flowing powder with a bulk density of 1.1 and reduced weight in total resulting in reduction moisture to less than 5% and increasing its flowability characteristics Areas of application Concrete ready mix Filler in paper industry Filler in plastic manufacturing Filler in concrete mix to adjust some physical and chemical properties
