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

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
