What is Calcium Carbonate? Calcium Carbonate is a mineral that is used in a wide array of industries including plastics, paints, pharmaceuticals, construction and agriculture. It is both naturally occurring and can be produced synthetically as well. Furthermore, Calcium carbonate is commonly used in dietary supplements in food and medicines. Sieving calcium carbonate is a necessary process in order to meet the precise particle size requirements for the industries it is used. Calcium carbonate can prove difficult to screen due to the finer mesh sizes needed to separate it as well as its tendency to agglomerate and stick together which can lead to significant screen mesh blinding. Sieving calcium carbonates at fine sizes and high rates is a tedious task when using traditional vibratory sieves and ultrasonic sieves and can quickly blind and overwhelm the screen leading to poor processing efficiencies and rates.
