Process optimization of nano-calcium carbonate produced from snail shell using supermasscollider

This study uses the optimal (custom) design to focus on the supermasscolloider wet milling process for synthesizing calcium carbonate nanoparticles from the Achatina Fulica using the optimal (custom) design. The snail shell particle size of 150 mu m from dry milling was wet milled to get smaller particle sizes. The response surface design method was used to investigate the effect of independent parameters such as consistency (amount of microparticle loading in calcium carbonate suspension) and the number of runs on the particle size of calcium carbonate produced using a supermasscolloider. Results show that the microparticle loading in calcium carbonate suspension and the number of runs significantly affected the synthesized particles. The increase in microparticle loading reduced the effectiveness of the supermasscolloider blade, resulting in the production of particle sizes ranging from 21- to 40 nm. A higher number of runs with a smaller loading of microparticles in calcium carbonate suspension offered a fine particle size of 21.30 nm. The experimental data quartic polynomial models gave a coefficient of determination (R2) of 0.92. The optimum milling runs of 750 and 1% consistency microparticle loading produced a calcium carbonate nanoparticle size of 21 nm. This technique has shown that calcium carbonate nanoparticles can be produced at low cost, at less period, with low agglomeration from Achatina Fulica shell using supermasscolloider.
