Ultra Fine Grinding

The effects of technology condition and performance of calcium carbonate/titanate composite material (CCTCM) prepared by mechano-activated method were studied in this paper. The results show that CCTCM can be prepared by the surface modification of calcium carbonate using titanate as a modification agent incorporated with the simultaneous wet ultra-fine grinding, and the modification results and performance of composite material are affected by the grinding condition of calcium carbonate. CCTCM has good application characteristics from its physical property and the performance of packing polyethylene (PE).

Enhancing the extraction rate is one of the key objectives in optimization of extraction of substances from biogenic raw materials. Ultra-fine grinding of plant raw materials (to achieve particle size less than 300 µm) is a very appealing method for increasing the extraction rate using relatively simple equipment. However, this approach often fails to yield the desired result. This study focuses on the kinetics of melanin extraction from two types of raw materials: fungus Ganoderma applanatum and buckwheat husk. Particle size is shown to be just one of the key factors. The degree of order of plant-based feedstock strongly affects the intraparticle diffusion constants and can be a parameter controlling the diffusion rate. It has been shown that there exist optimal degrees of disorder of the crystal structure of plant raw materials, which have a dome-shaped dependence pattern and allow one to increase the diffusion coefficient by several dozen times. The kinetics of melanin extraction was described by some kinetic models that include the first order equation, the Baker and Lonsdale model, the Axelrud equation, and the Ritger–Peppas model.
