Wet Grinding Process: how it works and what industrial equipment is used<\/h2>\n

Wet grinding <\/b>is an industrial process in which the movement of ceramic microbeads is used to separate solid particles incorporated in a liquid medium and, in some cases, reduce their size. The rotational and linear movement of the microbeads generates impact, friction and shear forces. Through this action, homogeneous distributions of solid particles in the base liquid are obtained in the manufacture of products such as paints, pigmented varnishes, enamels, nail varnishes, phytosanitary products, printing inks, etc.<\/span><\/p>\n

What is wet grinding?<\/h2>\n

Wet grinding<\/b> processes mixtures of solids in liquids, which are essentially fluids or may present variations in viscosity. This process is used in the manufacture of paints, pigmented varnishes, enamels, nail varnishes, phytosanitary products, printing inks, etc.<\/span><\/p>\n

In this process, agglomerates that were not separated during the <\/span>pre-dispersion stage<\/span> (due to electro-physical bonds between certain components) are broken by applying additional energy generated by the movement of ceramic microbeads.<\/span><\/p>\n

For this <\/span>wet grinding<\/b> process, beads or <\/span>microbeads<\/b> are used. They are accelerated inside a chamber thanks to the movement of rotating discs or pegs located inside it. The resulting turbulent and chaotic movement produces high shear and impact forces, breaking the bonds between particles, reducing the size of the agglomerates and returning the particles (pigments and fillers) to their initial size. This process achieves a <\/span>perfect and homogeneous distribution<\/b> of the particles in the base liquid.<\/span><\/p>\n

With <\/span>O+B wet grinding equipment<\/b>, it is possible to optimise the dispersion and grinding process according to the characteristics of the product to be manufactured and the type of production developed in the factory. In this way, high-quality fineness, transparency, gloss and pigment development can be achieved in manufacturing processes.<\/span><\/p>\n

What factors affect the wet grinding process?<\/h2>\n

To make the wet grinding process more efficient, it is important to achieve the smallest possible agglomerate size. Hence the importance of a good pre-dispersion process to separate these agglomerates as much as possible.<\/span><\/p>\n

Other <\/span>factors to be considered to achieve a better wet grinding process include:<\/span><\/p>\n
