The Effect of Glue Solution on Manufacturing of White Clay Pigment

Abstract

The effect of the glue solution were investigated in the grinding and elutriation process for manufacturing of White clay pigment. In grinding process, glue solution decreased the production of a too fine powder and enhanced the degree of sorting of ground pigments. The grinding performance and limit are generally influenced by the frictional force. Therefore, the friction force was measured in accordance with the grinding conditions. As a result of measuring a friction force, when using glue solution it showed the lowest friction. Finally, the application of glue solution in grinding process is believed to enhance the degree of sorting of ground pigments by reducing frictional force. In elutriation process, the application of glue solution enabled the screening of larger particles in the same conditions by reducing the sedimentation velocity. This result is due to increase in the viscosity of the glue solution according to glue concentration. As a result, the application of glue solution in elutriation process is though to enlarges the range of the selectable particle size and to enable the segmentation of the particles.
