Technical Field
[0001] This application relates to the field of horizontal sand mills, and particularly to a horizontal sand mill for preparing epoxy-modified polyester back paint. Background Art
[0002] Epoxy resin paint has characteristics in terms of adhesion to metals and corrosion prevention, but is relatively weak in terms of deformability and weather resistance. It is generally used for dipping paint, back paint, and canned paint. In the process of producing epoxy resin back paint, a sand mill is usually required for treatment. A horizontal sand mill uses a material pump to transport the solid-liquid mixture after being stirred and dispersed and wetted by a mixer into the cylinder. The material and the grinding medium in the cylinder are stirred by a high-speed rotating disperser, so that the solid particles in the material and the grinding medium rub against each other to achieve the purpose of accelerating the grinding of fine particles and the dispersion of aggregates.
