Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of paint sand mill, especially to a paint sand mill for paint production. BACKGROUND

[0002] When the paint sand mill is used for paint production, a paint sand mill for paint production is often used, which is a device specially used for grinding and dispersing solid particles in paint. Through the relative movement between the high-speed rotating sand mill disc and the fixed container, the pigments and fillers in the paint are effectively refined and uniformly dispersed by using grinding media (such as glass beads, zirconia beads, etc.). The use of this sand mill can bring many benefits. First, it can significantly improve the fineness and uniformity of the paint, ensuring a smooth and delicate paint film surface. Second, through efficient grinding and dispersion, the production cycle of the paint can be shortened, and the production efficiency can be improved. In addition, the sand mill can also improve the flowability and stability of the paint, and enhance the quality and performance of the final product. Therefore, in the paint production process, it is essential to use a professional paint sand mill.

[0003] The paint sand mill usually includes inputting pre-mixed paint raw materials (such as pigments, resins, and solvents) into the sand mill, effectively grinding and dispersing pigment particles by high-speed rotating grinding media (such as glass beads or zirconium silicate beads) to achieve the required fineness and uniformity, and then discharging the ground paint through the discharge port to complete the entire production process.

[0004] Some paint sand mill devices for paint production in the prior art have many problems when in operation. The most prominent problem is the inability to accurately dose the paint. In actual production, too much or too little dosage will have a serious impact on the grinding effect of the paint. If the dosage is too much, the materials in the sand mill will be too crowded, resulting in insufficient contact and collision between the grinding media and the materials, which will further affect the grinding effect of the paint and make it difficult to ensure product quality. If the dosage is too little, it will cause the equipment to idle, wasting energy and reducing production efficiency, which will increase production costs. Therefore, a paint sand mill for paint production is proposed to solve the above problems. INVENTION CONTENTS
