Background

In the vast field of plastics processing, plastic grinding mills play a vital role. They efficiently grind raw plastics—such as PE, PP, PA, ABS, and PVC—into fine powders tailored to meet diverse application requirements.

Masterbatch processing

In the production of colorants, color uniformity and stability are crucial, and the core depends on the uniform dispersion of pigments in the carrier resin. For this reason, the fineness of plastic powder needs to be precisely controlled at 20-30 mesh: being too coarse can easily cause color spots and lines; Increasing costs and reunion risks through detailed regulations. Our grinding machine ensures strict particle size standards through precision grinding and intelligent control, while achieving preliminary uniform mixing of pigments and resins. The color masterbatch produced by this device is well dispersed during mixing, avoiding color deviation, reducing energy consumption and equipment loss, and helping plastic products achieve stable and high-quality color performance.

Rotational molding processing

The rotational molding process has specific requirements for the fineness of plastic powder: the powder needs to be evenly spread and filled in the mold to ensure uniform wall thickness and smooth surface of the product, with an ideal fineness of 30-40 mesh. Our grinding machine produces powders with precise fineness within this range, with good flowability and bulk density. During rotational molding, it can evenly adhere to the inner wall of the mold, helping to produce high-quality products while avoiding problems such as flying too fine and uneven distribution too coarse. It saves materials, is environmentally friendly, and improves production efficiency and product quality.

PVC processing

In the production of PVC products, different products have specific requirements for the fineness of plastic powder: PVC pipes require a fineness of 20-30 mesh to promote sufficient mixing of resin and additives, and the internal structure is dense during extrusion to improve strength, toughness, and corrosion resistance, reduce bubbles and cracks, and extend service life; PVC profiles (such as door and window frames) need 40-50 mesh fineness to ensure smooth surface and accurate size after extrusion. They are mixed with additives to form a stable structure and enhance rigidity, toughness and aging resistance. Our grinding machine can accurately grind to the corresponding fineness, adapt to different needs, and help produce high-quality pipes and profiles that meet the strict standards of building doors and windows.
