QS-4 Light Plastic Type Roller Jar Mill is a high-performance, bench-top laboratory instrument designed for the ultra-fine grinding, mixing, and homogenization of materials . Also known as a jar rolling mill or roll ball mill, this equipment is the ideal solution for R&D institutions, universities, and small-scale production facilities that require a reliable and easy-to-use milling machine. Its "light plastic type" design emphasizes a compact structure without compromising on durability or grinding efficiency, making it a preferred choice for processing a wide variety of materials from ceramic glazes to battery components
QS-4 Roller Jar Mill is widely used across various industries for sample preparation and small-batch production:
Ceramic Industry: Grinding and mixing of ceramic glazes, porcelain enamels, and clay bodies .
Battery Research: Homogenizing and grinding cathode (e.g., LiFePO₄, LiCoO₂) and anode materials for lithium-ion batteries .
Materials Science: Preparing electronic materials, magnetic materials, and metal powders .
Construction Materials: Processing cement, slag, and new building materials for quality control .
Chemical & Pharmaceutical: Mixing and fine-grinding of chemical reagents, pigments, and pharmaceutical ingredients .
