AI Technical Summary
Existing sand mills have a limited grinding effect in epoxy resin production, requiring a certain amount of time to achieve the desired material crushing effect, and the crushing speed is slow with uneven particle size.
It adopts a combination design of multiple sets of crushing hammers and grinding media, combined with grinding columns and screening structures, to improve grinding efficiency and uniformity through multi-stage grinding and screening, and is equipped with a cooling system to prevent temperature rise.
It significantly improves the grinding effect and uniformity of epoxy resin raw materials, shortens grinding time, increases production efficiency, and ensures safety and product quality.
