The Hydraulic Double-Roll Sand Making Machine is a high-efficiency crushing and sand-making device designed for medium and fine crushing of various ores and rocks. By combining advanced hydraulic control technology with a double-roll crushing structure, this machine delivers uniform particle size, high output efficiency, and excellent operational stability, making it ideal for modern sand and aggregate production lines.

Working Principle

The hydraulic double-roll sand making machine operates using two high-strength alloy rollers rotating in opposite directions. Materials are fed into the crushing chamber and crushed through extrusion and shearing forces between the rollers.

The hydraulic system automatically adjusts the roller gap according to material hardness and size, ensuring consistent output granularity. When encountering uncrushable materials, the hydraulic system releases pressure automatically, protecting the machine and extending its service life.
