The double-roll sand-making machine is an upgraded version of the conventional spring-loaded double-roll crusher, utilizing hydraulic cylinders for pressure output.

Older spring-loaded models require manual spring pressure adjustment after prolonged use to meet finished product specifications,

whereas the Dou Shi hydraulic double-roll sand-making machine features automatic pressure regulation with precise compensation.

Suitable for fine crushing operations with feed sizes under 80mm and finished product sizes ranging from 50μm to 20mm. It offers more convenient, efficient,

and flexible operation, produces uniformly sized particles, minimizes on-site dust pollution, delivers excellent performance, requires minimal floor space,

allows easy adjustment of the crushing ratio, and operates reliably.
