Hydraulic double roll crusher offer significant advantages over spring double roll crusher in terms of technical performance, operational efficiency, and long-term economic benefits. The following is a systematic analysis: 1. Core Performance Comparison Intelligent Adjustment and Precise Particle Size Control Hydraulic system dynamic adjustment: The hydraulic cylinder adjusts the roller gap in real time (precision ±0.1mm), with an output particle size error of ≤3%, ensuring uniform particle shape of the finished sand and gravel (cubic particle ratio ≥95%). Spring equipment limitations: Manual adjustment of spring tension is required, with an error of ≥10%, and frequent shutdowns are needed for adjustment after roller lining wear. Efficient overload protection and stability Hydraulic automatic avoidance: When encountering metal foreign objects or ultra-hard materials, the hydraulic system instantly increases the roller gap to expel the foreign object and automatically resets, reducing fault recovery time by 80%.>Spring passive compression: Relying solely on spring cushioning, manual cleaning and reset are required after hard objects pass through, which may cause component deformation or breakage. Significant energy savings and reduced consumption Hydraulic transmission is 20%-30% more energy-efficient than mechanical transmission, with power consumption of only 0.8-1.2 kWh/ton (spring-type: 1.2-1.8 kWh/ton).
