Hydraulic Crusher Machine, also known as hydraulic double-roll crushers,represent an upgraded version of traditional spring-loaded double-roll crushers, utilizing hydraulic cylinders for pressure output. While conventional spring-loaded double-roll sand makers require manual spring pressure adjustment over extended use to meet finished product specifications, hydraulic CNC double-roll crushers feature automatic pressure regulation for precise compensation. Suitable for fine crushing operations with feed sizes ≤80mm, producing finished particles ranging from 50μm to 20mm. This equipment offers convenient, efficient, and flexible operation, producing uniformly sized particles while minimizing on-site dust pollution. It delivers outstanding performance with a compact footprint, simple adjustment of crushing ratios, and reliable operation.
Hydraulic Crusher Machine
1.Hydraulic Crusher Machine

2.Working Principle
The hydraulic crusher machine utilizes two independently driven roller shafts that rotate in opposite directions to generate crushing and grinding forces. Material enters through the feed opening and falls between the rollers, where it is crushed by the opposing rollers before naturally discharging. When encountering excessively hard or uncrushable material, the rollers automatically retract via hydraulic cylinders or springs, increasing the gap between them. allowing the hard or uncrushable material to pass through unharmed. This mechanism safeguards the machine from damage. The pressure of the hydraulic cylinders or springs can be adjusted to control the final product’s particle size.
3.Performance Advantages
1. High Crushing Ratio and Strong Production Capacity
Utilizing the compression crushing principle, it achieves a high crushing ratio and is suitable for coarse, medium, and fine crushing of high-hardness materials such as coal, limestone, and slag. The machine operates smoothly with robust production capacity.
2. More Crushing, Less Grinding with Excellent Product Shape
By reducing feed particle size and improving the pulverization characteristics of feed material, it achieves greater crushing and less grinding, enhancing production efficiency. The finished product is fine and of high quality.
3. Long Service Life and Low Operating Costs
The roller shells are made of high-yield wear-resistant materials, featuring strong impact resistance and high wear resistance. Material loss during crushing is minimal, with low failure rates. This reduces subsequent maintenance and upkeep costs, resulting in low operating expenses and a long service life.
