Granite, basalt, river pebbles, these hard stone crushing sand making, the choice of crushing equipment is the key. With its unique design and hydraulic system, hydraulic roll crusher shows significant advantages in the field of hard stone crushing, the following is a detailed analysis of its core advantages:
hydraulic roll crusher
1. Hydraulic roll crusher structure design and performance advantages
Compact structure, convenient operation
The structure of the equipment is simple, occupies little space, and is easy to install and maintain. The design of internal dustproof plate effectively reduces the dust leakage, and the working noise is low (≤85dB), which improves the working environment.
Efficient crushing and even discharging
Double rollers rotate in the same direction to achieve efficient crushing of materials through extrusion, shearing and kneading, and the finished product has uniform particle size (adjustable range of 1-35mm), which meets the demand for high-standard construction sand.
Wear-resistant and long life
The roller body adopts high-strength wear-resistant alloy (e.g. chrome-molybdenum alloy), which extends the service life by more than 30% compared with the traditional equipment, and the roller body is free to be replaced for life.
2. Core advantages of hydraulic system
Intelligent adjustment and stability
The hydraulic system automatically adjusts the roller spacing and pressure, adapts to the change of material hardness in real time, and ensures the stability of the particle size of the discharged material (digital display, no need for repeated manual adjustment).
Overload protection and safety
Overload protection is automatically activated when encountering hard objects (e.g. metal iron parts) to prevent equipment damage; the hydraulic accumulator maintains stable system pressure (working pressure of 6-8MPa) to avoid sudden failure.
Significant energy saving and consumption reduction
All-hydraulic drive saves 50%-80% energy compared with mechanical transmission; the system dynamically adjusts the power to reduce no-load energy consumption; the unit power consumption is only 0.8-1.2 degrees/tonne.
3. Environmental protection and maintenance cost advantage
Low dust and noise
Sealed structure combined with dustproof plate design reduces dust leakage by 70%; noise control meets environmental standards (≤80dB).
Low maintenance cost
Low failure rate of the hydraulic system, few transmission parts, daily maintenance only need to check the hydraulic oil and lubrication regularly; lifelong free replacement of the roller body design significantly reduce long-term costs.
4. Wide range of application scenarios
Wide material adaptability
It can handle materials with compressive strength ≤250MPa and moisture content ≤35%, including river pebbles, granite, limestone, construction waste, etc.
Flexible matching of production capacity
The models cover 20-180 tonnes per hour (e.g. 2PG1200×1200 with a capacity of 100 tonnes per hour), and support customised design (e.g. double-stage no-screen-bottom model to handle high moisture and viscous materials).
