3. Performance Advantages
High Efficiency & Energy Savings
Dual-motor drive design reduces energy consumption by 45% for equivalent output;
Low over-crushing rate with uniform particle size, ideal for high-hardness materials (e.g., river pebbles, granite).
Exceptional Durability
Roll shells utilize high-chromium manganese steel wear-resistant material, ensuring a service life exceeding 2 years (patent pending);
Integrated hydraulic spring design with overload protection minimizes wear part consumption.
Flexible Adjustment
Hydraulic system regulates roll gap for precise output particle size control (adjustable 1-10mm).
4. Application Scenarios & Materials
Suitable Materials: River pebbles, granite, basalt, limestone, coal gangue, construction waste, etc.
Application Fields:
Sand production in aggregate plants (fine crushing), medium crushing in mines, chemical raw material pulverization;
Construction waste recycling (e.g., crushing asphalt milled material).
