1. Main Types and Models

Double Roll Crusher (Core Product)

Small Models: 250×250, 250×400, 400×400, 610×400, hourly output 2-20 tons, price 16,500-68,000 RMB.
Features: Dual-roll compression crushing, adjustable output size 1-3mm, suitable for medium-low hardness materials like limestone and coal gangue.
Medium Models: 750×500, 800×600, hourly output 20-50 tons, price 50,000-120,000 RMB.
Large Hydraulic Models: 1500×1000, 1800×1000, hourly output 50-450 tons, price 380,000-660,000 yuan.
Impact Crusher

Applications: Fine crushing operations, processing high-moisture or medium-hard materials (e.g., limestone, shale), with flexible adjustable output particle size.
Hammer Crusher

Features: Single-stage crushing, suitable for materials with low compressive strength (e.g., gypsum, slag), but wear resistance is inferior to double-roll crushers.

2. Core Advantages

Economy and Durability

Low Investment Cost: Small double-roll crushers start at just ¥16,500, with unit energy consumption 15%-20% lower than hammer crushers.
Patented Wear-Resistant Rollers: High-chromium manganese steel + rare metal composite material, lifespan exceeding 2 years (processing over 30,000 tons).
Flexible Adaptability

Precise particle size control: Stepless adjustment of roll gap from 1-20mm, supporting fine sand (1-3mm) or aggregate (5-40mm) production.
Wet material processing capability: Anti-clogging structure handles materials with 15% moisture content, such as muddy gold ore or coal.
Intelligent Operation & Easy Maintenance

Hydraulic models: Support one-button start/stop and remote monitoring, reducing manual intervention.
Modular design: Minimal wear parts; routine maintenance requires only bearing temperature and hydraulic pressure checks.

3. Typical Application Scenarios

Sand and Aggregate Production
Manufactured Sand Preparation: Double-roll crushers produce well-rounded particle shapes with low over-crushing rates, suitable for high-standard concrete aggregates.
Gold Mining
Pre-crushing: Small double-roll crushers process ore under 125mm, producing 10-40mm output for efficient leaching.
Construction Waste Recycling
Concrete Fine Crushing: The 250×400 model produces 1-3mm recycled aggregate, boosting recycling rates by 40%.
