The double-roll crusher (also known as the twin-roll crusher) is fully capable of serving as a Minerals Industry Stones Crusher.
Minerals Industry Stones Crusher
1. Working Principle
The double-roll crusher achieves material fragmentation by applying compressive and shear forces through two counter-rotating rolls, featuring the following core capabilities:
Feed Size: Typically 15%–40% of roller diameter; common equipment handles ore ≤80mm
Discharge Size: Adjustable 2–30mm with high precision and minimal over-crushing
Processing Capacity: 5–500 tons/hour (depending on model)
2. Core Advantages
Precise Particle Size Control
Roll gap adjustable via shims (0.3–40mm), low over-grinding rate (minimal dust), high product uniformity (e.g., manufactured sand yield >90%).
Energy Efficiency & Low Pollution
When integrated into grinding systems, it boosts production by 30%-40% while reducing overall energy consumption by 20%-30%.
The compression process generates minimal heat. Ceramic roll surfaces prevent metal contamination and preserve mineral properties (e.g., coal coking characteristics).
Simple Structure and Easy Maintenance
Modular design reduces roll skin replacement time by 50%. Hydraulic models support one-button gap adjustment.
3. Typical Mining Applications
Coal Industry
Direct crushing of raw coal containing gangue without pre-removal, simplifying coal preparation processes. Output particle size uniformly controllable between 2–30mm.
Non-metallic Mineral Fine Crushing
Limestone/Dolomite: Pre-crushes cement clinker to 3–30mm, boosting mill output by 40–70%.
Artificial Sand Production: Processes river pebbles and construction waste into sand (0.3–5mm) with >90% yield and rounded particle shape.
Medium-Fine Crushing of Metal Ores
Processes sintered ore lumps or pre-crushed hematite, producing 0.5–5mm output while reducing ball mill energy consumption by 30%.
Industrial Waste Recycling
Crushing steel slag, coal gangue, etc., with 15–20% lower energy consumption and compliance with environmental standards.
