1. Product Types and Features
Double Roll Crusher (Flagship Small Equipment)
Working Principle: Dual-roll compression crushing, suitable for medium-fine crushing of medium-to-low hardness materials (limestone, coal gangue, shale, etc.).
Core Advantages:
Energy-Efficient & Durable: Roll surfaces utilize high-chromium manganese steel wear-resistant material, ensuring a service life exceeding 2 years; energy consumption per unit output is lower than traditional hammer crushers.
Flexible Adjustment: Hydraulic system regulates discharge particle size (adjustable between 1–3mm), accommodating diverse finished product requirements.
Simple Maintenance: Streamlined structure with minimal wear parts reduces long-term operational and maintenance costs.
Smart Upgrades: Select models support remote monitoring and intelligent adjustment for enhanced operational convenience.
Impact Crusher
Ideal for mobile operations (e.g., highway, hydropower projects), excels at processing high-moisture or medium-hard materials (e.g., limestone). Produces well-shaped final products with low over-crushing rates.
Advantages: Strong anti-clogging capability, wide discharge size adjustment range, low maintenance costs.
2. Small Double Roll Crusher Models and Parameters
Below is a comparison of mainstream small models:
| Model | Production Capacity (tons/hour) | Power (kW) | Weight (tons) | Applications |
|---|---|---|---|---|
| 2PGT400×250 | 2–12 | 15–22 | ≈2.5 | Small-scale sand plants, early-stage startups |
| 2PGT400×400 | 5–20 | 18–30 | ≈3.0 | Small-to-medium-sized aggregate processing lines |
| 2PGT610×400 | 10–20 | 30–45 | ≈4.5 | Medium-scale sand and gravel pre-treatment |
| 250×400（Roller Mill） | 5–10 | 50 | ≈5.0 | Coal mines, fine grinding operations |
3. Application Scenarios and Materials
Material Range: River pebbles, limestone, granite, coal gangue, slag, gypsum, and other medium-to-low hardness materials.
Typical Applications:
– Sand preparation pre-processing for small-to-medium sand and gravel plants;
– Recycling of construction waste/stone offcuts (sand-head material);
– Fine crushing of coal and chemical raw materials.
