Huashengming Small Electric Rock Crusher Featuring dual-roll (precision particle size), jaw (large-block coarse crushing), and dual-stage (wet material specialist) core technologies, it covers applications including sand and gravel fine crushing, construction waste recycling, and tailings processing:
Small Electric Rock Crusher
1. Core Product Series and Model Specifications
Double-roll Crusher (Flagship Model)
Achieves precise sand production through dual-roll compression (adjustable particle size 1-50mm), with under-crushing rate <10%. Suitable for fine crushing of medium-hard rock.
| Model | Processing Capacity (t/h) | Output Particle Size (mm) | Motor Power (kW) | Application Scenarios |
| 2PGT400×250 | 2–10 | 1–3 | 7.5×2 | Construction Waste Recycling, Gold Mine Test Mining |
| 2PGT400×400 | 5–12 | 1–5 | 11×2 | Small-Scale Sand Plant, Limestone Sand Production |
| 2PGT610×400 | 5–20 | 2–8 | 15×2 | Coal Crushing, Quartzite Fine Crushing |
Technical Highlights:
Roll shells feature a high-chromium manganese steel + rare metal composite layer (triple-layer structure), with a lifespan exceeding 2 years (processing capacity > 30,000 tons);
Spring-adjustable roll gap (±1mm precision) enables granularity fine-tuning.
Jaw Crusher (Preferred for Primary Crushing)
Processes large rock blocks (feed ≤340mm), featuring simple structure and low maintenance costs.
| Model | Processing Capacity (t/h) | Maximum Feed Size (mm) | Motor Power (kW) |
| PE-150×250 | 1.2–3.5 | 125 | 5.5 |
| PE-250×750 | 5 | 210 | 15 |
Suitable Applications: Laboratory coarse crushing, small-scale quarries (e.g., primary crushing in gold mining)
Double-Shaft Impact Crusher (Specialized for Wet/Sticky Materials)
Dual-rotor design without screen bottom, supports direct crushing of materials with moisture content ≤15%, near-zero clogging rate.
| Model | 处理能力 (t/h) | Output Particle Size (mm) | Motor Power (kW) |
| 600×600 | 20–30 | ≤3 | 22+22 |
| 800×600 | 35–55 | ≤3 | 45+55 |
Advantages: Crushes high-moisture coal gangue and shale into fine sand in a single pass, eliminating the need for pretreatment.
2. Core Performance Comparison
| Specifications | Double-roll type | Jaw | Two-stage |
|---|---|---|---|
| Crushing Principle | Double-roll compression + shearing | Jaw plates reciprocating compression | Dual rotor impact + material self-collision |
| Output Particle Size | 1–50mm (adjustable) | 10–300mm (primary crushing) | ≤3mm (fine crushing) |
| Wet Material Adaptability | Medium (moisture content ≤10%) | Poor | Excellent (moisture content ≤15%) |
| Energy Consumption | 0.8–1.0kWh/ton (30% energy savings) | Moderate | Low (15–20% savings compared to traditional equipment) |
| Maintenance Costs | Roll skin lifespan >2 years | Jaw plate lifespan >2 years | Hammer replacement every 1–2 years |
