For small crushers,, opt for compact small double-roll crusher. Their advantages include a compact structure, minimal wear parts, energy efficiency, environmental friendliness, and controllable particle size, making them ideal for small to medium-scale operations. Select models based on material hardness and output requirements (e.g., 2PG400×400 or 2PG1060), prioritizing wear-resistant designs (such as rollers with welded overlay) and manufacturer after-sales service. Conduct on-site inspections of equipment performance and make decisions based on budget and long-term costs.
Small Crusher
When selecting a small double-roll crusher for sand production, comprehensively consider output requirements, material characteristics, equipment performance, and maintenance costs. Key points and recommended solutions are as follows:
1. Define Production Requirements
Output Matching
Small double-roll sand crushers typically offer outputs of 2-50 tons per hour. For 5-10 tons/hour, consider models 2PG400×250 or 2PG400×400; for 20-50 tons/hour, evaluate 2PG610×400 or 2PG1060.
Example: 2PG400×250 processes river pebbles at 2-10 tons/hour with 2-8mm output, suitable for small sand plants.
Material Characteristics
Hardness: Suitable for materials with compressive strength ≤250MPa (e.g., pebbles, limestone). High-hardness materials require wear-resistant roller liners.
Moisture & Stickiness: Wet or sticky materials can be processed by adding scraper anti-stick rollers.
2. Equipment Performance & Configuration
Core Parameters
Feed Size: Small units typically ≤30mm (e.g., 2PG400×400), while larger models can handle up to 50mm.
Output Adjustment: Hydraulic or spring-loaded roll gap adjustment (typically 2-15mm) controls final particle size.
Wear Resistance and Energy Consumption
Prioritize high-chromium alloy roll linings (lifespan 6 months to 5 years), such as Huashengming Heavy Industry’s weld overlay roll surfaces.
Energy-saving design: Certain models (e.g., hydraulic double-roll crushers) consume 30% less energy than traditional equipment.
3. Maintenance and Cost
Maintenance Ease
Simple-structure models (e.g., 2PG400×250) facilitate repairs; hydraulic models support automatic adjustment, reducing manual intervention.
Wear part replacement cost: Though wear-resistant roll liners have higher unit prices, their extended lifespan results in lower overall costs.
Return on Investment
Small-scale equipment ranges from tens of thousands to over one hundred thousand yuan; compare manufacturer quotes.
Long-term benefits: Low-failure-rate, low-power-consumption equipment (e.g., the 2PG1060 with 50 tons per hour capacity) reduces operational costs.
