1. Core Product Line and Technical Advantages

Wear-Resistant and Durable Design

Roll Shell/Hammer Material: Made from high-chromium manganese steel alloy (containing ≥12% chromium), offering three times the wear resistance and a service life exceeding 8,000 hours.

Screenless Structure: Dual-stage crushers (e.g., SCF series) feature a screenless design, preventing blockages in wet or sticky materials and maintaining efficient crushing even with moisture content ≤15%.

Intelligent Control and Precise Particle Size

Hydraulic Adjustment System: Roll crushers (such as the 2PGY series) support infinite adjustment of the roll gap from 1–50 mm, with an output particle size error of ≤±2 mm and a cubic particle ratio of >85%.

Automated Operation: Equipped with an intelligent control system, it can be operated by one person, with an over-crushing rate of <5%, reducing labour costs.

Environmental Protection and Low Energy Consumption

Closed crushing chamber + dust collection system, reducing dust by 60% and noise levels below 85 dB.

Energy consumption is only 0.5–0.8 kWh/tonne, achieving energy savings of 30%–50% compared to traditional crushers.

Flexible Adaptability

Some models support tyre/track chassis (e.g., PE series jaw crushers), with relocation time ≤2 hours, suitable for temporary quarries and construction sites.

Note:
Economical small-scale model: Two-stage crusher (SCF series) priced as low as 14,000 yuan, suitable for projects with limited budgets.

High-spec intelligent model: Hydraulic double-roll crusher (2PGY series) with remote monitoring capability, suitable for scenarios with high environmental protection requirements.

3. Typical application scenarios and cases

Construction waste recycling

Equipment configuration: SCF800×600 two-stage crusher + vibrating screen
Results: Concrete blocks are crushed into 0–50 mm recycled aggregate with a utilization rate of ≥90% and a 40% reduction in costs.

River Pebble Sand Making

Equipment Configuration: 2PGY750×500 Double-Tooth Roller Crusher + Sand Washer
Results: Output particle size of 2–8 mm with over 85% cubic particles, suitable for replacing natural sand in C30 concrete.

Shale/Sandstone Processing

Equipment Configuration: 2PGY800×600 Hydraulic Double-Roller Crusher
Effect: Hunan customer feedback reports an hourly output of 100–300 tonnes, uniform particle size, and a 30% reduction in maintenance costs.

4. Purchase Recommendations and Pitfall Avoidance Guide

Select based on requirements

Hard rock crushing (granite > 150 MPa): Select jaw crusher (PE series) for primary crushing + cone crusher for secondary crushing.
Medium to low hardness materials (limestone, shale): Hydraulic double-roll crusher (2PGY series) balances efficiency and particle size control.
Wet and sticky materials: Two-stage crusher (SCF series) with anti-blocking design for optimal performance.

Factory Inspection Focus

Material Testing: Request a chromium content report for the roller lining (≥12% is acceptable) to avoid misrepresentation of wear resistance.
Testing verification: Conduct material tests to evaluate crushing performance on different hardness materials (e.g., granite vs. limestone).

Avoid common pitfalls

Misleading capacity claims: Require third-party testing reports (e.g., SCF800×800 rated at 30 tonnes/hour must be verified through actual testing).
After-sales terms: Ensure warranty period ≥1 year, spare parts supply ≤72 hours, and 24-hour technical response.

5. After-sales service and price reference

Full-cycle service

Pre-sales: Free scheme design, trial operation with materials (verified on site at the Gongyi factory).
After-sales: Solutions provided within 8 hours, on-site arrival within 24 hours, lifetime technical support.
