To meet the demands of a 1000mm feed capacity and a high throughput of 400t/h, Baichy Heavy Industry recommends a three-stage closed-circuit crushing process: a PEW European-style jaw crusher, an HST single-cylinder hydraulic cone crusher, and an HPT multi-cylinder hydraulic cone crusher. This configuration is specifically designed for the highly abrasive nature of granite, aiming to produce high-grade aggregates (0-5/5-12/12-20mm) with full shape and reasonable gradation through laminated crushing technology, while reducing the cost of wear parts by more than 15% per ton.

I. Equipment Specification
| Stage | Core Equipment | Model Recommendation | Core Parameters/Functions |
| Primary Crushing | European-style Jaw Crusher | PEW1100 (equivalent to C125) | Feed opening 1100×1200mm; Capacity 300-450t/h; V-shaped crushing chamber ensures more stable material gripping. |
| Secondary Crushing | Single-cylinder hydraulic cone crusher | CH250 (coarse chamber type) | Constant crushing chamber design; large throughput, rapidly reducing 300mm material to below 100mm. |
| Tertiary Crushing | Multi-cylinder hydraulic cone crusher | HP300 (fine chamber type) × 2 | Layered crushing principle; increases cubic content in 5-20mm aggregate, controlling needle-like and flaky content < 8%. |
| Screening System | Heavy-duty vibrating screen | 4YZK2460 | Four-layer arrangement; precise grading, processing capacity adapted to 400t/h full-line flow. |
II. Core Advantages of the Solution (Technical Edges)
1. European Jaw Crusher Technology: Tackling the "Hardest Nuts"
The PEW1100 uses an integral cast steel bearing housing optimized by finite element analysis, capable of withstanding the enormous impact generated by granite crushing. Compared to traditional jaw crushers, its wedge-type discharge port adjustment system reduces downtime adjustment time by 80%.
2. Cascaded Cone Crusher: Balancing Efficiency and Particle Shape
CH Single-Cylinder Crusher: As a secondary crusher, its simple structure and large throughput make it a pioneer in processing 300mm-sized materials.
HP Multi-Cylinder Crusher: As a finishing stage, its combination of high speed and stroke generates powerful lamination crushing, transforming 12-20mm aggregates from "flaky materials" into "Cubes" conforming to high-performance concrete standards.
3. Targeting the Wear-Resistant Nature of Granite
For the highly abrasive nature of granite (high SiO₂ content), our cone crusher liners are made of Mn18Cr2 special alloy.
Expected Life: Jaw plates are recommended for replacement at 1200-1500 hours; cone liners are recommended for replacement at 1800-2000 hours (depending on the specific rock's Mohs hardness and moisture content).
III. Digital Factory Data (Operation Matrix)
Total Installed Power: Approximately 850 - 950 kW.
Suggested Footprint: Approximately 65m × 35m (including belt conveyor return system).
Delivery Time: Standard model 35-45 working days; customized belt frame and steel structure should be started 2 weeks in advance.
Frequently Asked Questions
Q: Why are two HPT300 units recommended for the tertiary crushing stage instead of one larger unit?
A: The dual-unit configuration provides greater production flexibility. During equipment maintenance or market demand fluctuations (e.g., only a small amount of stone powder is needed), a single unit can be operated or its chamber shape adjusted, ensuring the production line does not completely stop and allowing for more precise control of the 0-5mm finished product proportion.
Q: How to control the needle-like and flaky content in the finished aggregate?
A: The key lies in "full-cavity crushing" and the "lamination principle". Through the multi-cylinder hydraulic extrusion of the HPT series, materials are crushed within the chamber rather than simply split, thus significantly improving particle shape.
Q: How does Bailey Heavy Industries assist with logistics and installation?
A: We offer modular delivery (skid-mounted parts) to reduce on-site welding work. All key equipment (jaw crusher, cone crusher) uses an integrated chassis, and with the cooperation of Bailey's on-site engineers, the entire production line can be commissioned with materials within 15-20 days after delivery.
