Zhongyu Dingli 300 TPH Bluestone Crushing Production Line — Customized for High-Quality Aggregate
Engineered for bluestone (basalt/limestone variant) processing, this 300 TPH production line leverages bluestone's moderate hardness (Mohs 3–6) and easy-crushing nature to deliver a simplified, cost-efficient crushing circuit. It resolves four core industry pain points — inefficient crushing, high investment cost, uneven particle shape, and unstable output — through a flexible dual-scheme design and closed-loop precision screening.
Project Scale
Application Scenario Bluestone quarries, commercial aggregate plants, highway and bridge construction, urban development, and landscape projects — where moderate-hardness stone needs efficient, multi-spec aggregate output with minimal footprint.
Core Pain Points Solved
| Pain Point | Our Solution |
|---|---|
| High investment for multi-stage crushing | PCZ1512 Heavy Hammer Crusher: "crushing + shaping" in one step, investment cost reduced 30% |
| Uneven finished particle shape | High-manganese steel linings + optional Impact Crusher shaping, cubic output ≥85% |
| Unstable capacity at 300 TPH | DLZG1548 Feeder + closed-loop screening, ≤3% fluctuation, 24/7 operation |
| Large floor space requirement | Vertical stacked screen layout (3-layer upper + 2-layer lower), footprint reduced 25% |
Solution Highlights
Bluestone-Specific One-Step or Two-Stage Crushing with Precision Screening
Raw bluestone is uniformly fed via a DLZG1548 Vibrating Feeder into the primary crusher. In the cost-saving scheme, a single PCZ1512 Heavy Hammer Crusher performs crushing and shaping in one step. In the high-stability scheme, a Jaw Crusher handles primary reduction followed by an Impact Crusher for secondary shaping. Crushed material enters vertical stacked Vibrating Screens (3-layer upper + 2-layer lower) for precision grading into 05, 12, and 13 specifications. Oversized material returns automatically to the crusher for reprocessing, while fine material can be directed to an optional DLZSJ Sand Maker for manufactured sand — forming a fully closed-loop, zero-waste circuit.

Project Feature The PCZ1512 Heavy Hammer Crusher was positioned at the optimal location based on original site conditions. The vibrating screens adopt a vertical stacked structure — 3-layer mesh screen on the upper level and 2-layer mesh screen below — effectively minimizing floor space occupation while maintaining full multi-spec grading capability.
Customer Feedback
"The single hammer crusher scheme cut our equipment investment by nearly 30%. The vertical stacked screen design saved significant space on our constrained site, and we achieved stable 300 TPH from day one." — Quarry Operations Manager
Q1: Which crushing scheme should I choose — the single hammer crusher or the jaw + impact combination? Choose based on your bluestone hardness and budget. For softer bluestone (Mohs 3–4, typical limestone variant), the PCZ1512 Heavy Hammer Crusher achieves "crushing + shaping" in one step, reducing equipment investment by 30% and shortening the production line. For harder bluestone (Mohs 5–6, basalt variant), the Jaw Crusher + Impact Crusher combination provides more stable shaping and better particle uniformity. Zhongyu Dingli's EPC team analyzes your raw material samples and recommends the optimal scheme before design.
Q2: How does the vertical stacked screen layout save floor space? Traditional 300 TPH lines require two or more vibrating screens placed side by side. Our design stacks a 3-layer screen on the upper level and a 2-layer screen directly below it in a vertical configuration. This structure maintains full multi-spec grading capability (05, 12, 13 aggregates simultaneously) while reducing the screening area footprint by approximately 25–28% — critical for projects with limited land availability or existing site constraints.
Q3: Can this line produce manufactured sand as well as aggregates? Yes. The line supports an optional DLZSJ Double-Rotor Sand Maker module. Fine material (0–5mm) from the vibrating screens can be directed to the Sand Maker for deep processing, producing manufactured sand that meets commercial concrete gradation standards. This modular addition requires no major line restructuring — simply an additional conveyor branch and the Sand Maker unit, making it easy to upgrade from aggregate-only to aggregate + sand dual-output.
