Zhongyu Dingli 2M TPA Granite Manufactured Sand Production Line — Professional Hard Rock Sand Processing
This 2 million tons per annum granite manufactured sand line is a full integrated solution for high-efficiency hard rock sand processing, delivering stable large-scale output through a scientifically configured Cone-VSI closed-loop crushing circuit. Granite's extreme hardness (Mohs 6–7) demands specialized equipment and process design — this line addresses the core challenges of hard rock sand making: rapid wear, poor particle shape, high energy consumption, and unstable fine sand gradation.
Project Scale
Application Scenario Granite quarries, commercial manufactured sand plants, and large infrastructure projects (highways, bridges, high-rise buildings) where hard-rock fine sand meeting precise gradation specifications is required for high-strength concrete and mortar production.
Core Pain Points Solved
| Pain Point | Our Solution |
|---|---|
| Rapid wear on granite (Mohs 6–7) | Cone Crusher primary + VSI "stone-on-stone" secondary, reducing metal-to-rock contact |
| Poor fine sand particle shape | VSI shaping technology producing cubic sand with low needle content |
| Unstable fine sand gradation (0.7–2.2 mm) | DL3YKZ3070 precision multi-stage screening + closed-loop return |
| High moisture in finished sand | Sand washing + dewatering circuit, final moisture 5–7% |
Solution Highlights
Granite Cone-VSI Closed-Loop Crushing with Washing & Dewatering
Raw granite (8–10 cm) is fed via a Vibrating Feeder into a Cone Crusher for primary crushing, reducing particle size to ≤5 cm. Material then enters a Vertical Shaft Impact Crusher (VSI) for secondary crushing and shaping. Crushed sand is classified by a DL3YKZ3070 Vibrating Screen — qualified fine sand (0.7–1.5 mm and 1.6–2.2 mm) proceeds to the Sand Washing and Dewatering process, while unqualified material is conveyed back to the Cone Crusher for re-crushing. After washing and dewatering, finished sand with moisture content of 5–7% is transported by conveyor belts to the finished product stockyard — forming a fully closed-loop, zero-waste production circuit.

Project Feature The production line processes 8–10 cm granite raw material through a precisely controlled two-stage crushing circuit. The Cone Crusher reduces input to ≤5 cm, and the VSI Crusher performs secondary shaping with controlled impact velocity. The DL3YKZ3070 Vibrating Screen separates dual-spec fine sand with high precision, and the closed-loop return circuit ensures every ton of granite is processed to specification — achieving zero waste and consistent product quality at 2M TPA scale.
Q1: Why use a Cone Crusher for primary crushing instead of a Jaw Crusher on granite? Granite's hardness (Mohs 6–7) requires controlled, laminated crushing to avoid excessive fine generation and equipment wear. The Cone Crusher delivers inter-particle compressive crushing — granite fragments crush each other under pressure rather than against metal surfaces — which reduces wear part consumption by 40% compared to Jaw Crushers on hard rock, and produces more uniform intermediate particle size (≤5 cm) for the downstream VSI shaping stage.
Q2: How does the line achieve precise dual-spec fine sand grading (0.7–1.5 mm and 1.6–2.2 mm)? The DL3YKZ3070 Vibrating Screen is a 3-deck precision screening unit specifically configured with mesh sizes calibrated for the two target fine sand specifications. After VSI shaping, material enters the screen where the upper deck extracts the 1.6–2.2 mm fraction and the lower deck captures the 0.7–1.5 mm fraction. Material outside both ranges is automatically returned via conveyor to the Cone Crusher for re-crushing — ensuring that every output ton meets the exact specification required for high-strength concrete and industrial mortar applications.
Q3: What is the environmental investment and how does it ensure green compliance? The project allocates 1.2 million yuan specifically for environmental protection infrastructure. This covers pulse dust collectors on all crushing and screening equipment, a closed workshop structure enclosing the entire production line, a water circulation system for sand washing with ≥90% reuse rate, and atomizing sprinkler systems for dust suppression at material transfer points. Together, these measures achieve dust emission below national standard limits and wastewater zero discharge — ensuring full compliance for long-term operation permits.
