How can the challenges of producing sand from hard, fractured rock be overcome?
Here is a 400-ton-per-hour basalt sand-making production line for a client in Xiaogan, Hubei, which successfully processes raw material into high-quality manufactured sand and crushed stone. We break down this solution for you across three aspects: raw material processing capacity, core equipment, and the advantages of the complete production line!
I. Raw Materials and Production Capacity
Material processed: Hard rock (high hardness, high abrasiveness)
Capacity: 400 t/h
Output: Manufactured sand + crushed stone
Production Process: The stages of crushing, screening, sand washing, and dewatering are seamlessly integrated.Hard rock is efficiently crushed to the desired particle size using a jaw crusher,
a cone crusher, and a sand-making machine.It then undergoes precise classification via a vibrating screen to separate stone from sand; the sand passes through a sand washer and a dewatering screen,ultimately yielding clean, well-graded finished sand.
II. Process Flow and Advantages
This production line is equipped with the following core equipment, each optimized for the characteristics of hard rock.

1. PE600x900 Jaw Crusher (Primary Crushing)
1.1. Large feed opening and high crushing force; specifically designed for primary crushing of hard rock
1.2. Deep crushing chamber; high reduction ratio and high output
1.3. Compact structure, stable operation, and easy maintenance

2. PY1400 Compound Cone Crusher (Secondary Crushing)
2.1. Operates on the principle of inter-particle (lamination) crushing, yielding good product particle shape and low content of elongated or flaky particles.
2.2. Features overload protection and a hydraulic chamber-clearing system; automatically retracts upon encountering uncrushable material.
2.3. Wear parts offer a long service life; particularly suitable for the secondary and tertiary crushing of high-hardness materials.

3. TLS1563 New Sand-Making Machine (Fine Crushing)
3.1. Dual crushing mode (rock-on-rock and rock-on-iron) produces well-shaped, rounded aggregate.
3.2. High crushing efficiency; sand yield increased by over 20%.
3.3. Hydraulic cover opening allows for quick and convenient maintenance and hammer replacement.

4. 2YK3080 Vibrating Screen (Grading/Sizing)
4.1. Double-layer screen design enables the simultaneous separation of various material sizes, such as sand, small stones, and medium-sized stones.
4.2. Large screening area (3m wide × 8m long) ensures high processing capacity and prevents screen clogging.
4.3. Adjustable vibration force achieves screening efficiency exceeding 95%.
4.4. Screens are easy to replace, accommodating different requirements for finished product particle sizes.
III. Project Benefits: Resource Transformation, Significant Returns
Upon completion and commissioning, the production line will achieve the following:
Annual Output: Approximately 1 million tons of manufactured sand and crushed stone
Resource Utilization: Converts local high-hardness basaltic rock into high-value-added manufactured sand and premium crushed stone, turning waste into a valuable resource and solving the challenge of processing hard rock
Economic Benefits: Dual-product output with simultaneous sales of sand and stone, significantly boosting profitability
Social Benefits: Meets the demand for sand in local and regional infrastructure projects, reduces natural sand extraction, and protects the ecological environment
