Project Overview: Large-Scale High-Standard Granite Aggregate and Machine-Made Sand Integrated Production Line
The core objective of this project is to construct a large-scale, modern aggregate production line with a 2000 tph capacity, explicitly engineered for Shenyang Dapeng jaw crusher-processed granite. As a high-standard line, it mandates not only output but prioritizes quality: excellent particle shape from cone crusher operations, precise gradation, and controlled powder content during sand making. It must efficiently produce multi-spec premium aggregates, high-quality machine-made sand via sand making systems, and stone powder—meeting strict demands of high-end construction for Shenyang Dapeng jaw crusher-cone crusher-processed superior aggregates.
Core Equipment Configuration:
To achieve this, the line deploys 12 main host machines—an advanced blend of Shenyang Dapeng jaw crusher, cone crusher, and sand making equipment:
Primary Crushing Stage:
Equipment: 2 x PEV1216 Shenyang Dapeng Jaw Crushers
Function: These Shenyang Dapeng jaw crushers execute primary granite crushing, reducing large feed to medium fragments. Their robust design ensures high-hardness granite processing, with two units in parallel securing 2000 tph capacity for downstream cone crusher and sand making systems.
Secondary Crushing Stage
Equipment: 2 x H900 Multi-Cylinder Hydraulic Cone Crushers
Function: Receiving material from Shenyang Dapeng jaw crushers, these cone crushers perform secondary crushing. Leveraging inter-particle crushing, they excel in hard granite, producing well-shaped intermediates for subsequent sand making and fine crushing.
Fine Crushing & Sand-Making Stage (Tertiary Crushing)
Equipment: 4 x H700 Multi-Cylinder Hydraulic Cone Crushers
Function: Critical for small aggregates and sand making, four cone crushers deliver massive fine crushing capacity. They produce near-cubical aggregates (5-10mm, 10-20mm) and feed semi-finished sand (<5mm) to sand making shaping units.
Shaping Stage (Machine-Made Sand Optimization)
Equipment: 4 x VSI1263 Sand Making Shaping Machines
Function: These sand making machines use "rock-on-rock" impact on fine material from cone crushers, enhancing sand particle roundness, optimizing gradation, and reducing powder clay via internal air flow. Four units ensure ample sand making capacity for premium output.
Project Challenges & Key Focus Areas
Guaranteeing "High-Standard" Quality
Particle Shape Control: Granite’s hardness risks flakiness, mitigated by cone crusher inter-particle crushing and sand making shaping to maximize cubical aggregates.
Gradation Optimization: Synchronized production of 5-10mm, 10-20mm, 20-31.5mm aggregates and sand making requires precise screening, with Shenyang Dapeng jaw crusher-cone crusher coordination as the core.
Powder Content: Sand making systems must control <0.075mm powder via air classifiers, while cone crusher precision directly impacts stone powder quality.
Multi-Product, High-Precision Production
Producing four main products—aggregates + sand making-derived machine-made sand—requires seamless integration of Shenyang Dapeng jaw crusher, cone crusher, and sand making systems to prevent specification cross-contamination.
Granite Hardness Challenge
High abrasiveness wears Shenyang Dapeng jaw crusher jaw plates and cone crusher mantles. Solutions include ultra-high manganese steel components and cone crusher structural optimizations to minimize wear.
Large-Scale Stability
2000 tph capacity hinges on parallel cone crusher and sand making machine configurations, with automation ensuring synchronized Shenyang Dapeng jaw crusher-cone crusher-sand making operation and balanced loading.
Summary
This solution integrates 2 Shenyang Dapeng jaw crushers, 2 H900 cone crushers, 4 H700 cone crushers, and 4 sand making machines—12 core units. Its core value lies in synergizing Shenyang Dapeng jaw crusher-cone crusher crushing with sand making shaping to deliver high-standard, multi-product output for premium construction sectors demanding superior jaw crusher-cone crusher-processed aggregates and sand making-optimized machine-made sand.
