Granite Chips & Decorative Natural Stone Aggregates | Industrial B2B Bulk Supply
Granite Chips are processed industrial-grade mineral aggregates manufactured from selected natural granite ore through multi-stage crushing, screening, and dedusting. Designed for integration into architectural coatings, resin systems, and exterior construction assemblies, these chips provide a uniform mineral substrate with controlled particle morphology. Dengjian New Materials operates automated crushing and classification lines in Dongtai, Jiangsu, supplying consistent bulk quantities matching strict international building material tolerances.

Key Features
Controlled Particle Grading:
Screened through multi-deck vibrating separators to maintain strict particle size distribution and minimize oversized or undersized fractions.
Natural Mineral Composition:
Sourced from dense, crystalline granite, offering inherent resistance to UV degradation, thermal expansion, and weathering.
Low Fines Content:
Industrial dedusting processes reduce micro-dust adherence, ensuring cleaner mixing with epoxy, acrylic binders, and cementitious mortars.
Batch Uniformity:
Controlled raw material blending limits optical and physical variations across successive production runs.

Aqueous Extract Method |
Production begins with raw granite block selection based on mineral purity and chromatic stability. The raw stone undergoes primary jaw crushing followed by secondary impact crushing to preserve angular, interlocking particle geometry rather than flaky fragments. Material then passes through a multi-stage closed-circuit screening system utilizing high-frequency vibrating screens. Air-aspirated separation extracts fine dust particles, followed by optional thermal rotary drying to control moisture levels prior to packaging.
Applications
Real Stone Paint & Texture Coatings:
Acts as the solid aggregate base in exterior wall architectural coatings, providing mechanical strength and natural stone aesthetics.
Landscaping & Exterior Architecture:
Applied in surface dressing for pedestrian walkways, resin-bound gravel pathways, and architectural precast concrete panels.
Epoxy & Resin Flooring:
Utilized in decorative, anti-slip multi-layer industrial floor systems and broadcast flake systems.
Waterproofing & Protective Mortars:
Embedded in cementitious and polymer-modified protective layers for enhanced impact resistance.
Manufacturing & Quality Control
Dengjian New Materials operates out of a dedicated facility within the Qindong New Materials and Equipment Industrial Park. Production execution follows strict quality protocols:
Sieve Analysis Control:
Random samples are pulled every 2 hours from production lines to verify particle size distribution curves against target specifications.
Moisture and Dust Monitoring:
Laboratory testing measures residual moisture and dust content to ensure compatibility with solvent-free and water-based resin binders.
Traceability:
Each pallet is labeled with a production batch code linked to raw material source logs and processing parameters.
Color / Size / Packaging Options
Color Profiles:
Natural Grey, Solid Black, Pink, White, and Custom Blended Multi-Color Granules.
Size Gradients:
Fine powder, micro-granules (1-3mm), medium chips (3-5mm), and coarse aggregates (up to 20mm).
Packaging Configurations:
25 kg moisture-resistant polyethylene (PE) lined woven bags.
1,000 kg heavy-duty industrial bulk FIBC bags (sling bags) with bottom discharge spouts.
Custom palletization with stretch-wrapping and weather-protective hoods for ocean freight.
Bulk Supply & OEM Customization
Supply Capacity:
Continuous production lines support steady monthly output volumes for large-scale distributors and manufacturing plants.
OEM / Private Label:
Custom packaging printing, specific particle size distribution (PSD) blending, and customized color ratio matching based on client-provided physical color chips.
Logistics Support:
Direct container loading from factory yard to port (Shanghai/Ningbo), complete with fumigation-free pallets and export compliance documentation.
