Crusherblocks has engineered a rugged 600-ton-per-hour granite processing system in Heihe, Heilongjiang, tailored to withstand -30°C winters while producing premium aggregates for border-region highways and Trans-Siberian railway expansion projects. This Arctic-grade facility combines enclosed thermal hoppers, anti-freeze crushers, and multi-stage material optimization to conquer the unique challenges of China’s northernmost quarries.

Permafrost-Optimized Innovations

1. Winterized Primary Station

Heated Enclosed Hopper: Electrically warmed receiving bay prevents material freezing, maintaining 850mm feed capacity even at -25°C.

Slope-Adapted Layout: 6.2m elevation drop between truck ramp and jaw crusher enables gravity-assisted flow, reducing loader fuel costs by 35%.

2. Dual Pre-Screening System

Grizzly Feeder with De-Icing Bars: Vibrating grids pre-separate ≤300mm granite chunks while breaking frost-bonded materials.

Rotary Soil Screener: Removes 18% frozen clay content before crushing.

Crushing Process Breakdown

Stage 1: Primary Reduction

Heavy-Duty Jaw Crusher: Processes 850mm granite blocks into ≤300mm fragments.

Frost-Resistant Steel: Crusher liners with HB450 hardness withstand abrasive ice-rock mixtures.

Stage 2: Secondary Crushing (GP400S Cone Crushers)

Twin 315kW cone crushers with heated hydraulic systems:

Left cavity: Coarse crushing to 0-75mm

Right cavity: Closed-side adjustment maintains 51-75mm critical sizing

Stage 3: Intelligent Cold-Screening

4 Thermal Screens: Classify materials into:

0-5mm: Direct to insulated sand silos (concrete batching)

5-51mm: To VSI crusher for cubic shaping

51-75mm: Recirculated via heated conveyors to tertiary cone crusher

Stage 4: Final Shaping

Arctic VSI Crusher: Equipped with heated rotor bearings for -30°C operation.

Closed-Loop Recirculation: 60% recrush rate optimizes particle gradation.
