Understanding Crusher Types and Their Output Size Ranges

Different crushers are engineered for specific size-reduction missions. Knowing their design principles helps match machinery to your desired stone dimensions.

• Щековые дробилки: Идеально подходит для первичного дробления, these machines handle boulders up to 1200mm (like those processed by the C6X200 model with a 1500×2000mm feed opening) and reduce them to 175-300mm coarse aggregates. Their fixed and moving jaws create a compressive “chewing” motion perfect for rugged initial size reduction.
• Конусные дробилки: For secondary crushing, конусные дробилки (like the HPT100) refine 40–100mm input into 3–20mm outputs. Adjustable settings let operators fine-tune for products like 5mm road base or 20mm drainage stone.
• Hammer Crushers: In gold mining operations, hammer mills crush ≤50mm ore into ultra-fine 0.1–12mm particles—critical for mineral liberation. Models like the 300×500 hammer mill use manganese steel beaters to force material through size-control screens.
• Ударные дробилки: Vertical shaft impact crushers (VSI sand makers), such as those producing ≤5mm sand, fracture stone through high-speed collisions. They excel at creating cubicle grains for concrete—with some models accepting 700mm feed stones.

Key Factors That Determine Crushed Stone Dimensions

Beyond crusher type, four variables dictate your final product sizing:

1. Feed Size Limitations
   Every crusher has maximum feed dimensions (например, BF60.1 crusher buckets accept rocks ≤510mm). Oversized material causes jams and wear, while undersized feed reduces efficiency. Always match primary crusher output to your secondary unit’s input tolerance.
2. Crushing Chamber Geometry
   Cone crushers like the HPT series use bowl-shaped chambers where stone compresses between mantles and concaves. Narrower chambers yield finer output—like the HPT100’s 3–20mm product versus HST100’s 4–22mm.
3. Screen or Grate Configuration
   Hammer mills and impact crushers rely on replaceable screens/grates. A 14mm screen produces matchstick-sized aggregate, while a 22mm screen yields chunkier 5–8cm stones.
4. Регулируемые настройки
   Hydraulic systems in modern cone crushers enable real-time adjustments.

How to Control and Adjust Your Crusher’s Product Size?

Optimizing output isn’t guesswork. Use these proven strategies:

• Cone Crusher Adjustments: Rotate the bowl thread assembly on HPT-series models to decrease/increase the closed-side setting (CSS). A 15mm CSS on a HPT600 yields ~5mm aggregate, while 25mm produces 10–15mm stone.
• Screen Swaps: For hammer mills, switching from a 14mm to 22mm screen increases output size from 3–5cm to 5–8cm—boosting throughput by 200% (from 3tph to 10tph).
• RPM Tuning: Higher rotor speeds in ударные дробилки intensify collisions, creating finer particles. Reduce speed for coarser output when processing limestone for landscaping.
• Мониторинг износа: As manganese jaws wear, output size drifts upward. Measure discharge weekly—a 10% increase in average size signals replacement time.

Pro Tip: Always test crusher settings with sample material first. I once saw a quarry lose a week’s production by assuming “15мм” settings matched their previous crusher’s calibration.

Real-World Applications for Different Crushed Stone Sizes

Your target application dictates the ideal crusher output. Consider these matches:

• 3–5mm “Artificial Sand”: VSI дробилки create spherical grains that replace river sand in high-strength concrete mixes. SBM’s 200tph VSI6X impact crusher achieves this with 0–500mm limestone.
• 10–20mm Drainage Aggregates: Cone crushers produce angular stones that interlock—preventing pipe movement in infrastructure projects.
• 50–90mm Road Base: Primary jaw outputs compact tightly under asphalt. Mobile units like SBM Crusher’s K3 allow on-site crushing of demolition concrete into 60–90mm recycled base.
• 100–150mm Armor Stone: For seawalls or erosion barriers, jaw crushers with open settings process blasted rock into large, durable blocks.

Matching Your Crusher to Desired Stone Sizes

Ultimately, answering “Какие размеры измельченного камня может производить дробилка?” requires analyzing your feed material, target products, and volume needs. Small gold operations thrive with 1.5tph hammer mills making 0.1mm particles, while quarries use 500tph cone crushers for 20mm aggregate.

My golden rule? Prioritize adjustability. Crushers with hydraulic CSS control (like PYB cones) or screen-swap systems future-proof your operation against shifting market demands. After all, the ability to switch from making 5mm sand to 30mm ballast—without new equipment—separates profitable plants from stagnant ones.
