Modern jaw crushers are pivotal in sand and aggregate processing, offering high crushing ratios (up to 6:1) and capacities ranging from 50–1,600 t/h. Leading manufacturers integrate advanced features like hydraulic adjustment (e.g., CSS range: 50–200mm) and wear-resistant manganese steel jaws (18% Mn content) to extend service life by 30%.
A typical production line includes:
– Primary Jaw Crusher: PE-1200×1500 model (Feed size: 1,020mm, Output: 400–800 t/h)
– Secondary Cone Crusher: HP300 (Max feed: 230mm, CSS: 16–45mm)
– VSI Sand Maker: Rotor speed: 1,500–2,500 rpm, Output: 60–520 t/h
– Vibrating Screen: 3–4 deck designs (Screening efficiency: ≥90%)
| Model | Feed Size (mm) | Capacity (t/h) | Power (kW) | Weight (t) |

| JC180 | 1,200 | 350–500 | 180 | 28.9 |
Q1: How to reduce jaw plate wear?
*A:* Use pre-screening to remove fines, maintain proper CSS, and rotate plates periodically.
Q2: Ideal moisture content for VSI sand shaping?
*A:* Below 3% for optimal particle shape; add dust collectors if exceeding 5%.
