Jaw crusher

As the first stage of material reduction, jaw crushers, with their robust structure, reliable performance, and wide applicability, have become core crushing equipment in industries such as mining, building materials, and metallurgy. Jiangsu Haijian Co., Ltd. is a professional jaw crusher manufacturer and company. We provide specialized equipment for cement production, industrial solid waste incineration, and mining and metallurgy applications. Our jaw crushers are capable of processing a variety of hard materials with a compressive strength of ≤320 MPa (such as granite, basalt, and iron ore). Using the compression crushing principle, they reduce bulk materials to a particle size suitable for subsequent processing steps. They are essential primary crushing equipment in modern production lines.

Jaw crushers perform key tasks in industrial production:
Primary crushing: Crushes mined ore (up to 1500mm) to 100-350mm, providing qualified feed for subsequent secondary and tertiary crushing equipment.
Hard material handling: Specially designed for coarse crushing of hard materials such as granite (compressive strength 250MPa) and iron ore (compressive strength 300MPa).
Process simplification: The deep chamber design achieves a high crushing ratio (typically 10:1), reduces the number of crushing stages, and reduces system complexity.

Typical application scenarios:
Mining: Primary crushing of metallic and non-metallic ores
Building materials production: Coarse crushing of limestone and construction waste
Road construction: Preparation of roadbed aggregates
Metallurgy: Crushing and recycling blast furnace slag

Key selection points:
Select jaw plate material (manganese steel/alloy steel/ceramic composite) based on material hardness.
When handling sticky and wet materials, the discharge opening should be enlarged to avoid blockage.
For mining applications, a heavy-duty frame (steel plate thickness ≥ 50mm) is recommended.
