Jaw Crusher 400 x 250: Specifications and Applications
The jaw crusher 400 x 250 refers to a compact crushing machine with a feed opening size of 400 mm (width) by 250 mm (depth). This model is typically classified as a small to medium-sized crusher, suitable for primary crushing in laboratories, small-scale mining, or recycling operations.
Key Specifications
- Feed Opening: 400 mm x 250 mm (16" x 10")
- Max Feed Size: ~350 mm (depending on jaw design)
- Output Size: Adjustable, typically ranging from 20 mm to 80 mm
- Power Requirement: Usually driven by a 15–30 kW (20–40 HP) electric motor
- Weight: Approximately 2,500–3,500 kg (varies by manufacturer)
Design and Functionality
The jaw crusher operates on the principle of compressive force, where two manganese jaw plates—one fixed and one movable—crush material fed into the chamber. The movable jaw exerts pressure, breaking down rocks, concrete, or other hard materials into smaller fragments. .jpg)
Common Applications
- Laboratory Use: Ideal for sample preparation in geology and metallurgy due to its precise size reduction capability.
- Small-Scale Mining: Used for processing gold ore, quartz, or other minerals where portability is key.
- Recycling: Crushes concrete, bricks, and demolition waste for reuse in construction projects.
Advantages of the 400 x 250 Model
- Compact Size: Fits easily in confined spaces or mobile setups.
- Low Operating Costs: Requires minimal maintenance compared to larger units.
- Versatility: Handles a variety of materials, including hard rock and recycled aggregates.
Manufacturer Variations
