High-Reduction Crushing for Laboratory Sample Preparation
The Alsto FJC300 Fine Jaw Crusher is a dual-action jaw crusher designed for laboratory sample preparation, delivering a high reduction ratio and sample throughput. It is engineered to reduce lump ore, achieving a product size of approximately 85% of the sample at ≤2 mm in a single step under controlled conditions.
With a maximum feed size of 70 mm, the FJC300 can reduce the need for pre-crushing, helping to streamline sample preparation workflows and minimise opportunities for contamination.
Key Benefits
- High size reduction: Achieves approximately 85% of the product at ≤2 mm under specified test conditions.
- Dual-action crushing: Designed to deliver effective size reduction in a single step.
- Reduced pre-crushing requirements: Accepts lump samples up to 70 mm, helping simplify sample preparation.
- Reduced contamination risk: Minimises additional handling and processing steps.
- Robust construction: Built for demanding laboratory sample preparation applications.
- Straightforward maintenance: Designed to support ease of maintenance and extended service life.
- Optional sample division: Can be supplied with an optional Rotary Sample Divider to support representative sample splitting.
Key Features
- 275 × 85 mm jaw inlet.
- Maximum feed size of 70 mm for lump material.
- Dual-action jaw crushing mechanism.
- Two dust extraction connection points.
- Dust extraction flow requirement of 150 L/s.
- 5.5 kW, three-phase motor.
- Optional Rotary Sample Divider.
Applications
The Alsto FJC300 is suitable for laboratory sample preparation where lump ore must be reduced to a finer particle size for subsequent testing and analysis. Its single-step reduction capability can help laboratories streamline sample preparation and reduce manual handling.
Performance note: Outputs have been achieved under controlled conditions. Actual performance depends on machine settings, feed rate, material type, hardness, crushability, shape and feed volume.
