# Bench Crusher for Mining and Assay Applications

## Introduction
In the mining and mineral processing industry, sample preparation is a critical step to ensure accurate assay results. A bench crusher is a compact, robust machine designed to crush small quantities of ore or rock samples efficiently. These crushers are commonly used in laboratories, assay offices, and small-scale mining operations to reduce sample sizes before further analysis.

## What Is a Bench Crusher?
A bench crusher (also known as a laboratory jaw crusher or benchtop crusher) is a manually or mechanically operated device that crushes materials between two hardened steel jaws. It is typically mounted on a workbench or stand, making it ideal for controlled crushing in confined spaces.

Key Features:
- Compact design – Fits easily on lab benches or field setups.
- Adjustable gap setting – Allows control over particle size output (typically 2–10 mm).
- Durable construction – Made from hardened steel for long-lasting performance.
- Manual or motorized operation – Some models use hand cranks, while others are electric-powered.

## Applications in Mining & Assaying
1. Sample Preparation for Assay Testing
- Crushes ore samples into fine particles for fire assay, ICP-MS, or XRF analysis.
- Ensures homogeneity before splitting and pulverizing.

2. Exploration & Small-Scale Mining
- Used by prospectors and geologists to test mineral content in field samples.
- Helps determine ore grade before large-scale processing.

3. Quality Control in Processing Plants
- Verifies feed material consistency before milling or leaching operations.

## Advantages of Using a Bench Crusher
✔ Precision Crushing: Delivers uniform particle sizes for reliable assay results.
✔ Cost-Effective: Eliminates the need for large industrial crushers in lab settings.
✔ Portability: Lightweight models are ideal for remote exploration sites.
✔ Low Maintenance: Simple mechanical design reduces downtime and repair costs.

## Choosing the Right Bench Crusher
When selecting a bench crusher, consider:
- Sample hardness (e.g., soft limestone vs hard quartz).
- Desired
