# Roll Crusher Capacity Calculator

### Introduction

A roll crusher is a piece of heavy-duty machinery used to crush materials into smaller pieces. It’s commonly used in mining and aggregate production. Understanding the capacity of your roll crusher is crucial for ensuring it operates efficiently. This article provides a detailed overview of how to use a roll crusher capacity calculator, the formula involved, an example calculation, FAQs, and a conclusion.

### How to Use the Roll Crusher Capacity Calculator

Using the roll crusher capacity calculator is straightforward. Follow these steps:

- Input the feed size.
- Enter the product size.
- Provide the width and diameter of the rolls.
- Input the roll speed.
- Press the “Calculate” button to get the result.

### Formula

The most accurate formula for calculating the capacity of a roll crusher is:

Q=π⋅D⋅W⋅S⋅ρ

Where:

- Q = Capacity (tons per hour)
- π = Pi (approximately 3.14159)
- D = Roll Diameter (meters)
- W = Roll Width (meters)
- S = Roll Speed (revolutions per minute)
- ρ = Bulk Density of the Material (tons per cubic meter)

### Example Solve

Let’s calculate the capacity of a roll crusher with the following specifications:

- Roll Diameter: 0.5 meters
- Roll Width: 0.2 meters
- Roll Speed: 50 RPM
- Bulk Density: 2.5 tons per cubic meter

Using the formula:

Q=3.14159⋅0.5⋅0.2⋅50⋅2.5

Q=3.14159⋅0.5⋅0.2⋅50⋅2.5

Q≈39.27 tons per hour
