## Description

This MCP server provides specialized engineering tools for Semi-Autogenous Grinding (SAG) mill design. It allows AI agents to determine physical mill dimensions using `calculate_mill_dimensions`, estimate electrical motor power with `calculate_power_requirements`, and optimize grinding media with `estimate_ball_charge`. Additionally, it can evaluate the necessity of a pebble crushing circuit via `evaluate_pebble_circuit` based on ore hardness and feed size.

## Tools

### calculate_mill_dimensions
Determines the necessary physical size of the SAG mill

### calculate_power_requirements
Estimates the electrical power required to drive the mill

### estimate_ball_charge
Calculates the optimal amount of steel grinding media needed

### evaluate_pebble_circuit
Determines if a pebble crushing circuit is required

## Prompt Examples

**Prompt:** 
```
What are the dimensions for a SAG mill with 500 tph throughput, BWi of 15, feed size of 150mm, and target product size of 2mm?
```

**Response:** 
```
The required SAG mill dimensions are a diameter of 6.5 meters and a length of 8.0 meters, providing a total volume of 265.4 cubic meters.
```

**Prompt:** 
```
Calculate the power requirements for a mill with 7m diameter, 9m length, 15% ball charge, and 60% ore volume.
```

**Response:** 
```
The estimated motor power is 4250 kW with a torque of 185000 Nm.
```

**Prompt:** 
```
Do I need a pebble crusher for an ore with BWi of 18, feed size of 120mm, and product size of 3mm if a crusher is available?
```

**Response:** 
```
Yes, based on the high Bond Work Index and size reduction requirements, a pebble crushing circuit is required to maintain efficiency.
```

## Frequently Asked Questions

**How do I calculate the mill size?**
Use the `calculate_mill_dimensions` tool by providing the target throughput, Bond Work Index (BWi), feed size, and desired product size.

**Can I estimate the power needed for the motor?**
Yes, the `calculate_power_requirements` tool estimates motor power and torque based on the mill's diameter, length, and charge volumes.

**How is the ball charge determined?**
The `estimate_ball_charge` tool calculates the required steel media mass and volume percentage using the mill diameter, ore Abrasion Index (Ai), and throughput.
