## Description

This MCP server provides technical engineering tools for High Pressure Grinding Rolls (HPGR) circuit design. It allows users to calculate essential equipment parameters such as roll dimensions using `get_roll_dimensions`, determine necessary pressing forces with `calculate_operating_pressure`, and evaluate material flow efficiency via `estimate_specific_throughput`. Additionally, it helps predict maintenance needs using `predict_roll_lifespan` based on ore abrasiveness and pressure.

## Tools

### calculate_operating_pressure
Finds the necessary pressing force to achieve the desired product size

### estimate_specific_throughput
Calculates the efficiency of the material flow through the rolls

### get_roll_dimensions
Determines the physical size of the rolls required to meet a target throughput

### predict_roll_lifespan
Estimates how long the rolls will last before requiring maintenance based on wear

## Prompt Examples

**Prompt:** 
```
What roll dimensions do I need for a throughput of 500 tph and an ore hardness of 15?
```

**Response:** 
```
The required roll diameter is 2.5 meters and the roll width is 1.8 meters.
```

**Prompt:** 
```
Calculate the operating pressure for an ore with hardness 12, target size 5mm, and 5% moisture.
```

**Response:** 
```
The specific pressure required is 3.2 N/mm² with a total force of 450 kN.
```

**Prompt:** 
```
Estimate the lifespan for an abrasive ore (index 8) at 3 N/mm² pressure and 400 tph throughput.
```

**Response:** 
```
The estimated operating life is 4,500 hours with a wear rate of 0.02 mm per hour.
```

## Frequently Asked Questions

**How do I calculate the required roll size?**
Use the `get_roll_dimensions` tool by providing the target throughput and the ore hardness.

**Can I predict how long the rolls will last?**
Yes, the `predict_roll_lifespan` tool estimates operating hours based on ore abrasiveness and operating pressure.

**What inputs are needed for pressure calculations?**
You need to provide the ore hardness, the target product size, and the moisture content to `calculate_operating_pressure`.
