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`.

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.
