🧪 HPGR Pressure Zone (2D): Throughput, Force & Product Size

This 2D companion reads the nip zone of a High Pressure Grinding Roll as a plan you can tune rather than a scene you orbit: operating gap, specific press force, roll speed and feed size drive the same throughput, specific-energy, power and product-size relations a real HPGR circuit is set up with, while a stream of ore particles visibly compresses and darkens as it crosses the pressure zone between the two counter-rotating rolls and exits as a thinner, finer "flake" below. Push the press force up and watch product size drop while power draw climbs — the same trade-off a plant metallurgist balances when tuning throughput against grind fineness.
