What machine makes gunpowder?

Gunpowder is typically produced using a combination of industrial mixers and granulators. The process involves carefully blending the key ingredients—potassium nitrate, charcoal, and sulfur—before granulating the mixture into uniform particles. Specialized equipment, such as ball mills, is often used to grind the components and ensure a consistent mixture. Safety measures are critical throughout the process due to the explosive nature of the materials involved.
