Rebound Hammer Test: What You Need to Know - Gilson Co.
Pushing the test hammer's piston against the surface of hardened concrete loads a spring mechanism until it trips and releases a hammer mass. The mass strikes the piston, which impacts the concrete with a defined amount of energy. As the hammer mass bounces back, a sliding indicator records the rebound number (R-value) on a simple linear scale.

Understanding the Basic Working Principle of Hammer Mills
Inside the grinding housing, the raw material is reduced not only by the repeated blows of the hammer but by the walls of the grinding chamber and the impact of particle on particle. Specially designed metal screens or steel grates classify the material and discharges it once it's been reduced to its desired size.
