Impact Tester

Application :

• The Impact Tester is a laboratory test machine used to determine the crushability of materials according to the method developed by F.C. Bond.

Construction :

• The Impact Tester consists of two pendulum-mounted hammers, each weighing approximately 30 lb, designed to simultaneously strike equal blows on opposite sides of each rock specimen.

Test Method :

• The crushability test is performed on ten or more representative pieces of broken stone. Each specimen must pass a 3-inch square opening and be retained on a 2-inch square opening. Using more specimens increases the reliability of the test results.

Operation & Safety :

• The impact tester is designed for operation by a single operator. In case of power loss, the magnets shut down and the impact hammers drop automatically when strained.

Ambient temperature :

• 5°C – 40°C

Atmospheric humidity :

• 85% RH

Dimensions :

• 2000 × 420 × 2180 mm

Feed size maximum :

• 76 mm

Gross weight :

• 150 kg (only machine)

Test repetition :

• At least 10, preferably 20 test runs per sample

Working principle :

• Crushing by impact of two hammers
