Gravitation blasting is basically an injector blasting system, however, with the difference that the blasting medium bunker is located above the blasting gun. So the blasting medium drops into the blasting gun as a result of its specific weight and is then accelerated in the blasting jet by the compressed air feed. Gravitation blasting is in terms of output in between the injector blasting system and the pressure tank blast system.
Uniform, impact-free blasting medium discharge from the blasting jet at low blasting pressure of, for example, less than 1 bar. Gravitation blasting is usually used for automated processes.
