System and method for selectively filtering abrasive particles for a waterjet cutter

A system for selectively filtering abrasive particles for a cutting machine, the system comprising:

• multiple interchangeable screens, each screen defined by a perimeter region and forming multiple openings defined by a shape and dimension, each opening being defined a unique shape and dimension, the screens being operable to filter at least one foreign debris from multiple abrasive particles, the screens further being operable to segregate different sizes and dimensions of the abrasive particles;
• a sieve subassembly comprising a containment ring and a main base that are welded together;
• a two-piece split clamp ring, the two-piece split clamp ring and the main base sandwiching the perimeter region of the screens,
• whereby multiple screens interchangeably join the sieve subassembly;
• a pneumatic variable speed motor operably connected to the sieve subassembly, the pneumatic variable speed motor being operable to vibrate the screens at variable speeds;
• an air inlet in fluid communication with the pneumatic variable speed motor, the air inlet operable to enable discharge of air flow into the pneumatic variable speed motor;
• and
• an air valve operatively joined with the air inlet, the air valve configured to regulate the air flow through the air inlet,
• whereby the air valve regulates the speed and intensity of vibrations to the screens.
