Abstract
An ice blasting system comprising a hopper to receive bulk ice and a rotary crusher disposed inside the hopper, the rotary crusher having rotary crusher arms that cooperate with anvils to produce crushed ice from the bulk ice. The system includes a rotary feeder mechanism disposed below the hopper, the rotary feeder mechanism having a rotor that includes ice-receiving pockets for receiving the crushed ice. The rotor rotates against an airtight seal block and delivers the crushed ice into a high-pressure airstream passing through the rotary feeder mechanism to thereby entrain the crushed ice into the high-pressure airstream whereby the ice-entrained airstream subsequently exits the ice blasting system through an outlet.
Claims23
An ice blasting system comprising:
- a hopper to receive bulk ice, the hopper including a V-shaped upper hopper portion and a semicircular lower hopper portion;
- a rotary crusher disposed inside the hopper, the rotary crusher having a plurality of rotary crusher arms that rotate within the semicircular lower hopper portion, the rotary crusher also having a plurality of anvils that cooperate with the rotary crusher arms to produce crushed ice from the bulk ice, wherein the rotary crusher arms have serrations forming rotary crusher teeth and wherein the anvils also have anvil teeth;
- and
- a rotary feeder mechanism disposed below the hopper, the rotary feeder mechanism having a rotor that includes ice-receiving pockets for receiving the crushed ice, wherein the rotor rotates against an airtight seal block and delivers the crushed ice into a high-pressure airstream passing through the rotary feeder mechanism to thereby entrain the crushed ice into the high-pressure airstream whereby the ice-entrained airstream subsequently exits the ice blasting system through an outlet.

An ice blasting system comprising:
- a hopper to receive bulk ice;
- a V-shaped crusher having crushing teeth to crush the bulk ice to make crushed ice;
- a rotary feeder mechanism disposed below the hopper, the rotary feeder mechanism having a rotor that includes ice-receiving pockets for receiving the crushed ice, wherein the rotor rotates against an airtight seal block and delivers the crushed ice into a high-pressure airstream passing through the rotary feeder mechanism to thereby entrain the crushed ice into the high-pressure airstream whereby the ice-entrained airstream subsequently exits the ice blasting system through an outlet;
- and
- a comb-block attached to an ice piston to push the crushed ice into the ice-receiving pockets.
