Abstract
The blades of a rotary blasting machine are removably mounted on a rotor bracket in a spaced relationship with the bracket outwardly from a point of contact at the inner extremity of the blade-bracket junction. Preferably, the space diverges outwardly, and an inner portion of the blade hooks over the bracket to resist centrifugal force acting on the blade, and also seal the junction against ingress of abrasive particles.
Claims4
A blasting machine having a rotor including a rotatable shaft and a plate mounted on said shaft in a plane normal to the axis of rotation of said shaft, and also including at least one bracket secured to said plate and a blade detachably secured to said bracket in a position adjacent a radial plane containing said axis, said machine also including feeding means adapted to supply abrasive material to the central portion of said rotor for engagement with said blade, wherein the improvement comprises:
- projection means on at least one of said bracket and said blade extending from the face of said one of said bracket and blade opposite the other thereof and establishing a space between said opposite faces.
