Dry wet blast media blasting system
A wet media blasting system with a water injection system that provides more uniform distribution of the water, air and media components for achieving better application of the mixture while minimizing the amount of water required to contain and minimize or eliminate airborne particulate matter such as dust produced during the blasting operation. By more thoroughly mixing the water into the abrasive/water mix, the amount of water required is reduced. The abrasive feed is placed and shaped to optimize spray coverage and minimize abrasive flow into injection space thus mitigating water nozzle clogs. The abrasive flow is shaped as it is released from the metering valve in order to tighten the abrasive flow before it enters into the blast air stream. The shaped and tightened abrasive flow is maintained at the lower portion of the blast air stream. This positions the abrasive flow in optimum placement for spray wetting the abrasive as it flows into and through the nozzle. This also mitigates nozzle clogging by directing most of the abrasive flow away from the water spray nozzle port. |

Processing apparatus
A grinding apparatus has a hermetically sealed chamber defined by a portion of a holding surface which extends radially outwardly from a wafer, an outer wall surface of a first annular packing, a lower surface of a plate, and an inner wall surface of a second annular packing.

A mixture outflow path is formed in a lower portion of the housing. The mixing space is formed to allow the drive rotor and the driven rotors to rotate and to regulate the positions of the drive rotor and the driven rotors. Meshing the drive rotor with the driven rotors allows the driven rotors to rotate opposite to the rotating direction of the drive rotor accompanying the rotation of the drive rotor while the lower ends of the driven rotors are located above a bottom portion of the mixing space and the upper ends of the driven rotors are located below the lower surface of the lid body. |

Parallel stirring blade
A stirring blade includes a first member having a first flat surface and a second member having a second flat surface, wherein the stirring blade is rotatable about a rotational axis in a state where the first and second flat surfaces are opposed to each other and spaced by a first distance across the rotational axis. When the stirring blade is rotated about the rotational axis with the first and second flat surfaces at least partially immersed in an object to be stirred, the object to be stirred having entered between the first and second flat surfaces is discharged in a direction away from the rotational axis by a centrifugal force and, simultaneously, the object to be stirred is sucked into and between the first and second flat surfaces from a direction along the rotational axis. |
