Abrasive Slurry Preparation Unit for Micro Abrasive Water Jet Machining Applications

Technology: Abrasive slurry preparation unit;

Industry/Application: Micro machining applications; Heavy Machinery, Metal Fabrication, Automotive & Transportation;

Market: The global abrasive market is projected to reach at a CAGR of 5.0% during the forecast period (2024-30).

The problem statement discussed in the present invention is how to generate micro abrasive suspension jet in effective manner.
Hence, subject invention addresses the issue in efficient manner.

The claimed patent describes an apparatus for preparing a uniform mixture of abrasive particle for the generation of micro abrasive suspension jet.
The apparatus comprises of:
a slurry preparation unit for preparing a high-pressure slurry of carrier fluid and abrasive particle,
a source for pressurized carrier fluid,
a conduit to connect source of carrier fluid to an inlet of slurry preparation unit
a conduit to connect an outlet of the slurry preparation unit to cutting head;
a diamond orifice to form micro abrasive suspension jet.

An apparatus to provide a supply of abrasive particles in a carrier fluid to form a uniformly suspension of abrasive and carrier fluid.
Slurry preparation unit prevents agglomeration and settlement of abrasives in the flow circuit and also avoids clogging of orifice to enable continuous generation of micro abrasive suspension jet.
The apparatus facilitates a refill arrangement for continuous supply of abrasives into the slurry preparation unit.
