ABRASIVE CUTTING FLUIDS

摘要

To form an abrasive cutting fluid, two sizesof abrasive grit are mixed together with a high concentration of flocculent and water to form a thick slurry which is fed by a pump (3) into a pressure vessel (4). Water from feed point (7) passes through a flocculent retention chamber (8) and flocculent is added at high dosage. The flocculated water is fed by pump (6) through manifold (13) and slurry from pressure vessel (4) is added to establish a laminar flow through flexible hose (14) which leads to a nozzle (11). The fluid exits the nozzle (11) as a high-pressure, abrasive cutting jet. The laminar flow may reduce internal wear in the flexible hose (14).
