Sustainable solutions for waterjet operations

At the EuroBLECH show in Germany late last year, ConSus ANT presented the ConSus abrasive mixing unit, which now also enables continuous Water Abrasive Suspension (WAS) processes. In addition, the specialist for stationary waterjet cutting presented its new Abrasive Recycling Unit ARU (pictured) for energy-efficient, environmentally friendly recycling of abrasive.

The emergence of ever-new, challenging materials places high demands on users in the machining industry. ConSus ANT says that its abrasive mixing unit enables fast, precise and powerful cutting of all common materials in the continuous WAS process without any effects on the material or structure. Compared with the conventional Water Abrasive Injection System (WAIS) process, ConSus works up to three times faster and at less than half the pressure. These capabilities reduce time, energy and CO2 emissions. The WAS cutting jet consists only of water and abrasive, which ensures a significantly higher efficiency without turbulent mixing conditions, and leaves the cutting nozzle at almost twice the speed of sound.

Procuring, storing and disposing of cutting material is an important cost factor in industrial waterjet cutting. The Abrasive Recycling Unit (ARU) from ConSus ANT enables the processing and reuse of more than 100 kg of abrasive per hour with extremely low energy requirements. This capability enables users to increase the economic efficiency and sustainability of their processes significantly. The ARU is suitable for use with both WAIS and WAS processes. While WAIS requires the use of the ARU with a drying system for the recyclate, WAS allows the moist abrasive to be fed directly back into the cutting process. In conjunction with the ConSus abrasive mixing unit, a reuse rate of at least 80% of the abrasive is possible.
