Pump Solutions for Abrasive Mining Applications
was made to internally create a brand new pump—one that could effectively pump the concrete through the machine and also tolerate the material’s abrasive properties. This revolutionary cement pump worked so well, it spawned new research and development at Bredel that ultimately yielded longer hose

Discoveries during Development of the next generation Ultrahigh Pressure Water Jetting Machines
ultrahigh pressure water with added garnet abrasives in the water jet will be the best solution. The so called abrasive watercutting. Because Speedclean ultrahigh pressure cleaners have the same capacities as professionell water cutting machines, we will develop additional equipment for abrasive water

Comparing cleanroom wipers with a dry abrasion resistance test
, for example leachable from the wipers by various solvents. Tests designed to measure particles released by abrasive interaction between wipers and a surface, however, have rarely been reported. Exceptions to this are the stress-strain studies by Mattina and Paley, and Oathout and Mattina, which showed

An Investigation of Ceria-Based Slurries Exhibiting Reverse-Prestonian Behavior (.pdf)
New slurry formulations have been developed for polishing oxide in both shallow trench isolation (STI) and inner layer dielectric (ILD) CMP processes. These formulations use cerium oxide as the abrasive, since the industry requires a higher performance from these slurries for both

Lasers Dismantling Concrete Structures
of the complexities involved in the decontamination and decommissioning of nuclear facilities. In the laser centric approach there is no requirement of added media, like abrasive chemicals to assist the process, significantly reducing the volume of secondary waste to be disposed off. In addition
