Scarifying machines apply a cutting wheel to the concrete surface. EDCO's exclusive 6-shaft cutting drum flails the surface, leaving a clean, textured or roughened finish. Scarifiers are also referred to as planers, milling machines, rotary cutters or simply surface-preparation machines. These versatile machines have various styles of interchangeable cutter assemblies that can be used for cleaning, grinding and light or heavy milling. Production rates range from 350 to 1,500 square feet per hour (dependent on machine size and horsepower) for a 1/8-inch removal depth of 3,500 PSI concrete.
