Hard Rock Grinding - Pick Force and grinding pattern

A video demonstration of what's meant by 'pick force'. You can see and almost feel the rock shatter as each tooth of the grinder head rotates into contact with the surface.
Among the options for mitigating solid rock obstacles like this, project managers chose Hard Rock's rotary grinder rather than the more traditional breakers. The rotary grinder removes just the material needed without over large laybacks, noise, truck traffic and waste.
Alpine rock, volcanics, caliche, concrete, quarrying, roadheaders, tunnelling, cave excavation, trenching. You name it, this versatile tool does the job.
