Concrete Crushing 101 – How to Get Started
The first is removing and breaking up material on your jobsite into workable pieces using hydraulic breakers, pulverizers, or other demolition equipment. The second step is removing any metal from the concrete so it doesn't damage equipment or end up in your aggregate material. And the third step is using your concrete crusher to smash the ...

Silica & Noise at a Rock Crusher | Industrial Hygiene in Construction
Industrial hygiene at a surface-mine rock crushing operation is primarily 2 major hazards: 1. airborne silica dust and 2. noise. (there are many more safety hazards but I will focus on IH) Silica – this can vary due to: Â the amount of silica in the rock, weather conditions, type of equipment, if water is used, and where the miners work ...

Noise and Silica Exposures
The findings for noise and silica exposure are summarized in Table 1 by job type. For measurements using the PEL criterion, only groundsmen exceeded the PEL of 90 dBA, although crusher mechanics approached this limit with a mean of 89.1 dBA. When exposures exceed the PEL, exposures must be reduced below 90 dBA, and until …
