Small Stone Crusher Machine

Main crusher operator

Operating the main crusher, monitoring and pulling stuck boulders for a free flow, and taking care of maintenance work. This task involves lifting heavy parts and pulling boulders from the chute. Frequent shut down of the crusher occurs during operation and heavy parts are removed and fixed during this activity. This task is usually done as group work.

Cleaning work under the main crusher

The main crusher is cleaned at two stages. First, when quarry dust is collected during crushing from the pit below and the second to remove the falling and struck boulders from the pit below the main crusher. While collecting the dust from below the crusher, the workers are exposed to the highest and most hazardous concentrations of dust. Often women conduct this activity.
