TITLE
Secondary crusher confined space access
ARTICLE
Traditionally, maintenance and inspection operations on the Arja horizontal impact crusher required the complete emptying of the feed hopper to allow for safe access due to the risk of material becoming dislodged and falling from above.

The aim was to make access into the crusher as safe as possible without having to empty the hopper. A swinging door in the Skako feeder was manufactured to control the flow of material into the crusher. This proved very successful as the material could be held back with the control door, effectively sealing the hopper from the crusher and had the added advantage of preventing surges in the crusher from freefall material.
