A belt-type automatic magnetic separator
was installed at the inlet of the primary cone crusher.
This device is essential to prevent metallic fragments—such as lost tools or
parts—from entering the crusher with the ore, which could cause severe abrasion
and shorten equipment lifespan.
In addition, the hydraulic pipelines
between the Cone Crusher and the Hydraulic Power Unit (HPU) were
connected, and the hydraulic pressure gauge panel was replaced.
The cone crusher operates via a hydraulic power system; oil circulation within
the crusher must be active before the power switch can be engaged.
The HPU functions as a safety control system, ensuring proper hydraulic
pressure and preventing overload during operation.
