The primary Cone Crusher (150HP) can crush
the ore processed from the main Jaw Crusher at a rate ranging from 100 tons up
to 150 tons per hour.
Given the high power requirement of this primary Cone Crusher, its motor was
sent to a specialized service provider for inspection and maintenance to ensure
operational stability.
Finishing work was carried out on the raw ore inlet at the main Jaw Crusher. To prevent ore from scattering outside the hopper during feeding, the gap between the hopper and the exterior wall of the processing plant was sealed using surplus rubber belts.
Additionally, the inner wall side and the inside of the hopper were finished by
cutting and welding flat steel plates for secure attachment.
