Continuous crusher operation with better level measurement

Oct 01, 2019 A large mining operation in Peru runs three crushers and three secondary crushers to process 18,000 tons of material every day. Operators never knew the level in their secondary crusher because dust interfered with non-contact measurement instrumentation, and there was a limited amount of space to mount a sensor.

Crusher level measurement and feed control VEGA

To achieve this, the ore is crushed to the correct size in two stages, in a primary and then a secondary crusher. In order to enable an optimum throughput, and avoid choking or damaging the crusher, a reliable level measurement is required.

Secondary Crusher /Tertiary Crusher Hawk Measurement

Tilt switch will work as a high-level switch only but not fail safe. A non-contact technology, like a 20 kHz acoustic transmitter, is the best choice because of its narrow beam, self-cleaning capability, not affected by background noise in the crusher and will see through dust. Acoustic transducers have the ability to see through dust.
