In under 4 years, Farallon Mining Ltd. successfully built a blind, greenfield discovery into the G-9 Mine at the Campo Morado project in Guerrero State, Mexico.

Team Mixing was selected as the supplier to provide a cemented rockfill (CRF) plant for backfilling the mined out primary stopes in the polymetallic orebody.

This continuous type CRF plant uses twin conveyor scales to monitor fine and coarse aggregate feed rates and make corresponding adjustments to cement and water flow rates via the PLC. The totalized quantity of aggregate, cement and water determines the final batch size, discharged directly into an awaiting haul truck.

Cement is pneumatically delivered to the cement silo and fed to the weigh hopper after each batch. Subtractive weighing is then used during the batch process. During a batch, a variable-frequency drive (VFD) is used to control the cement feed screw, discharging the cement weigh hopper. Similarly, a VFD controls the water rotary lobe pump with flow rate monitored by a mag-flow meter.

The PLC control system & touchscreen features multiple recipe selection, alarming and data logging for each batch.
