This automated ‘TMT Tornado’ system is used to produce cementitious slurry for a continuous paste fill plant for ground stabilization in the underground zinc mine.

This plant features an SD1000 automated colloidal mixer, agitator tank, progressive cavity pump, mag-flow meter, PLC control system and MCC for continuous slurry output to the larger paste fill system.

Slurry is produced automatically on demand. As the agitation tank drops to a pre-determined setpoint, additional batches are initiated as required. Progressive cavity pump control and slurry flow readings are assigned to the main paste fill system where the slurry is introduced into a twin-shaft pugmill along with other components.

Typical of all ‘TMT Tornado’ plants, this system is self-cleaning, after every batch. The plant features the newly designed mark III colloidal mills with an improved sealing system and automatic grease purging.

This site is located at approximately 16,000 feet in the Andes and offers spectacular views in all directions along with the interesting culture of the people of the Peruvian Andes.
