The Kaltech Sentinel System

The Kaltech Sentinel is the safest and most efficient tool for capturing internal mill conditions through the use of empirical data and live observation. As a custom designed and engineered mill monitoring system, the Kaltech Sentinel is permanently installed to enable remote viewing and monitoring of the condition and wear of mill liners. It consists of two main components: the Sentinel Camera Unit (SCU) and the Electronic Bolts (eBolts).

By combining imaging technology with liner wear-monitoring hardware, the Sentinel system reveals live information from within a mill without the need to pull the feed chute or have personnel enter inside.

Viewing and recording live imagery of a running mill, measuring the wear of a liner, assessing the internal conditions, and checking or setting the charge level, are all now possible in real time without the need to isolate any plant or equipment.  Access to this information presents new opportunities for improving operational metrics, reducing running costs, and provides a detailed empirical basis for liner-life prediction and maintenance planning.
