Improved Performance Without Sacrificing Safety

Siemens Solution at World's Largest Producer of Phosphate Ore

The Challenge

Apatit, part of the PhosAgro group, is the largest producer of high-grade phosphate ore and Russia's only producer of nepheline concentrate.

A recent challenge saw them start a search for a belt scale supplier. Given the nature of their mining, the company had high requirements in terms of reliability and accuracy for heavy duty applications. They also sought to reduce the maintenance time, requirements for spare parts, and wanted to modernise their production processes.

Conveyor belt scales are designed to continuously calculate bulk material flowrate by measuring belt load and speed. They can be installed in many locations throughout a mine or mineral processing operation for rate control, production, and inventory monitoring. Proper selection is important because with increased accuracy comes great cost.

The Siemens Solution

Belt scales work by responding to vertical forces. Many issues are a result of problems with the conveyor or improper commissioning. Careful evaluation of the application, proper installation, calibration and routine maintenace will yield many years of continuous, and reliable service. A typical belt scale system is made up of a weighbridge structure supported on load cells, electronic integrator, a nd a belt speed sensor.

Siemens were able to offer the Milltronics MSI belt scale and the Milltronics MMI belt scale. The compact design of the single idler model allowed for quick and easy installation, as well as reduced the amount of total weighing space required. This allowed for a more suitable area in the conveyor to be selected. A Sitrans WS300 speed sensor mounted on a self-cleaning bend pulley or a Milltronics RBSS return belt speed sensor, a calibration test chain, and a Milltronics BW500 integrator completed the belt scale soltion from Siemens.
