Milltronics MMI - Multiple Idler Belt Scales
NTEP and Industry Canada approved for certified weighing applications

Click here to download catalog sheet for the Milltronics MMI Belt Scale

MMI - Multiple-Idler Belt ScaleThe MMI belt scale system is the only scale possessing an NTEP Certificate of Compliance with only two scale idlers.

Because of this, Milltronics offers (by far) the least expensive system for certifiable belt scale applications in coal, aggregates, and other industries that we serve.

Milltronics MMI belt scale is a heavy-duty, high-accuracy multiple idler scale for critical process and load-out control. The MMI consists of two or more MSI single idler belt scales installed in series. It provides high accuracy continuous in-line weighing on a variety of products in primary and secondary industries. The MMI system is proven in a wide range of tough applications from extraction - in mines, quarries and pits - to power generation, iron and steel, food processing and chemicals. The MMI is suitable for monitoring such diverse products as fertilizer, sand, grain, flour, coal or sugar.

The MMI's patented use of parallelogram style load cells results in fast reaction to vertical forces, ensuring instant response to product loading. This enables it to provide outstanding accuracy and repeatability even with uneven or light loading, short idler spacing and fast belt speeds.

Operating with one of Milltronics' microprocessor-based integrators, the MMI provides indication of flow rate, total weight, belt load and belt speed of bulk solids materials on a belt conveyor. A Milltronics speed sensor monitors conveyor belt speed for input to the integrator.

The MMI is installed in a simple drop-in operation and may be secured with just eight bolts and existing idler sets, secured to the dynamic beam. With no moving parts, maintenance is kept to a minimum, with just periodic calibration checks required.

  • Exceptional accuracy and repeatability
  • Unique parallelogram style load cell design
  • Immediate reaction to product loading
  • Suitable for uneven or light product loading
  • Capable of monitoring fast moving belts
  • Low cost of ownership
  • NTEP and Measurement Canada approved
  • National Type Evaluation Program (NTEP) and Industry Canada approved for certified weighing applications when used with the Siemens Accumass BW 500 Integrator and the Milltronics MD-36A speed sensor.  An NTEP certificate has been recently processed to approve the use of the Milltronics Accumass BW500 Integrator for certifiable systems.
