Milltronics MMI belt scale 

USA - Milltronics MMI Belt Scale

Milltronics MMI is a heavy-duty, high accuracy multiple idler belt scale used for critical process and load-out control. The Milltronics MMI belt scale consists of two or more MSI single idler belt scales installed in series. It provides high-accuracy continuous in-line weighing of a variety of products in primary and secondary industries. 

The MMI belt scale system is proven in a wide range of tough applications from extraction 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 Milltronics BW500 or SIWAREX FTC integrator (for custody transfer applications), the MMI provides indication of flow rate, total weight, belt load and belt speed of bulk solids materials on a belt conveyor. A 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. Note: Idler not included with belt scale
