Page 5: Milltronics Mmi Belt Scale
Milltronics MMI Belt Scale Milltronics MMI belt scale is a heavy-duty, high-accuracy multiple idler scale for critical process and load-out control. The MMI uses two Milltronics MSI belt scales in succession. The scales are designed to be inserted into belt conveyors for continuous weighing of dry bulk solids. -

Page 9: Installation
Each MSI weighbridge must be removed from its shipping frame and inspected for physical damage. Be sure the conveyor design meets the installation requirements for the Milltronics MMI belt scale. The conveyor stringers must be rigid, straight, parallel to and square with the belt line in the area of the scale installation. -
Page 10: Installation Procedure
Remove the conveyor idler currently at the desired point of installation. Remove the idler foot plate and modify the idler frame at both ends of the idler as shown below. customer’s idler 12.7 mm (0.5”) 100 mm (4”) before after Page 6 Milltronics MMI Belt Scale – INSTRUCTION MANUAL 7ML19985DR02... - Page 11 Position the scale so that the large arrow on the scale mounting brackets is pointing in the direction of material flow. idler clips conveyor stringer (typical) 7ML19985DR02 Milltronics MMI Belt Scale – INSTRUCTION MANUAL Page 7...

Idlers must be flat, 20 or 35 degree trough angle. All idlers on the conveyor must have the same trough angle. g. Training idlers must not be located within 60 ft of any scale weigh idler. Page 10 Milltronics MMI Belt Scale – INSTRUCTION MANUAL 7ML19985DR02... -
Page 15: Calibration
Perform the span calibration as described in the Calibration section of the integrator instruction manual. After the span calibration has been completed, remove the test load and store it. test weight(s) 7ML19985DR02 Milltronics MMI Belt Scale – INSTRUCTION MANUAL Page 11... -

Re-Rating To be sure that proper design parameters are maintained, consult your Siemens Milltronics representative for any significant change in rate, speed and /or idler spacing from original design specifications. -
Page 17: Maintenance
When welding near the scale, do not allow current to pass through the belt scale. • Reset the shipping stops to reduce physical shock to the load cells during maintenance. • Recalibrate the scale after maintenance and prior to use. 7ML19985DR02 Milltronics MMI Belt Scale – INSTRUCTION MANUAL Page 13... -
