Page 9: Operation
Operation Weighfeeders Weighfeeders weigh bulk material while it is conveyed. An accurate rate of flow and totalized weight measurement is received without interrupting the flow of material in process. A weighfeeder can also control the rate of flow of the conveyed product. In-motion weighing requires accurate transmission of the product load to a strain gauge load cell(s). -
Page 10: Mechanical Installation
Mechanical Installation Perform a thorough and systematic inspection of containers immediately upon receipt of your weighfeeder. The containers are packed to separate each item and provide protection during shipping. Do not remove equipment from shipping crates or boxes until you check for Note: possible shipping damage. -
Page 11: Installation
Installation Only qualified personnel are authorized to install and operate this equipment. Note: Installation shall be in accordance with local regulations, standards and established safety practices. Read and understand the instructions before installing, operating or maintaining the equipment. Align the in-feed section of the weighfeeder with the discharge of the feed device. Prevent twisting or misalignment that could induce stress on the weighing section. -
Page 12: Calibration
Calibration After Milltronics Weighfeeder 1200 has been properly installed, calibration of the weighing system must be done in conjunction with the integrator. Refer to the integrator instruction manual for programming and calibration. The calibration is initially done using the supplied test load. Material tests are recommended to achieve maximum accuracy. Test Load The test load value for your Milltronics Weighfeeder 1200 is given on the accompanying test sheet. -

11. Shear Gate The shear gate on the inlet of the weighfeeder needs to be set to allow the maximum feedrate capacity requested by the customer. Consult your Siemens representative if feed rate changes are required. Skirtboards The skirtboards have also been factory set to proper specifications. Note that near the inlet, the skirtboards are very close to the belt. -
Page 15: Belt Tension
At the discharge end of the conveyor, find the belt scraper spring tensioner. Unhook the spring on both sides of the belt scraper arm and let the belt scraper swing down away from the belt. Skirtboard removal or adjustment is not normally necessary to perform belt Note: removal or installation, nor is it recommended. -
Page 16: Telescoper Adjustment
Re-tighten the jam nut located on the telescoper to maintain the new telescoper position after completing the tracking procedure. If you are having problems tracking the belt, consult your Siemens representative. Common causes of belt tracking problems are: uneven or improperly distributed product loading, twisted frame, or product build up on head or tail pulleys. -

• weigh idler alignment. Verify weigh idler alignment is as accurate as possible. Improper alignment is the most common mechanical problem affecting scale accuracy. Contact your Siemens representative if you find a problem here (should be 1/32” aligned with approach and retreat). -
Page 20: Maintenance
Maintenance WARNING: ALWAYS STOP the belt, lock-out, and/or place a "Do Not Ener- gize" tag on the main disconnect before working on or around the weigh- feeder. Preventative Maintenance The maintenance schedule below is recommended to maintain top performance and accuracy of the system. -
Page 21: General Maintenance
General Maintenance The equipment should be cleaned periodically and any excess accumulation of product should be removed to minimize potential damage to the mechanical components and scale accuracy. Abrasions, cuts, or ragged edges on the belt will create performance problems. Replace the belt if it becomes ragged or torn. - Page 22 Dimensions Open Unit 241 mm (9.5”) varies per drive belt width shown with optional sheargate and skirtboards belt scraper 1140 mm (45”) 2134 mm max. inlet (84”) discharge 1035 mm (40.75”) 123 mm (4.84”) 1524 mm (60”) Open Unit Belt Width 457 mm (18”) 1092 mm (43”) 838 mm (33”)
