For internal quality control purposes, an old belt scale that was installed but not used any longer was to be put into operation once again in the BMK plant in Ilsfeld. The technical specifications of the weighing cells were unknown, as were the data of the installed speed sensor.

The new Siemens weighing module for belt scales, SIWAREX WP241, was selected for this task. By using this transmitter, all customer requirements could be implemented without any problems. Due to the open concept of the SIWAREX weighing electronics, the customer was able to perform the renovation as well as commissioning himself.

The BMK Steinbruchbetriebe Company operates quarries at four different locations near Heilbronn, Germany in which it mainly mines limestone. An old belt scale was brought back to life at the BMK plant in Ilsfeld. The transmitter utilized with the belt scale there ensures open and flexible weighing processes. Its main area of activity is the mining of limestone, which is mainly processed into rock powder, sand, crushed rock and gravel. The various granulations and mixtures are used in civil engineering and roadway construction as well as in the production of concrete and asphalt. The conveyor output of belt scales range from 1t/h to 12,000t/h. Belt scales can be used in many areas. In addition to rock and coal mining, conveyor belt scales are used for weighing processes in many other industries, such as the cement industry, food and beverage industry or in the chemical industry.
