Belt Conveyor Weightometer – Electromagnet and Metal Detector

Belt Conveyor weightometers are required to accurately weight and chart the tonnage throughput. An operator is able to catch many problems that are developing simply by watching the tonnage. A drop or increase in tonnage can indicate something going wrong .within the system. MAGNETS, These capture what is known as "TRAMP METAL". This is metal that has gotten into the ore flow and could ...

Belt weigher - Glossary - Schenck Process

Belt weigher. A belt weigher is used to determine the mass of the material transported on a conveyor belt. The weight of the material transported is determined by weighing the belt load and measuring the belt speed. The belt speed remains constant while the feed rate is regulated by varying the belt …
