The Eriez® Model 1200 Series Metal Detectors detect both ferrous and nonferrous tramp metal in magnetic ores, highly mineralized products and food products… even when conveyed on steel-corded belts. From detecting medium and larger ferrous and nonferrous particles traveling at speeds up to 1200fpm (363mpm), to detecting small pieces of metal in wet conductive products, Model 1200 Series Metal Detectors provide a solution.
The 1200 Series detection system operates by measuring the change in received electromagnetic signal of material being conveyed through the sensor area. Since the magnetic properties of a material are completely independent of conductivity, both magnetic and nonmagnetic tramp metals are consistently detected.
The Model 1230 Metal detector is engineered for installation on conveyor belts carrying coal, minerals, aggregates and other bulk materials. it can be tuned to ignore conductive or magnetic ores such as magnetite and pyrite, even if they are carried by high tension, steel corded belts with rip detection loops, while still detecting small pieces of tramp metal.
