The metal to be detected varies widely based on the specifics of the equipment being protected. For example, a cone crusher with a 1” gap can pass ½” metal without causing a problem, but a 1.25” piece of metal will likely cause some damage. In underground mining, roof bolts can become mixed in with the product and spear and tear belts at
