Pharmaceutical Gravity Feed Metal Detector

Pharmaceutical Gravity Feed Metal Detectors are designed to inspect any free flowing bulk powder or granular materials such as pharmaceuticals, plastic pellets, cereals, flour and chemicals. Any free flowing materials may be passed through the vertical drop system. The unit fits into an existing pipeline or beneath a feed hopper and the product fall by gravity. The metal free product passed straight through the mechanism and diverts the ferrous, non-ferrous and stainless steel contamination from the main flow. A frame with levelling pads or locking castors at the base make the system possible to move around the plant with the greatest convenience. Stainless steel metal detector, construction can be supplied with throughout systems are also available, suitable for floor or suspended mounting.
Target metal detectors incorporates a simplified and refined design of automatic balance coil principle which eliminates all setting up controls and permits long consistent performance. A frequency of about 100-200 khz is used to generate a electromagnetic field in the aperture area. The system automatically maintains a high degree of balance which is disturbed by the metal passing through the aperture resulting in a signal. This signals amplified and is used to actuate the relay which is again used to divert the contaminated products.
