The metal detector system in Pharmaceutical segment is widely used for detecting the external contamination in Tablets / Capsules.
The system for Tablet can be used in combination with vertical deduster system, which is specially designed high end equipment to remove the powder deposited / available on the tablet. The equipment is placed at the discharge of compression machine. Tablets are passed through the vertical deduster initially. The output of the deduster is feed to the metal detector unit, which checks for the external metal contamination in the Tablet.
The metal detector system can also be used for in capsule line. Normally, the system is placed after polishing of capsules, in the line. However, due to space constraint, sometimes, the units are placed after filling and before polishing.
