SMS series metal detecting separators are highly sensitive and accurate in detecting and separating metal grains, such as steel, iron, copper, aluminium, lead, tin, and so on. Its principle is when metal impurities pass through it, electrical detector can send a signal to control board to start valve to discharge the impurity materials. Pneumatic discharging system takes little space and ensures good performance. It can be installed directly on injection moulding machine or (extruders) hoppers to protect the screw of machine from the damage caused by hard metals. There are three models of the series: SMS-35~70, processing capacity can reach up to 400L/hr~5,000L/hr to meet any specific requirement.
