Abstract

An apparatus and method for sensor and control system, which automatically adjusts a product splitter position of a full-scale spiral. An electrical conductivity-based automation system is described and claimed herein and has been successfully developed and demonstrated as illustrated herein. The system includes a sensor and a microprocessor based and controlled servo or gear motor that is utilized to adjust the splitter of an operating coal/mineral spiral based on the readings of the sensor. The device as described and claimed herein converts a traditional coal spiral to an automated system for controlling the splitter thereby giving the spiral unit the ability to automatically adjust a key process variable, i.e., its splitter position, in real time as and when the feed coal or other mineral property changes to maintain the performance of the spiral at the optimum level.
