Grinding Circuit Control Using Programmable Logic Controllers

This paper presents an application for cement milling system. In this application the process is controlled by software running on Programmable Logic Controllers. The appliance used to observe industrial process show the following mill parameters: feed rate, mill speed, transporters speeds, mill filling level, fan speed, circulating loads. The appliance monitors operations and process conditions and makes constant automatic adjustments necessary to stabilize the process flow, balance load between circuit equipment.
