Fertiliser dosing system with associated acid tank farm and milling plant
The plant consisted of an acid tank storage farm, milling plant with conveyor and piping systems to handle and condition the material.
The control panel was designed and manufactured by Axon and consists of control and power distribution for 20 motor starters (approx. 300A in total) which are switched using DOL and VSD starter assemblies.
The control system was mounted on an Allen Bradley PLC with associated HMI that can be used to control the plant in various sequence modes, as per the customer process requirements and to appropriately control the chemicals added to the material.
The control system also consisted of multiple remote IO stations to more effectively marshal the field instrumentation and reduce the cabling burden.
The panel and associated cabling were installed and commissioned on site by our projects team. This required extensive tuning of the plant control loops to ensure the correct chemical dosing was achieved for all customer scenario requirements. The electrical plant commissioning was completed by our site team including interface with auxiliary system e.g. milling plant, to ensure complete plant operation is as per customer specification.
