Yara, the UK market leader in the supply of plant nutrient products to farmers and growers, have recently installed a new blending and delivery system in Dagenham where they have storage and despatch facilities for their range of liquid fertilisers that serves the South West of England.
In an alliance with TDG, the chemical logistics specialists, Yara blend and supply liquid fertilisers which are then transported to their customers in the South West. The new dedicated system was designed by Practicon, a Stoke-based company specialising in weighing systems and batch process control. The Practicon control system allows inline blending through a flow mixer of urea and ammonium sulphate into blending holding tanks. These tanks are then electronically made available to loading lines for a road tanker driver to draw off the grade and volume of liquid fertiliser required. Where a different grade is required to that of the pre-blended tank, then the system will draw the liquid fertiliser from both the urea and ammonium sulphate loading lines. Full traceability is recorded.
The Practicon system provides a number of benefits to our operation. Automation eliminates human error and maximises efficiency. The pre-loaded recipe system for the mix process ensures that the correct grade of fertiliser is achieved. What is an added bonus is that the Practicon system integrates with an industry standard Siemens PLC solution with utilising Profibus PA fieldbus technology, said Alan Capindale Production & Engineering Manager at Yara.
TDGs Les French said, Our operators like the Practicon system because of its efficiency and user-friendliness, and the control and accuracy of the transfer of the product.
Martin Jones, System Designer at Practicon, said, We worked very closely with Albright Engineering who designed the Dagenham plant to ensure that our system met Yaras and TDGs requirements for full automation.
