YARA Thailand
Yara, Thailand In September 2015, Yara Thailand signed a contract with EMT for the supply of machines for 25–50kg filling bags, fertiliser coating and a transport system of portable conveyors to fill the bagging line directly out of river barges.
The project was designed and developed to meet technology, health and safety regulations.
Before EMT installed the machines, the bagging process was conducted manually, which required a large workforce. Additionally, the accuracy of the weighing process needed to improve in order to reach Yara’s required standards and quality.

Custom designed
EMT constructed, delivered and installed the machine line in 2016. Indeed, 16 x 40ft high cube containers were shipped from the EMT factory in the Netherlands to Thailand.
EMT has its own designing engineers so the machines were modularly built and bolted together in the existing warehouse of the customer.
This meant no civil works to the building or concrete floor structure was required.
Eight fully closed stainless steel conveyors were supplied. These conveyors were mounted on wheels and are used to transport the fertiliser over the quay from the barge to the bagging lines. Two stainless steel harbour intake hoppers were also supplied.
Factory setup
When the fertiliser enters the warehouse, three screens with lump breakers are used to eliminate lumpy material. Then three stainless steel elevators, each with a capacity of 120 tonnes, transport the product to quarto bagging lines where a duplex weighing system was installed.
Stainless steel air exhausting filters are located on top of these bagging lines and a unique air dryer system is used. The bags are then closed with a four needle sewing system.
The third line is a truck/container offloading conveyor system. This line has a weighing belt conveyor to check the product flow and a unique blending scroll auger to coat the fertiliser before bagging. The factory is operated from a central control room, where complete factory visualisation is possible on two 20 inch flatscreen computers.
The line is fully controlled by a PLC and PC. All bagging lines are connected to this central control system so that the operator can control the factory from this room.
All generated data is stored in the computer system. In this machine set up, six lines are placed next to each other, with a total capacity of 300tph.
Robots
Two robots are installed in two lines, with the possibility of adding another four robots in a later stage, meaning a total of six robots can be installed.
Using robot arms for the heavy work creates a safe working environment for Yara’s employees.
As a supplier of blending, bagging and transport equipment for the fertiliser industry, EMT is constantly improving its machines and plans to work as efficiently as possible when developing new technologies.
