The high concentration of dust in the grain handling environment holds serious health risks for employees, while at the same time increasing the risk of dust explosions. Senwes’ goal was to reduce these risks by installing an ecient and cost eective dust extraction system were the liability was tested to be the highest. Roff Industries was appointed to design, supply and install the system making use of the Jacob Pipework System.
After completion, the dust in the environment was reduced to safe working levels and employees no longer needed the use of dust masks. The risk of explosion was also drastically reduced, as all the parts in the Jacob range were conductive without the need for further grounding.
Senwes’ Grainlink silo infrastructure is strategically placed in all the major grain cultivation areas of South Africa. With a capacity of no less than 4,6 million tonnes, the infrastructure constitutes more than 25% of the total South African commercial storage capacity. Grainlink has 65 silo sites in the North West and Free State province, making them one of the biggest suppliers in the industry. Directly after the grain is received from the surrounding farms and sea ports, it is distributed by means of road-freight to millers, feed producers and other sectors throughout South Africa.
The Jacob modular pipework system is between 100 and 200 diameters and was selected along with the Quick Connect clamps and U-Shaped seals. As a result of the quick installation utilising the Jacob system, downtime was significantly minimized. The seals drastically reduced leakages and made the system more power efficient by reducing the motor size on the fan. Roff produced the custom built high efficiency cyclone and frame, as well as supporting brackets.
