Vibrating Screen for Cleaning the PKS for Export Oriented

One of the quality parameters for PKS or palm kernel shells for the export market is the cleanliness factor. This cleanliness factor is very much associated with a lot or  little impurities in it. PKS in palm oil mills are usually only piled in a back yard the palm oil mill. This is very possible to mix with a number of impurities that are in the vicinity of the location or because of a number of waste or garbage that might also be disposed of at the location of the PKS pile. PKS impurities commonly found are metal, plastic and stone. For export purposes, the amount of impurity allowed or tolerance level is very small, which is around 1%. Why does the PKS need to be cleaned in such a way? This is because the impurities will interfere with the combustion process or utilization of the PKS and the power plant is the largest user.

Manual Screener

Screener is the equipment used to clean the PKS from the impurities. The impurities or foreign materials will be separated from the PKS due to differences in size. And specifically for metal impurities, the separation is done by magnet (magnetic separator). The cleaning process with this sieve is basically very easy, even with a manual sieve it can be done. But for a large enough volume, for example up to thousands of tons, the manual sieve is inefficient and takes a long time, so it takes a sieve that works mechanically. There are two mechanical sieves that are commonly used, namely vibrating screen and rotary screen.

In practice the type of vibrating screen is more popular than the rotary screen. This is because the construction and operation of vibrating screens are easier, besides the price of vibrating screens is also cheaper than the rotary screen. Vibrating screen is a sieve that operates due to vibrations from eccentric movements. The higher the rpm the vibrating screen movement will be smoother. Both the vibrating screen can also be equipped with multiple sieves or multi-level sieves so that a number of product fractions can be obtained based on their size. It's just that it's also easier to do with a vibrating screen. In PKS sieving it is usually only one to three levels of sifting.

PKS needs for the Asian and European markets are predicted to continue to increase every year to reach millions of tons. This is because electricity production using PKS is increasing. PKS supply or supply mainly originates from Indonesia and Malaysia, as well as several countries in West Africa, the origin of palm oil trees. Indonesia and Malaysia mainly supply the needs of Japan and Korea in Asia while West Africa supplies countries in Europe. PKS as a biomass fuel also has competitors, especially wood pellets. PKS prices on the world market are much cheaper than wood pellets so that many biomass power plants prefer PKS. PKS production for export is also easier than pellet wood. Exports of PKS from Indonesia and Malaysia are quite large, because the number of PKS produced is also large, while the needs are also large. Besides that, the use of PKS in the country that is still small makes the PKS export more dominant
