Grain cleaner ALS-20 (20 – 40 t/h)

The most important parameter that ensures productivity is the width of the separation chamber. The wider the separation chamber – the wider the separator’s hopper is, and the wider the hopper – the wider the grain layer is. A wider layer of grain provides a bigger grain pouring to the separation chamber and, accordingly, productivity. Sure, you can increase the pouring by increasing the thickness of the grain layer from the hopper, but in this case you can forget about the quality of separation. A more powerful fan will also not save you, because the collision of seeds in a thick layer happens too often, and the separation becomes a chaotic process.

The wing impeller alone is not suitable for use in cleaning devices. It produces a stream that is heterogeneous in cross-section and very turbulent, the air moves progressively, rotatingly and swirls – turbulence appears. Whereas, our ALS separators have a very effective aerodynamic system thanks to a special straightening device (straightener) developed by our engineers. It is installed directly after the impeller and eliminates all the above-mentioned drawbacks of the wing impeller itself. The presence of a straightener in our separators increases the precision of grain separation by 20-30% compared to separators with only the rotor and fan.

ALS separators can be equipped with additional options to increase productivity and improve grain processing. We have developed VOK cyclones (dust collectors) – technologically advanced systems of suction and deposition in a special chamber of all the lightest impurities (dust, chaff) flowing out of the ALS through the light fraction discharge channel.

New device! We have developed and produced additional equipment for the ALS aerodynamic separators – light fraction catcher (ULF). The main function of the new device is to catch and hold light impurities from the air stream coming out of the separator.

When the extent of impurity of the starting material exceeds 5% or you have a grain mixture to clean or herbs seeds, we highly recommend using additional cleaning equipment – OSC scalper. It separates any coarse fractions from the starting material such as stones, pieces of ground, straw, spikelets, sticks etc. OSC is designed to work together with the ALS grain cleaner, but can also be used separately as a pre-cleaner.
