Indonesia is the world’s largest palm oil producer, and its processing operations generate substantial volumes of palm kernel shells, palm meal, and fiber as by-products. After proper screening, these materials can be used as biomass fuel, animal feed, or organic fertilizer, creating significant economic value. Meanwhile, Kazakhstan, a major grain producer and exporter in Central Asia, requires cleaning, impurity removal, and grading of wheat and barley before storage and processing. Screening accuracy directly affects grain grade and export pricing. The FY series square gyratory sifter, with its high capacity, gentle screening action, and fully enclosed structure, proves highly adaptable in these two very different agricultural processing scenarios.
The FY sifter’s screen box performs a near-circular planar rotation, with material entering at the center and spreading slowly outward in a spiral path. This imitated hand-sifting motion gives material longer residence time and fuller contact with the mesh, ensuring efficient fines penetration without violent impact. For fibrous, light, and easily tangled materials such as palm kernel shells and palm meal, the FY sifter effectively separates shells from kernels and removes impurities. The mesh resists clogging, and the bouncing ball cleaning system supports long continuous runs. Multiple decks allow different by-product fractions to be produced in one pass, meeting specifications for biomass fuel or feed.
In Kazakhstan’s grain cleaning operations, the FY sifter handles primary cleaning and grading of wheat, barley, and corn. Its gentle planar rotary motion does not damage grain hulls or embryos, resulting in a breakage rate far lower than that of high-frequency vibrating screens — helping preserve germination rate and processing quality. The fully enclosed structure with dust extraction ports controls dust during grain cleaning, improving the workshop environment and meeting environmental requirements. The high-capacity design allows a single machine to process tens of tons of grain per hour, making it suitable for continuous operation at grain collection centers and flour mills.
The FY square gyratory sifter features low drive power, low noise, and low dynamic load. It can be installed in existing plants or on steel platforms without heavy foundations, facilitating retrofits and capacity expansion. THZD can customize screen material, aperture, and deck number according to material characteristics, and offers sanitary configurations for grain and agricultural processing. For Indonesian palm oil by-product processors and Kazakhstani grain processors, the FY square gyratory sifter is a practical choice for improving screening efficiency, reducing breakage, and lowering operating costs.
