Tumbler screener for multi-deck screening in powders and granules
Achieve precise separation and de-dusting of powders and granules with up to seven fraction outputs, ensuring consistent product quality even with challenging fine or delicate materials.

Separates and Screens Multi-sized Particulate Materials
The GKM Ultimate Tumbler Screener, distributed by Kemutec, is a versatile flat deck screener designed for efficient separation and de-dusting of powders and granules. Its multi-deck construction allows up to seven particle size fractions to be seamlessly sorted, accommodating feed sizes from 1 micron to 20 mm. This solution excels in industries ranging from food processing and pharmaceuticals to chemicals and minerals, producing end products such as whey protein isolate and chewable pet tablets. With the capability to process up to 50 tons per hour, the screener supports high-speed, continuous operations.
Incorporating advanced 3D motion technology, it delivers gentle handling to avoid material degradation while ensuring high separation efficiency, achieving up to 99% accuracy. The tumbler’s modular design facilitates easy adaptation to specific materials and offers a variety of screen types, including stainless steel, to handle different applications. It is compliant with FDA, GMP, and ATEX standards, supporting clean and controlled processing environments, and equipped with ultrasonic cleaning for maintenance-free operations. Additionally, this equipment provides options for enhanced efficiency with reduced power consumption and noise levels below 75 db(A). Custom engineering support is available, allowing tailored configurations to meet specific processing needs.
