Description:
The Union Process Szegvari 1-S Series Laboratory Attritor is a high-efficiency lab-scale milling system, designed for fine grinding, particle size reduction, and dispersion applications.
With a 1.5-gallon tank capacity and 0.8-gallon working capacity, this attritor provides precision grinding in small batches, making it ideal for R&D, pilot-scale production, and laboratory testing.
The 7.5” diameter x 9” deep bowl ensures efficient material circulation, while the 1” diameter shaft provides consistent agitation for uniform particle breakdown.
Powered by a 1/2 HP, 3/60/208-220/440V motor, this attritor operates at 1800 RPM and features a Varidrive variable speed gearbox (14:1 ratio), allowing for precise control over milling speeds.
Mounted on a sturdy frame, this compact and efficient attritor is a cost-effective solution for laboratory milling needs.
