Product Overview
Polyurethane finger star wheel is cast from wear-resistant PU material with square center bore. It gently conveys and separates stones from root crops during rotation, absorbing impact to protect products. It is the key spare part for potato destoners, harvesters and screening machines.
Key Features
Excellent Wear Resistance
Made of high-grade polyurethane, abrasion and tear resistant for long service life under continuous material impact.
Gentle Material Handling
Curved finger design conveys materials softly, reducing bruising and damage of potatoes and root crops.
Stable Square Drive Bore
Central square hole fits drive shaft tightly for stable power transmission without slipping.
Impact & Aging Resistance
Tough PU material withstands heavy impact and wet muddy conditions, resisting crack and deformation.
Self-cleaning Surface
Smooth curved fingers prevent material sticking, maintaining stable sorting performance.
Easy Replacement
Modular design for quick assembly and disassembly, minimizing machine downtime.
