On the drawings below you can see the working process of a bucket when it screens material. The procedure depends on the motion of rotor spinning.
Our blade designs can be divided in two groups:
Screening blades genuinely separates the materials without breaking sharp particles into screened material
Aggressive blades are designed to mince and brake the material like class, roof tiles, root lumps
Comb counter blades designed for purely screening and separating the material while aggressive counter blade is more for rough material and mincing the particles.
Blade screen technology is the best choice with moist materials. Rotating blades makes material to move up and down while cleaning scrapers, constantly empties rotators from sticky materials.
