Blades of the dual-shaft shredder

products Description

The design of the number of teeth, tooth shape, thickness and size of

the blade of the dual-shaft shredder is the core factor to achieve the

1.Shredding particle size of different materials

Number of teeth and tooth spacing：With a large number of teeth and a small distance between

teeth: The cutting points of the blades are dense, which is suitable for fine shredding (such as plastic

fragments and metal shavings). The finished product has a uniform and fine particle size (usually ≤ 50mm).

With a small number of teeth and a large distance between teeth: The blades form a

larger biting space, which is suitable for coarse shredding (such as large pieces of wood and tires). The

particle size of the finished product is relatively large (it can reach 100 - 300mm).

2.The Function of the Blade Thickness

Thick blades (≥20mm):Thick blades (≥20mm): They have high strength and strong impact resistance.

They are suitable for shredding hard materials (such as metals and glass), reducing the risk of deformation

or breakage.

Thin blades (≤15mm):The blade edge is sharp, with low cutting resistance. It is suitable for soft

materials(such as paper and cloth), which can improve the shredding efficiency.

Design logic: Match the thickness with the hardness of the material to balance wear resistance and

energy consumption.

3.The Influence of Blade Dimensions (Diameter/Width)

Large-sized blades: Increase the cutting area, and are suitable for handling large-volume materials

(such as used furniture and automobile casings), thus increasing the single processing capacity.

Small-sized blades: They can achieve higher rotational speeds and are suitable for scenarios that

require fine crushing or rapid cycling (such as electronic waste recycling).

Matching shaft spacing: The staggered design of the two-shaft blades (usually, the shaft spacing is

1.2 - 1.5 times the blade diameter) determines the volume of the shredding chamber and the material

passing rate.

4.Optimization of Tooth Shape and Surface Treatment

Sawtooth-shaped/Wolf tooth-shaped teeth: Enhance the material grasping ability and are

suitable for fibrous materials (such as rubber and plastics).

Smooth cutting edges: Reduce material entanglement and are suitable for sticky materials

(such as food waste).

Surface quenching/coating: Improve the hardness (HRC 55-62) and extend the wear-resistant

service life (especially for hard materials).
