Shredding plastic film or paper: Select the reference blade diameter (200-300mm), thickness (20-25mm), and tooth pitch (30-40mm).

Wood or plastic drums: Select the reference blade diameter (300-400mm), thickness (25-35mm), and tooth spacing (40-50mm) 

Scrap tyres or cables: Select reference blade diameter (400-500m,m), thickness (35-45mm), pitch (50-60mm)

2. Thickness Reference For Each Type of Blade

Small blade (200-300 type): 20-30mm, suitable for low-strength materials. 

Medium blade (400-500 type): 30-45mm, suitable for medium hardness materials (such as wood, plastic). 

Large blade (600 type and above): 45-55mm, for high wear-resistant materials (like tyres, metals).

Shaft sizes

The total width of a single set of blades (multiple stacked) is usually 300-1200mm. 

Small machines: 300-500mm total width, suitable for 1-5 tonnes per hour. 

Large machines: 800-1200mm total width, suitable for over 10 tonnes per hour. 

Pitch and number of teeth

Pitch: Usually 30-80mm, and the harder the material, the bigger the pitch. When dealing with metal, the pitch is 50-80mm to prevent jamming. 

Number of teeth: 200mm diameter blade about 8-12 teeth, 600mm diameter blade about 16-24 teeth, the more teeth, the higher shear precision.
