When should I use a fine shredder like HFZ V instead of a standard shredder in Australia?

The HFZ V is used after primary shredding when you need very fine output (around 5–10 mm), especially for biomass, pelletizing, or briquetting.
Unlike standard shredders, it uses a high-speed rotor with hammer technology to produce uniform, high-quality material. This makes it ideal for Australian recycling plants and energy recovery facilities.
