The reduction ratio is around 8:1 and as the product size is relatively small the feed size is limited to less than 50 mm with a nip angle between 25° and 30°. The Gyradisc crushers have head diameters from around 900 to 2100 mm. These crushers are always operated under choke feed conditions. The feed size is less than 50 mm and therefore the product size is usually less than 6–9 mm. View
