Method and device for encasing solids

摘要

The method involves moisturizing and coating a solid (4) e.g. expanded clay, in respective rotation states (2, 3). The solid is sieved before coating and before and/or during moisturizing the solid. The sieving of the solid takes place for removing fine parts such that formation of secondary granulates and cement parts is reduced. A large amount of water is sprayed on the solid for moisturizing the solid. The moisturizing of the solid takes place on a rotary inclined plate i.e. granulate plate. An additive e.g. calcium hydroxide rich material, is added during coating of the solid. An independent claim is also included for a device for coating a solid.
