| 摘要 |
The present invention relates to a process for the production of granules from a liquid composition with a decreased dust production, said process comprising the steps of; applying the liquid composition onto solid particles that are kepi in a continuous movement by a gas stream in a granulation zone of an oblong granulator, thereby depositing and solidifying said liquid composition around said solid particles to increase the size of the particles and thereby form grown solid particles; discharging a stream υsaid grown solid particles from the granulation zone, dividing, in a size-sorting apparatus, said stream of said grown solid particles into individual streams based on the size of said grown solid particles to thereby produce streams of undersized, oversized, and desired-sized grown solid particles; transferring said stream of said oversized grown solid particles to a size-reducing apparatus; crushing said stream of said oversized grown solid particles in said size-reducing apparatus, thereby reducing the particle size of said oversized grown solid panicles and thereby producing a stream of crushed solid particles wherein that said stream of crushed solid particles is introduced in the granulator at a place below the place where the gas stream leaves the granulator. |
