摘要：The present invention relates to a process for the production of granules froma liquid composition with a decreased dust production, said process comprising the stepsof: applying the liquid composition onto solid particles that are kept in a continuous
movement by a gas stream in a granulation zone of an oblong granulator, therebydepositing and solidifying said liquid composition around said solid particles to increasethe size of the particles and thereby form grown solid particles; discharging a stream ofsaid 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 saidgrown solid particles to thereby produce streams of undersized, oversized, and desired-sized grown solid particles; transferring said stream of said oversized grown solidparticles to a size-reducing apparatus; crushing said stream of said oversized grown solidparticles in said size-reducing apparatus, thereby reducing the particle size of saidoversized grown solid particles and thereby producing a stream of crushed solidparticles wherein that said stream of crushed solid particles is introduced in thegranulator at a place below the place where the gas stream leaves the granulator.
