DEVICE FOR PRODUCING A GRANULAR MATERIAL

摘要

Prior art belt-type droplet-forming equipment uses an outlet slit which is disposed at right angles to the direction of motion of the perforated belt (1) and through which the material can pass into perforations in the belt. The invention proposes that the slit is replaced by several rows of apertures, the rows being disposed next to each other in the direction of motion of the belt and the apertures in adjacent rows being staggered with respect to each other such that the total aperture area over which the perforations pass is constant, irrespective of the path of the perforations. This design makes it possible to reduce the force exerted on the perforated belt by the compound pressed out on to the belt. The device is suitable for use in belt-type droplet-forming equipment.
