Abstract

PURPOSE: To obtain granules of good hardness by detecting pressurizing force between granulating rollers with load cells provided at sides of one of the rollers and regulating the number of rotations of a raw material supply part in accordance with deviation between the force and a preset standard press. value to control the force.
CONSTITUTION: By rotation of screw shaft 7 in raw material supply part 6, raw material is filled between granulating rollers 2a, 2b. Sides of roller support parts 9b, 9b' of roller 2b are in contact with load cells 15, 15' connecting to load cell fittings 16, 16' fixed to granulator body 1. The raw material between rollers 2a, 2b is press. granulated with oil press. applied to pistons 11, 11' of hydraulic damepers contacting to sides of rollers support parts 9a, 9b of roller 2a. The pressurizing force between the rollers is detected with cells 15, 15' and compared to a preset press. value. In accordance with the deviation, the number of rotations of the raw mateiral supply part is regulated to control the force so that it is always within a control limit.
