摘要:
An induction heating roll device includes first and second resin processing bodies which roll or knead the resin material by interposing the resin material between the first and the second resin processing bodies. At least one of the first and the second resin processing bodies is a roll 5a. An induction heating coil 25 which is provided inside of the roll 5a and a cooling medium supply device 27 which supplies a cooling medium to a cooling medium flow channel 37 which is formed inside of the roll 5a are further provided. The induction heating coil 25 performs induction heating of the roll 5a, and the cooling medium supply device 27 cools the heated roll 5a by supplying a cooling medium to the cooling medium flow channel 37.
摘要:
A squeezing-roll granulator which has a squeezing roller pair (60) made of a toothed pressure roller (2) and a toothed squeezing roller (3), wherein the toothing (4) of the pressure roller and of the squeezing roller has tooth flanks (5, 6) which are arranged between a tooth base region (7) and a tooth crown region (8 8'), and wherein the tooth base region has an outer diameter (d) which is smaller than the outer diameter (D) of the tooth crown region, and wherein at least one of the two rollers of the squeezing roller pair has three squeezing zones (9, 10, 11) in the tooth crown region comprising a central squeezing zone (10), these zones define different spacings between the tooth crown regions with a minimum spacing (a) in the region of the central squeezing zone, and wherein the contour of the tooth flanks and of the tooth base region of the rollers of the squeezing roller pair defines a maximum cross section of the granulate cushions (12) to be formed.
