摘要： A pelletizing apparatus for the production of pellets from a melt flow comprising a pelletizer (12, 112), a cutting chamber (14, 114, 172), and a suspension structure (4, 104) for suspension of the pelletizer (12, 112) and/or the cutting chamber, wherein the suspension structure (4, 104) has a stationary portion (8, 108) and a portion (6, 106) connected rotatably about an axis of rotation (18, 118) to the stationary portion (8, 108) by means of a joint (16, 116).
According to the invention it is proposed that the pivotable portion (6, 106) has a substantially horizontal support arm (20, 120) which extends from the axis of rotation (18, 118) and has a distal end (22, 122), wherein in the region of the distal end (22, 122) the pivotable portion (6, 106) has a support (10, 110) adapted to support the pivotable portion (6, 106) in a vertical direction (24, 124).

摘要： The invention relates to a die assembly for a pelletizing apparatus, the die assembly having a pressure regulating device that has a base member, a flow channel, and an annular channel. The base member has a fluid inlet side and a fluid outlet side. The flow channel is formed in the base member to provide a fluid-conducting connection between the fluid inlet side and the fluid outlet side. The annular channel section is connected to the flow channel in a fluid-conducting manner and formed in the region of the fluid outlet side. The invention is characterized by a flow cross-section regulating element for influencing a flow cross-section of the annular channel section. The regulating element is movable relative to the annular channel section and/or the flow channel.

摘要： The invention concerns a quick-action clamping apparatus (8, 108), in particular a one-hand quick-action clamping apparatus (8, 108), for clamping a first assembly (36, 136) of a pelletizing apparatus (2, 102) to a second assembly (38, 138) of the pelletizing apparatus (2, 102), in particular a pelletizer (4, 104) to a cutting chamber (6, 106). According to the invention there is proposed a mounting element (44, 144) which is arranged at the first assembly (36, 136) or the second assembly (38, 138), a locking element (40, 140) which is arranged at the other of the first assembly (36, 136) or the second assembly (38, 138), and a clamping means (10, 110) having a clamping element (32, 132), wherein the clamping element (32, 132) is mounted rotatably about an axis of rotation (D) to the mounting element (44, 144) and the clamping element (32, 132) is adapted to be pivoted into a clamping position (S) in which the clamping element (32, 132) is in engagement with the locking element (40, 140) and braces the first assembly (36, 136) against the second assembly (38, 138). The invention further concerns a pelletizing apparatus (8, 108) and a method of bracing a pelletizer (4, 104) to a cutting chamber (6, 106).

摘要： A die plate changing system holds first and second die plates and selectively transitions the first and second die plates into and out of communication with a material source. The die plate changing system has a frame having a body defining a first recess that receives the first die plate and a second recess that receives the second die plate, where the frame is heats the first and second die plates when the first and second die plates are disposed in the first and second recesses, respectively. The die plate changing system also includes a movement assembly operably coupled to the frame and that selectively moves the frame between a first position, where the first die plate receives material from the material source, and a second position, where the second die plate receives the material from the material source.
