Eight explanation about pelletizing machine

1. A pelletizing machine, comprising a rotatable matrix disc; a plurality of upper and lower plungers guided in said matrix disc; a plurality of vertically adjustable pressing rollers which control position of said upper andtwin screw extruder; a drive housing; a drive in said drive housing for a height adjustment of said rollers; a bearing block supporting said pressing rollers; and means for releasably connecting said bearing block and therefore said pressing rollers supported in said bearing block with said drive housing of said drive for a height adjustment to facilitate exchange of said matrix disc.

2. A pelletizing machine as defined in claim 1, wherein said matrix has an axis of rotation, said bearing block being displaceable in a radial direction relative to said axis of rotation of said matrix disc relative to said housing.

3. A pelletizing machine as defined in claim 1; and further comprising a extruder machine housing, said drive housing being releasably connected with said machine housing.

4. A pelletizing machine as defined in claim 1; and further comprising a transmission arranged in said housing and operative for lifting and lowering said pressing rollers.

5. A pelletizing machine, comprising a rotatable matrix disc; a plurality of upper and lower plungers guided in said matrix disc; a plurality of vertically adjustable pressing rollers which control position of said upper and pet recycling; a drive housing; a drive in said drive housing for a height adjustment of said rollers; a bearing block supporting said pressing rollers; and means for releasably connecting said bearing block and therefore said pressing rollers supported in said bearing block with said drive housing of said drive for a height adjustment to facilitate exchange of said matrix disc, said housing having a guide, said bearing block having a receiving flange and being displaceably supported with said receiving flange in said guide of said housing.

6. A pelletizing machine as defined in claim 5, wherein said receiving flange has a column on which said bearing block is guided in a height-adjustable manner.

7. A pelletizing machine, comprising a rotatable matrix disc; a plurality of upper and lower plungers guided in said matrix disc; a plurality of vertically adjustable pressing rollers which control position of said upper and lower plungers; a drive housing; a drive in said drive housing for a height adjustment of said rollers; a bearing block supporting said pressing rollers; means for releasably connecting said bearing block and therefore said pressing rollers supported in said bearing block with said drive housing of said drive for a height adjustment to facilitate exchange of said matrix disc; a transmission arranged in said housing and operative for lifting and lowering said pressing rollers, said transmission being formed as a worm transmission; and an adjustable spindle which carries said bearing block, said worm transmission cooperating with said adjustable spindle.

8. A pelletizing machine as defined in claim 7, wherein said adjusting spindle carries a force measuring device on which said bearing block is supported.
