Description

Technical Field

[0001] The utility model relates to the technical field of granulators, in particular to a petroleum resin granulator. Background Art

[0002] A pelletizer is a molding machine that shapes materials into specific shapes. It is widely used in the chemical, petrochemical, pharmaceutical, food, building materials, mining, environmental protection, printing and dyeing, ceramics, rubber, and plastics industries. Energy conservation in a pelletizer can be divided into two parts: the power stage and the heating stage. The power required by the pelletizer is directly proportional to the extrusion output and exponentially related to the filter size. Cold pelletizing systems cut pellets from the solidified polymer at the end of the process, while die-face hot pelletizing systems pelletize the molten polymer as it emerges from the die, with the pellets cooled downstream.
