What is the difference between a double wrist granulator and a single axis granulator?

There are significant differences in structure and function between dual wrist granulators and single axis granulators.

Structural difference: The dual wrist granulator has two rotating arms that can perform both granulation and cutting operations simultaneously. The single axis granulator has only one rotating axis, which is used for granulation through extrusion and cutting mechanisms.

Functional difference: The dual wrist granulator can perform granulation operations in both directions simultaneously, with higher production efficiency. The single axis granulator can only perform granulation operations in one direction, resulting in relatively low efficiency.

Production capacity difference: The production capacity of the double wrist granulator is relatively large, which can meet the needs of large-scale production. The production capacity of a single axis granulator is relatively small, making it suitable for small-scale production.

Applicable material difference: The double wrist granulator is suitable for granulating various plastic, rubber and other materials. The single axis granulator is suitable for granulation of certain plastic, rubber and other materials.

Energy consumption difference: The energy consumption of the dual wrist granulator is relatively high because it requires driving both rotating arms simultaneously. The energy consumption of a single axis granulator is relatively low, as only one rotating shaft needs to be driven.

Differences in operating difficulty: The operation of the double wrist granulator is relatively difficult and requires a higher level of skill. The operation of the single axis granulator is relatively simple and suitable for beginners to operate.

The difference in production capacity between double wrist granulators and single axis granulators is mainly manifested in the following aspects:

Yield: The yield of a double wrist granulator is usually higher than that of a single shaft granulator. Due to the dual wrist granulator having two rotating arms, it can simultaneously perform granulation and cutting operations, thereby improving production efficiency. The single axis granulator only has one rotating axis and needs to process the raw materials one by one, so the output is relatively low.

Production speed: The production speed of the double wrist granulator is also relatively fast. Due to the fact that the two rotating arms of the dual wrist granulator can work simultaneously, more raw materials can be processed per unit time. The production speed of a single axis granulator is relatively slow because it can only perform granulation operations in one direction.

Applicable material scope: double wrist granulator is suitable for granulation of various plastics, rubber and other materials, such as foam plastics, rubber and so on. The single axis granulator is suitable for granulating certain plastic, rubber and other materials, such as PP, PE, etc.
