1. The open mill is a two-roller machine, which uses two rollers with different rotational speeds to produce shear force to masticate. The operation is to continue the operation of the triangle package. The internal mixer produces shear forces by utilizing the regular contraction of the space created by the internal designed blades.

2, open mill (open rubber mixer) by manual glue, each batch of each rubber mill is different, the refined glue is unstable; open mill structure is simple and low cost, but labor intensity, pollution Big, it hurts the worker's body. Mixer (closed rubber mixer) machine mixer, stable, efficient, high productivity.

3. The structure of the open mill is simple and easy to clean; the structure of the mixer is complicated and difficult to clean.

4. The open mill is unsafe and exposed to the outside; the mixer is safe and closed.

5, the open mill heat dissipation is fast, not easy to die; the mixer is not easy to dissipate heat

6, the open mill can produce film, the mixer can not produce film

7. The open mill is cheap, the mixer is more expensive, but it can be heated, vacuum can be used, and the pressurizing mixer can be used to process materials that are difficult to plasticize. Labor intensity is low and adaptable.
