› INTERNAL MIXER with Intermeshing rotors

INTERNAL MIXER with tangential rotors

Internal mixers are suitable for mixing a wide range of compounds. The rotors rotate with a friction ratio between them and they can have 2 or 4 wings. The fill factor of the internal mixer with tangential rotors is higher than mixers with intermeshing rotors.

Applications

Compounding & Mixing

Medical-and-Healthcare Compound for synthetic rubber, compound for natural rubber and thermoplastic in different shapes: strips, leafs, granules; compound for pigment, compound of vulcanizing agents, compound for HCR biomedical grades

INTERNAL MIXER with Intermeshing rotors

Internal mixers with intermeshing rotor are configured with rotors that interface with each other with an intermeshing effect. The two rotors turn at the same speed. The advantages with this solution are:

Better filler dispersion
Higher quality of the final batch
Better thermal control of the batch
Shorter mixing cycle

ROLL MILLS

We offer a wide range of Roll Mills with robust construction suitable for a wide range applications. These mills can be configured with or without stock blenders.
The power transmission system can be configured as single or dual drive in order to better adapt the speed rotation of the cylinders to the viscosity of the rubber compounds

Compounding & Mixing

Conical Twin Mixer

The CTM is a patented mixer of Colmec.
The mixer consists of two counter-rotating conical screws within a conical chamber. The mixer is capable of homogenizing a rubber batch discharged from an Internal Mixer and at the same time guarantee the dispersion of the accelerators added directly in the CTM.
The CTM permits the production of the final rubber compound in a single step. This production can be accomplished automatically without manpower, the traditional Mill is no longer necessary.
