Planetary extruder

Used Resin

Main Technical Parameter:

Since all toothed components of the machine constantly intermesh, no residual material is left in the machine when changing one formulation to another.

3. Self-cleaning feature:

The optimum heat-exchanging effect created by large contact surfaces of the planetary roller system in conjunction with short residence time of the melt helps to achieve a considerable reduction in formulation costs. Costly stabilizes and lubricants are reduced to a minimum

2. Low-cost Formulation

The planetary spindles, which float in the melt, are retained by a stop ring at the outlet of the extruder barrel. By changing the inner diameter of the thrust ring is possible to influence the residence time of the melt to enhance the effect of dispersion and gelling.

Just one single revolution of the main spindle suffices to roll out the plastic melt and ensuring optimum plasticization, homogenization and dispersion through the intermeshing action of the toothed planetary roller system. Compared with other extruder designs, this system increases the contact surface of the melt by up to five times.
