(SK) Shearhead

Just before giving the last shape to the rubber compound, shearing strain is applied to it at intervals in order to reach the vulcanization temperature. That interval is between barrel and rotating mandrel.

Mandrel rotating speed varies and can be adjusted automatically to stabilize the mixing temperature. Temperature is measured at output of shearing interval. Temperature is precisely controlled through the mandrel and barrel’s small water cubicles. In order to prevent leakage from mandrel side to the motor, PE film dilution is fed thorough the gap.

The Troester shearing head is equipped with bimetal leak proof materials and PE granule dosing units. Multi-step gearbox conducts the shearing mandrel to be able to adapt itself to the rubber mixing and producing conditions. The Shearing head can be opened easily and taken out together with the mandrel and gearbox from the barrel.
