2. Roll f200mm drawing No. TM 1646.01.000 – 18 pcs.
3. Roll f250mm drawing no. MVP-023.02.000 – 18 pcs.
4. Roll f300mm drawing No. TM 1646.02.000 – 18 pcs.
5. Roll f370mm drawing no. MVP-023.03.000 – 54 pcs.

The rolls are installed in a centrifuge (fiber forming machine). A melt of stone raw materials is fed to the rolls at a temperature of 1500 degrees. Celsius. The task of the roll is to unwind the melt to the state of a fine hair at a rotation speed from 3000 to 6000 rpm. The roll has a hollow shape and is cooled inside with running water. The main indicator of the quality of the rolls is the exact execution according to the drawing of the welds, the end and axial runout in the tolerances of the drawing.
The centrifuge unit is one of the main units of the mineral wool production line. An emergency failure of the roll may result in the failure of the centrifuge itself, the spindle assembly, emergency unloading of the line and loss of raw materials.
