1.The roll is made of alloy chilled cast iron(including separation cast or integrated alloy type).Their surfaces are hard and wear resistance.The rolls are divided into the hollow roll and drilled roll.The hollow roll(hollow roll inner cavity is bored,usually spraying in cavity is adopted for heating or cooling).The hollow roll surface can be machined into smooth roll,whole smooth roll,partial grooved roll,welded up alloy roll and so on.For high cooling or heating speed,circumferential drilled roll can be simultaneously or individually selected.

2.The roll is supported on both end by double row spherical bearings.Large machine adopts double bearing.It has advantages of running smoothly.,energy saving,low noise and long service life.

The base is integral type,the transmission mode is of closed transmission,so it is safe and easy for use.

The user can select the stock blender according to the process.
