three roll mill melting, pressurization and homogenization rolls have different and increased speeds from hopper to discharger

 

 

M-200 Artisan is a roll-mill with 3 rolls and their useful length is 700mm. Milling uses two counter-rotating rolls to create a shear stress in the soap, and this type of stress can be considered as a union of different processes: melting, pressurization and homogenization.

The soap must adhere to only one roll in each milling process to obtain a correct shear work, so the rolls have different and increased speeds from the in-feed hopper to the discharge hopper.

 

Gear transmissions are used to rotate the rolls at a particular ratio and the motor used to drive them is 11 kW. The speed of the motor can be changed by a good inverter installed inside the electric panel. Changing the speed of the rolls, it changes the production capacity of the machine.

 

The gap between the rolls can be easily set modifying the position of the external rolls from the central one.

 

A flaker knife is used to detach the soap from the fastest roll. This knife is controlled by a pneumatic actuator that moves the blade only in presence of soap in the machine. The pressure of the blade on the roll can be easily changed by a manual hand-wheel outside the machine.
