Refining Roll Mills are in wide spread use in Soap and Detergent industry. Special Chilled casting rolls are employed which rotate in roller bearings. The rolls are interior cooled with water to percolate undesirable heating of the mass during operation. There is continuous water circulation system in all the rolls.
The transfer of soap or detergent mass from one roll to the next is enabled by the differing roll speeds. The first roll gathers up the mass and squeezes it. The second roll runs faster than the first roll as a result of which the soap sticks as a film of adjustable thickness onto the second roll - the rolls possess an accurate manually actuated fine inter roll gap adjustment. The third roll runs faster than the second roll owing to the speeds inter acting rolls both compression and forces act on the inter roll gap and cause an intensive grinding of the soap or detergent mass in small layer thickness. The inter roll-gap between the upper and lower roll can be
adjusted manually.
Capacity :
20 kg/hr. to 250 kg/hr. and above.
Rolling mills usually three but four and five roll mills are also employed for these purpose. The drive is effected via an electric motor and spur gears, pulley and V-belts. Production rate vary with product type, film thickness, moisture content etc.
Capacity :
500 kg/hr. to 2000 kg/hr and above.
