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.
