The rubber industry depends on water to cool various types of equipment. But where there’s water, there’s water-related problems caused by mineral deposits. These deposits are causing manufacturers varying degrees of water-related problems, affecting operating efficiencies and leading to other, more costly problems including downtime.
Mineral deposits accumulate quickly regardless of screens or treatment. Even a thin coating of water scale will act as insulation and eventually retard the transfer of heat in water systems; an example of this is scale inside a mill roll causes hot spots, thus producing inferior rubber production quality. You can put an end to your water scale problems with ScaleAway Descaling Solution, a safe and environmentally acceptable alternative to other scale removal methods.
Instructions for Cleaning of Banbury Mixer
When water scale, lime and rust deposits accumulate on the water side of jackets, rotors and the gates of the Banbury Mixer, it causes high stock temperatures and a
loss in production.
In order to remove these deposits:
- Take mixer out of service.
- Close water supply valve at header.
- Drain all water from all sections of mixer.
- Connect ScaleAway’s System Descaling Cart'sTM pump discharge hose to water
header. Header usually supplies all circuits.
- Connect return hoses to drain lines from all circuits and
place into the ScaleAway’s System Descaling Cart'sTM receiver.
- Close water supply valves to gate and jacket circuits.
- Start pump and pump the ScaleAwayTM descaling solution into rotors to purge
the water from this circuit to sewer. When the ScaleAwayTM descaling solution begins to discharge from this hose, return to the receiver.
- Open water supply valve to gate and maintain ScaleAwayTM descaling solution circulation through this circuit.
- Open water supply valve to jacket and maintain ScaleAwayTM descaling solution circulation through this circuit.
- If any circuit is NOT flowing properly, restrict ScaleAway Descaling Solution flow in other circuits until flow returns to normal in this circuit.
- Circulate a total of 120 Litres of ScaleAwayTM descaling solution through all circuits of mixer until clean. This will require approximately four (4) hours pumping time (depending on amount of scale build-up).
- It is suggested to periodically rotate the rotors during ScaleAwayTM descaling solution cleaning to assure that the ScaleAwayTM descaling solution is in contact with all of the lobes of the rotor.
- Upon completion of cleaning, flush all ScaleAway Descaling Solution from all circuits with fresh water.
- Disconnect the ScaleAway System Descaling Cart’s pump and all hoses. The mixer is now ready to be returned to service.
Periodic descaling will keep the temperatures of the mixer within acceptable limits, assuring you a better product and minimize burnt or improperly mixed stock.
- Clean out the ScaleAway System Descaling Cart and store for future use.
The tire and rubber industry has a great variety of uses for water and each may have its own quality requirements. ScaleAwayTM descaling solution can be utilized in virtually
any area of your facility.

By incorporating ScaleAway'sTM descaling solutions into your preventive maintenance program, you can keep your equipment running effectively and economically.
A large rubber manufacturer in Isando was experiencing high stock temperatures and loss of production in a number 11 Banbury
mixer. A total of 120 Litres of ScaleAwayTM descaling solution was circulated through the jackets, rotors and gate for only
4 hours, then water flushed and returned to service, well within operating limits. The cleaning resulted in better stock and
minimized burnt or improperly mixed stock. The customer was astonished at how safe, economical, rapid and effective
ScaleAwayTM descaling solutions performed on his fouled equipment. ScaleAwayTM descaling solutions are now an integral part of
their maintenance procedure.
Listed below are just some of the types of equipment that can be thoroughly cleaned with ScaleAway's descaling products
