Portoxit® – MIXING TECHNOLOGY THOUGHT THROUGH TO THE END

Advantages of the Portoxit® mixing plant compared to...

...a standard mixing plant

**Flexibility thanks Portoxit^®**
(Standard mixing plants usually only have one function for carrying out screed work, e.g. cement screed mortar, self-levelling screed mortar or cement-bound polystyrene fill.)
**No refilling required**
(Commercially available mixing plants at company premises are usually filled or topped up with cement and sand. Cement is stored in storage silos, whilst sand is temporarily stored in bins, before everything is transported to the building site.)

...a conventional screed mortar mix

**Exact screed grades are achieved – flexibility thanks to Portoxit^®**
(Mixing ratios from 1:4 to 1:8 are possible. If the quantities of cement, sand and water added are inconsistent, the required screed grades are often not achieved and cannot be verified.)
**Reliable, homogeneous mix**
(With a fully automatic, electronically controlled Portoxit® mixing plant, all required screed grades can be reliably achieved.)
**Portoxit^® represents a completely new way of working with screed mortar!**

The mixing process

The state-of-the-art mixing plant features two binder chambers, a sand chamber, a water tank, two tanks for liquid admixtures and a tank for powdered admixtures. The compressor and the generator ensure the plant can operate independently on site. A screw conveyor system feeds the binders and sand into a disc mixer for pre-mixing. The liquid admixtures are added via a feed pump. The formulation settings for the components, tailored to specific requirements (99 formulations possible), are managed via an electronic control system which regulates and documents the mixing and feeding processes. The disc mixer is fitted with a set of scales for monitoring purposes. The compressed air feed chamber is filled via a slide valve in the disc mixer; once filled, it is sealed and the feeding process begins. The disc mixer is refilled whilst feeding is in progress. This enables continuous feeding of screed mortar, taking the mixing time into account.

Disc mixer

In concrete plants, drum mixers are used to produce large quantities of concrete.

• Simultaneous feeding of all aggregates
(sand, cement, water and admixtures)

• Faster and more uniform mixing of the components due to the disc mixer’s larger base area

• Time savings
(With conventional screed mortar mixing and in mixing plants, the aggregates can only be added one after the other. This results in longer mixing and re-mixing times.)

• The binder chambers can be filled using big bags with a crane or a blow-in silo lorry
