The JUPITER dry levelling compound is suitable for levelling uneven substrates from between 10 and 60mm and filling voids up to 150mm deep.

 

Description

Our unique, dry-installed floor levelling compound provides a rapid floor levelling solution that introduces no moisture to the build process.

​

The slate compound undergoes a kiln drying process  that renders it thermally inert and which imparts a tight honeycomb structure to the slate.

​

It is this special structure which means that Jupiter’s slate levelling compound mechanically binds under load and, unlike sand blinding, will not dissipate through repeat pumping action as the floor is walked on.

Manufacturing process

The clay slate is rough-crushed, sieved and subsequently broken by means of various crushers down to the specified grain size of 10 to 80 mm. The grain of specified size is stored as feeding material in silos. From here it is lifted via a crusher and supplied to the rotary drum furnace by means of conveyors. Inside the rotary drum furnace, the clay slate is heated up using a carbon powder flame working on the counter current principle to approx. 1,159° C, i.e. until a pyro plastic condition is reached. The gases resulting from the burning of organic clay slate components as well as the separation of oxygen from the natural ferric oxide to be found in the clay slate allows for the swelling of the slate. The resulting swelled coarse grains have now taken on a honeycombed cellular structure full of tiny pockets of air. The swelled slate is cooled down in a cooling drum. At the same time, the combustion air drawn in via the cooling drum is heated up for the rotary drum furnace working on the counter current principle to 400°C to 500°C. The coarse swelled slate is fed via conveyor belts to two roll type crushers and cut up. After passing two crushers, the crushed material is sieved and separated by shaking screens into sieve fractions.
