Sicon
The enclosed belt conveyor for the cement industry

Makes a clean sweep of environmental and transport problems

A superior transport system!

Sicon has a worldwide experience from the cement industry.

Strict demands on the working environment and on the industrial process, require the cement industry to choose the most efficient conveyor systems.

Today Sicon conveyors solve difficult transport problems. From raw materials to the end products.

Limestone
The Sicon closed conveyor takes care of the transport as well as of the dust problem for Cementa AB in Sweden and Kalkzandsteenfabrik Harderwijk in Holland.

Sand
Spillage problems of salty ocean sand, absorbing moisture from the air and sticking to the open return part of ordinary conveyors, are eliminated by Sicon's enclosed return part at Cementa AB in Sweden. Sicon also handles sand at Kalkzandsteenfabrik Harderwijk in Holland and Phoenix in Germany.

Chemical gypsum
At Alsen-Breitenburg in Germany and Ellcraft in Denmark spillage problems from moist gypsum are eliminated.

Fly ash
No dust problems arise if the fly ash is transported in a dry state. If wet, like at ECNSWin Australia, there is no problem of material sticking to the return part. Thanks to Sicon's enclosed return part.

Coal and pyrite
The closed conveyor takes care of the dust problem at Unicem in Italy.

Cement clinker and cement
At Cementa AB in Sweden, the belt for cement clinker is made of a special rubber compound resistant to temperatures up to 900 C. The belt conveyor can be provided with temperature sensors.

Raw material substitutions and hazardous wastes for incineration.
 Aalborg Portland in Denmark, installed Sicon for conveying of paper residue and Alsen-Breitenburg in Germany, installed Sicon for oilcontaminated soil. Installation requires a minimum of interference with the buildings of the plant. In both cases the enclosed conveyor protects the working environment.

Within Sicon's range there are few alternatives!
 It is the enclosed handling, the limited dimensions, the ability to run around sharp corners and the elimination of all transfers that make the Sicon belt conveyor so uniquely suitable for the cement industry!

No wonder the cement industry was the first to see the advantages of Sicon!

The very first Sicon conveyor was installed at a cement factory.

Some years ago Sicon assisted the largest cement producer in Sweden in eliminating the dust and spillage problems related to the transport of sand and limestone from the stockpile to the buffer hoppers at the mill. This was the very first installation of a Sicon conveyor.

Dust and spillage. A major problem in the cement industry.
 Before the installation of the Sicon conveyor, no less than four conventional belt conveyors, connected via transfer chutes, were used to handle the transport. The total length of transport was 270 meters. Great amounts of spillage were accumulated under the conveyors. There were also dust problems at the transfer points.

The solution: One single, enclosed conveyor with no transfers!
 Sicon installed its new and uniquely enclosed belt conveyor. It can negotiate very sharp corners without the need for any transfers. A new covered gallery was built for part of the distance. For the remaining distance, existing buildings and structures were used to run the Sicon conveyor the shortest way between the loading and discharge points.

The result was one enclosed conveying system, covering the whole transport without transfers. The distance was 20 meters shorter, and the new conveyor also used much less space than conventional belt conveyors. Above all, the client enjoyed transport entirely without dust problems and spillage (see drawings).

A superior solution!
Sicon was the sole conveyor to solve all the problems in one single conveyor. One single conveyor from loading to discharge.

No transfers! No dust! No spillage!

New Interesting Application!

Kiln-burning. The perfect answer to environmental problems.
The enormous amounts of hazardous waste in society not only create environmental and handling problems - in many cases they are also an untapped source of energy.

Much of the hazardous waste can be safely burnt in the kiln. Environmental agencies in the USA have no data to support that emissions and residues from the burning of hazardous waste in cement kilns pose any threat to health or the environment.

Documented energy savings.
Reports from the USA show that up to 40% of the kiln energy requirements can be met using solid waste derived fuel.

The primary technical obstacle is physical handling.
 How can the cement industry collect, process, transport and convey different types of waste to the appropriate delivery point in a cement kiln?

Sicon solves the transport and convey problem!
 Sicon encloses the refuse, protecting the environment all the way up to the kiln. The temperature problems on the last stretch can be solved by means of a screw conveyor.

Sicon advantages are obvious:
