Clinker tile manufacturer, CC Hgans, lies on top of a 200 million-year-old clay deposit in southern Sweden. It is an area with a mining industry that dates back to the 16th century, when many smaller companies in this region began extracting coal from the ground.In 1886, CC Hgans decided to start clinker tile production from the clay that was originally viewed as waste by the coal miners because it was situated between layers of coal. The company soon grew a good reputation for the high quality of its clinker tiles.Today, CC Hgans is part of the Ricchetti Group, a world-leading supplier that manufactures tiles in five countries.CC Hgans amazed by Barmac crusherThe modern production plant in Ekeby, Sweden, crushes the scrap clinker that does not meet specification in a iPod Accessories seven-year-old Barmac B3000 Vertical Shaft Impactor (VSI) crusher.We were looking for a machine that could replace our existing Rod Raymond Mill, which was very expensive to operate. The new machine would help our existing Jaw crusher and 30-inch cone crusher in crushing our scrap tiles down to 0-1.5mm, says Ove Paulsson, Production Manager at CC Hgans in Ekeby.After the initial lab test it was clear the Barmac, with its rock-on-rock crushing principle, would achieve the result Hgans was looking for.It was quite amazing really, says Ove Paulsson. I was present at this lab test and I went out for a while, expecting the crushing to take several hours. When I came back into the lab after a few minutes, the Barmac was finished crushing the clinker we had brought with us!The Barmac has worked wonders for us, says Ove Paulsson, Production Manager at CC Hgans.Recycling saves raw materialsThe required capacity called for the smallest machine model in Metso Minerals' Barmac VSI range, the B3000. The Barmac was installed in the crushing plant in closed circuit with Mogensen sizers. The feed material is 020mm coming from the 30-inch cone, which can now operate at a closed side setting far more suited to its mechanics.The final product of the circuit is 0-0.5mm and 0.5-1.5mm. The plant has a built-in flexibility, which allows for re-crushing Wholesale Tissue Box Covers of 0.5-1.5mm in the Barmac. The gradation is important when mixing the Barmac product back into the virgin clay to make new clinker tiles. Therefore it is important to be able to produce the right mix of flour (0-0.5mm) and 'grains' (0.5-1.5 mm)The capacity for the Barmac B3000 VSI is a moderate 8-10 tonnes per hour. However, the same crushing result could easily be scaled up in any of the bigger models.The Barmac has worked wonders for us and one thing that came as a bonus was the fact that it does not contaminate the product with any metal from wear parts, Ove Paulsson goes on to say. "Metal contamination is unwanted both from an aesthetic and functional point of view. The principle of the Barmac is really quite beautiful in its simplicity. The machine lets the material crush itself, so the metal from the mill rods that we had to Wholesale Pneumatics separate before is no longer a problem."Ove Paulsson also adds: By being able to recycle tiles, we save on both raw materials and also on expensive colouring pigments, like cobalt for our blue tiles.New tiles for the Sydney Opera HouseWhen Danish architect Jrn Utzon designed the Sydney Opera House in 1957, he did not have to go far to find the building material he was looking for. He chose the CC Hgans clinker tile to cover the 16,000 square metre surface of his unique design.Since then, the Sydney Opera House has become one of the worlds most famous buildings and the tiles from Hgans still contribute to its beauty 40 years on.Ove Paulsson offers up a scrapped tile from the Sydney range that is just about to be crushed in the Barmac circuit. Naturally, CC Hgans takes great pride in the fact that their tiles, sitting on the roof of a world famous building on the opposite side of the planet, are still in great shape.An inquiry has recently come in from Sydney for new tiles for the Opera House. This means material produced in the Barmac VSI crusher will soon be covering the roof of the Opera House.Ove Paulsson finishes by telling us that the Sydney tile is still available today, should you be thinking of redecorating your bathroom at home.
