A municipal thermal power plant wishes to prevent progressive wear in their trough chain conveyor. These units are used to collect and transport away ash and slag from the combustion of e.g. coal under the boiler.
At its largest plant, the world’s leading producer of titanium dioxide has greatly extended the service life of critical piping with Kalenborn abrasion-resistant solutions. Titanium dioxide pigments add brightness and durability to paints, plastics, paper and other everyday products.
One of the largest global producers of building materials relies on Kalenborn solutions at a California cement plant to solve problems of premature wear and clogging on a pneumatic conveyance line for alternative fuel. The plant, which has received EPA Energy Star certification and multiple awards for its environmental-protection and land-stewardship efforts, produces more than 3 million tons of cement annually.
At one of its largest bio-solids recycling plants, a leading company in the biomass industry has specified a trio of Kalenborn abrasion-resistant solutions to extend the life of critical ducting. The state-of-the-art thermal drying facility is part of a joint venture with a major U.S. city and the plant handles all the city’s bio-solids.
KALIMPACT is a hard material hard material rubber composite. Depending on the specific abrasion and impact resistance requirements, KALIMPACT comprises either ABRESIST fused cast basalt, KALOCER oxide ceramics or with KALMETALL hard overlay welded plates. Each of the different material variations is formed into a vulcanised composite rubber sheet.
At a continuous casting plant steel ingots are cast and then cut to appropriate length. Due to the high temperatures, scale develops on the outside of the ingots and is rinsed away in chutes with water to a basin. The scale takes the form of grains some 5 mm in size and causes serious wear in the chutes. Nowadays it has become a standard throughout the world to line such chutes with ABRESIST fused basalt. The smooth surface reduces any deposition of material during transport, as well as protecting against abrasion wear.
In the preparation of iron ore, contaminated surface water travels at high velocity through channels to collection basins. The sharp-edged iron ore is highly abrasive to the concrete surfaces there. Frequent repairs are required as a result. Kalenborn lined the floor of the channels with smooth, wear-resistant ABRESIST fused cast basalt moulded elements. Wear-resistant KALCRET ANX hardening compound was selected to protect the less exposed walls. The combination lining has significantly extended service life and eliminated unscheduled repairs.
