PRODUCTION IN THE FACTORY
Anything that can be economically transported by road can be manufactured and lined in our factory. This includes the entire range of a wide variety of plant components such as pipelines, cyclones, hoppers, trough chain conveyors, etc. We would also be happy to repair your worn out components. If necessary, we can also perform any steel metalworking necessary. In this case, you will receive a refurbished, repaired, and surface-treated plant component already equipped with wear protection that is ready for installation. Since we have the most common sizes available in stock, we can deliver a wide variety of wear protection materials at any time on short notice. This means there will generally be enough time available for us to refurbish plant components in our factory during a planned shutdown of the plant.
ON-SITE INSTALLATION
Our experienced, multilingual installation teams install the optimum wear protection lining at the customer site in large-scale and permanently installed plant components such as bunkers, silos, cyclones, or trough chain conveyors. Our employees are available as competent contacts for every technical field. - Immovable plant components and plant components that cannot be transported due to their size or for reasons of cost are lined directly at the customer site. - If desired by the customer, we offer an all-inclusive package: Scaffold construction, sandblasting to prepare the surface to be lined, disassembly, and proper disposal of worn linings - Optional: Supervision to instruct and supervise the customer’s own team of fitters. - Regular checks and maintenance conducted by installation specialists, if necessary, even 24/7 around the clock
DIGITAL SC-LEAK DETECTION SYSTEM
Detecting leaks early and eliminating them promptly are important aspects of project supervision and the cost management of a plant. Even the smallest leaks can cause substantial consequential damage and generate high costs due to production downtimes and the cost of repairs. The Th. Scholten GmbH & Co. KG has developed a highly sensitive leak detection and early warning system in which the ceramic lining in all areas subject to wear are equipped with a signal cable. The outsides of the wear protection lining on the pipes or plant components to be monitored are wrapped with a signal cable. If this cable breaks upon the onset of wear, the sensor system sends a signal via cable or WLAN for the purpose of visualisation. AREAS OF APPLICATION OF THE LEAK DETECTION SYSTEM: - Vessel and plant components that are subject to increased wear and are difficult to access or to monitor - In hazardous areas in which the environment, people, and machines require special protection - Plant components like pipelines, chutes, cyclones, etc., can be monitored.

HARD CERAMIC – WEAR PROTECTION, CONVENIENT AND INEXPENSIVE
The base materials for the manufacture of hard ceramics are high-grade clays, kaolins, feldspars, and pure quartz sand. These materials are finely ground and mixed according to a defined recipe to form a ceramic mass with very high wear resistance properties. The controlled production process safeguards the excellent properties of the hard ceramic, such as: - High abrasion resistance - High compressive strength and resistance to nearly all acids and alkalis (with the exception of hydrofluoric acids and their compounds) - Very good thermal shock resistance - Temperature resistance up to +500°C - Frost resistant and corrosion free - Extremely smooth surface, thus preventing bulk materials from caking, bridging, and clogging
SILICON CARBIDE CERAMIC THE IDEAL WEAR PROTECTION FOR EXTREME CONDITIONS
According to the material classification system for ceramics, silicon carbide ceramic forms part of the group of non-oxide ceramics. Two types are available: - The base materials are high-grade silicon carbide raw materials, silicon dioxide (SiO2), and aluminium oxide - Special quality through a silicon nitride compound (Si3N4) SiC granules are mixed with temporary and permanent bonding agents. They are manufactured in a dry, semi-dry, or compression process. Formpieces are shaped by casting, followed by a sintering process. Characteristics: - Excellent resistance to temperature fluctuations - High temperature resistance - High degree of hardness - High thermal conductivity - Corrosion resistance - Max. service temperature limit, depending on the quality, up to 1.700°C
ZIRCONIA CERAMIC – MANIFOLD APPLICATIONS AGAINST EXTREME WEAR AND HIGH TEMPERATURES
Zirconia ceramic is a material in the group of mixed ceramics and is produced by binding different oxides: aluminium, zirconium, and silicon oxide are molten in an electric arc furnace at approx. 2.000°C. Mixed crystals form, which provide this material with its distinct characteristics: - High strength and hardness - Extremely high wear resistance - 50% Al2O3 content (Al2O3 group of materials) Due to its mineralogical composition – approx. 50% corundum, 32% zircon, and a glass phase content of approx. 18% – and its method of production, zirconia ceramic is frequently referred to as fused corundum, sometimes also as “zirconia-reinforced alumina ceramic”.
ALUMINA CERAMIC – ONLY DIAMONDS ARE HARDER
The term ‘alumina ceramic’ refers to ceramic materials with an aluminium oxide (Al2O3) content above 80%. (Generally, only ceramics with a minimum Al2O3 content of 92% should be used for high-quality wear protection.) Alumina ceramic is one of the hardest technical materials available and is currently the most important member of the group of oxide ceramic materials from a technical and economical perspective. Densely sintered, it is characterized by: - High strength and hardness - High temperature and corrosion resistance
CAST BASALT – OUTSTANDING COST EFFICIENCY DUE TO ITS EXTREME HARDNESS
Cast basalt is a mineral material which, thanks to its special characteristics, is superbly suitable as wear protection: Cast basalt offers the following advantages: - Exceptionally high wear resistance - Unlimited resistance to humidity - High compressive strength and resistance to nearly all acids and alkalis - Full corrosion resistance - Always maintains a smooth and even surface (favourable coefficient of friction for bulk solids) - Excellent price/performance ratio (preventive and economical)
SC-WearStop® – FLEXIBILITY AND EFFICIENCY
SC-WearStop® is a chemically bonded ceramic with the following advantages: - Flexible installation - Very cost effective - Linings without joints SC-WearStop® is mixed just like cement mortar, i.e. with water. Once mixed, it can be adapted to any shape or form within the plant system, directly and individually, by applying it onto a support mesh (diamond mesh). Its technical advantages: 4 material qualities for operating temperatures up to max. 400°C, 3 qualities for operating temperatures up to 1.200°C Flexible layer thicknesses: Through the flexible combination of material qualities and layer thicknesses, we can offer a custom solution for most wear problems Closed surface: In contrast to conventional tiles and formpiece linings, SC-WearStop wear protection is installed without any joints, and therefore does not have any weak points in terms of abrasive wear. Can be easily combined with other wear protection products
