2 Benefit from the consistent use of sophisticated technology and maximise the efficiency of your entire facility! Maximum facility availability, productivity and operating safety guarantee maximum economic efficiency and smooth processes in the entire extraction cycle. Pulley linings of industry ceramic Areas of application General mining Opencast lignite mining Potash mining Salt mining Iron ore mining Gravel and sand pits Cement industry Reliability in the face of enormous loads and for maximum demands The industrial ceramic pulley lining STS 4000 is distinguished by: > high facility availability thanks to minimum down times > high traction, even under loamy-wet conditions > maximum belt utilisation > increased belt life thanks to lower belt tension > significant service life extension of pulley lining and pulley thanks to use of our RenoLin procedure > avoidance of belt slippage and belt over-heating > reduced maintenance and operating costs Conclusion: > avoidance of unforeseeable and cost-intensive down times > securing uninterrupted and highly efficient extraction operation > cost minimisation thanks to lower investment and reconditioning measures > extension of service life by up to threefold compared to rubber linings STS 4000 the ideal solution for belt conveyor systems! Specific application characteristics: > very high friction coefficient > enormous wear resistance > high dimensional stability > outstanding antifriction properties > wide deployment temperature range > thermal, mechanical and chemical resistance > weather-proof > lining repair/-renewal also possible on site thanks to our RenoLin procedure STS 4000 as direct or indirect connection with and without lining base STS Friction offers... The rest of our product range > FRICTION MATERIALS Brake linings Clutch facings Drive linings Holding linings Evolution of the conveying pulleys various diamond patterns > SLIDING, SEALING AND INSULATING MATERIALS depending on specifications. All-wood wood/steel system rubber linings, with and without cermic insets fully ceramic pulley linings STS 4000 for ideal power transmission and maximum operating safety > Evolution - latest development Industrial ceramic STS 4000

3 Pulley linings as good as new thanks to partial or complete reconditioning. Benefit from the unrivalled economy of RenoLin technology! The efficient system consisting of the high performance system STS 4000 and the forward-looking RenoLin pulley relining or reconditioning represents an innovation in economy and productivity. Common diamond patterns Direct repair and reconditioning procedure RenoLin - the innovative high performance procedure from the inventor STS Friction. Only the perfect interplay between the high performance material STS 4000 and the innovative reconditioning procedure RenoLin combined with the decades of on site experience of our technicians in major gravel pits, potash mines and in opencast lignite mining guarantee a 100% result. We would be happy to offer you this viable complete system too! By means of a thermal/mechanical stripping process we achieve a gentle coating removal of the pulley lining STS 4000 produced by us as a direct connection. During the complete removal of the lining no damage or deformation of the pulley surface occurs. The significant advantages in handling are: > complete lining renewal > partial lining repair possible too > 100% material connection at the transition of the repair point > can be performed in the factory or on site at your facility Conclusion: > extension of service life of pulley, lining, belt and as a result of the entire facility > minimum down times, maximum durability > completely reconditioned pulley linings, good as new > low repair costs thanks to partial repair > lining repair depending on access possibility on site too Diamond pattern type H Diamond pattern type D Example of a partial repair on site Diamond pattern type W > gentle thermal/mechanical partial coating removal > STS Friction bonding agent > application, compression and structuring of ceramic mass Without diamond pattern > Innovative repair procedure RenoLin for minimum use of resources

4 Ideal overall solution: and guarantee minimum standstill times, maximum effectiveness and consequently maximum economic efficiency Influence of the pulley lining friction coefficient Preloading Take-up pulley Results Drive pulley Notes: Data basis for the calculation example Conveying length = 740 m Conveying capacity = 720 t/h Conveying height = 120 m Conveying speed = 3,80 m/s Friction coefficients between rubber belt and drive pulleys d L d H T1 to T4 Preloading = conveying length = conveying height = belt tensile forces = required belt preloading force Advantages of STS 4000 in reducing operating and maintenance costs: > service life extension up to three-fold compared to rubber linings > avoidance of belt slippage and belt overheating > extension of belt service life through lining repair or -renovation with RenoLin Advantages of high friction coefficients of STS 4000: Sparing of the conveying belts and as a result extension of belt durability by: > reduction of preloading force by up to 87% > reduction of required belt connection strength by up to 51% > reduction of belt tensile forces by up to 87% > increase in bearings durability through load reduction by up to 87% Types of attachment and design of lining bases/iron pans > Screw connection cylindrical belt pulley > Welding connection Lining base Belt pulley Special truss-head screw crowned belt pulley Edge reinforcement Inner bandage Material key data > Material Pulley lining based on industrial ceramics > Colour Anthracite-grey > Technical data Average friction coefficients - dry: 0,80 µ - wet: 0,60 µ - loamy wet: 0,40 µ Temperature resistance: - 40 C to 120 C Pressure resistance: at RT 30 N/mm² Shear strength lining / pulley at RT 4,5 N/mm² at 120 C 3,0 N/mm² Edge reinforcement Specific weight: 2,0 g/cm³ cylindrical belt pulley Lining base Belt pulley > Design of lining bases / iron pans crowned belt pulley Inner bandage Resistance: Oil, salt, weather > Design 1. Direct connection with pulley 2. Indirect connection with lining base for screwing or welding with the pulley 3. Cylindrical or crowned form in the standard thicknesses 10 mm, 12 mm, 15 mm and special thicknesses from 8 mm at customer request Divison of iron pans Thickness of iron pans Pulley diameter up to Ø315 mm = 2 parts up to 1150 mm = 4 mm Ø315 - Ø630 mm = 2-3 parts mm = 5 mm Ø630 - Ø1000 mm = 3-4 parts mm = 5-6 mm Ø Ø1400 mm = 4-5 parts over 1600 mm = 6 mm over Ø1400 mm = 5-parts + more If so desired other divisions and thicknesses can be made if technically feasible. Edge reinforcements For screwed iron pans For welded iron pans up to 1150 mm = 40 x 4 mm up to 1150 mm = 20 x 4 mm over 1150 mm = 50 x 4 mm over 1150 mm = 50 x 4 mm > Areas of use In rubber belt conveying systems for all kinds of drive, loading and tail pulleys, even under wet and loamy-wet operating conditions. The above-mentioned material key data was determined by STS Friction s test methods. Depending on the specific application, experience shows that the maximum values stated cannot always be achieved simultaneously. Given the multitude of applications, possible uses and technical circumstances, we recommend in specific instances that the material be tested for its suitability in practice. Our consulting engineers and technicians are available for technical questions on your conditions of use. > Innovative technology for convincing drive mechanisms
