Transcript

  • 1. Recycling crushing Economical and ecological construction 22.02.2012 JiH
  • 2. © Metso Date Author Title2 Why recycle ? • Recycling Preserve of Nature, Minerals, Environment Nature: - Gravel resources preserved Minerals: - Less consumption of raw materials Environment: - Less transportation need (less fuel) - Less emissions, noise, dust - Amount of waste decreased - Less dumping ground space needed Savings: - Less transportation - No dumping costs
  • 3. © Metso Date Author Title3 The need for recycle crushing is growing rapidly because : • Legislations are getting tighter • Dumping costs are constantly growing • New standards will be developed for the use of recycled material
  • 4. © Metso Date Author Title4 Recycle crushing is becoming good business when : • Dumping of demolition material is expensive • Transport distances are long • Demolition project is situated in a city center • Metal prices are high
  • 5. © Metso Crushing VS Trucking Date Author Title5 Trucking cost 0.03 - 0.06 EUR/ton/km Excavation/Demolition 20000m3 Excavation/Demolition 30000tons Transport cost 30 km 40500EUR Number of loads, 20 tons/truck 2025trucks loads LT1213S production -40mm 150t/h Crushing hours 200hours hours/day 16hours Crushing days 12.5days
  • 6. © Metso Date Author Title6 Case Germany Germany • Dumbing costs 20 e/ton • Selling price 0-45 mm / 5 euros/ton • Scrap iron selling price 150 euros/ton • Factory demolition contract - Contractor will charge 12 e/m3 • Demolition,preparation,crushing • Addtion to that 0-45 mm 5 e/ton • Iron 150 e/ton
  • 7. © Metso7 Recycling crushing process Selective demolition Recycle crushing Sorting Re-use • Such as: - Fill material - Road base and pavement - Asphalt and concrete remixTo be removed: -Too big a re-bars
  • 8. © Metso Typical recycling materials : 8 Concrete Bricks Asphalt Slag • Feed materials and typical products: - Concrete => 0-32/40/50/60 - Asphalt => 0-22 / 0/40 - Bricks => 0-32/40/50 - Slag => 0-22
  • 9. © Metso Recycling crushing with Lokotracks • Feed: Asphalt - 0-22 • LT1110S • LT1213S - 0-40/50 • LT96, LT1110 • LT106, LT1213 - Remark: No compression crushing with asphalt above 10-15° C - Jaw - cone combinations are possible • Feed: Concrete and bricks - 0-32 • LT1110S • LT1213S - 0-40/50 • LT96 • LT106 • LT1110S • LT1213S • LT1315 - Also primary - cone combinations are possible 9
  • 10. © Metso Pre-sorting of the recycling feed material to be crushed • Sorting is crucial for successful recycling operation • Correct size feed material will increase the capacity • Uncrushable materials must be pulled out from feed material • Rebar longer than feed opening must be removed - Max. rebar length about 500mm • Rebar thicker than the minimum setting must be removed - Max. rebar diameter about 20mm • No asphalt recycling above 10-15°C temperatures with jaw crusher. 10
  • 11. © Metso Lokotrack Jaw in Recycling • Jaw crusher advantages: - Economical to crush also abrasive materials - Can be used for very hard and abrasive materials - Different tooth shape for different applications - Recycling (separate the steel from the end product) - Relatively thick rebar can be handled - Coarse end product with a relatively low share of fines - The crushing process can be observed, open cavity 11
  • 12. © Metso Lokotrack Impactor in Recycling • Impact crusher advantages: - High reduction ratio’s - Very high capacity, linear with the power input - Impact crusher can take larger feed than comparable size jaw crusher - Suitable for asphalt recycling at higher temperatures than with jaw crusher - In recycling applications good separation of re-bar from concrete - Good shape of end product - Impact crusher generates more fines than jaw crusher 12
  • 13. © Metso Typical process constraints • Steel from reinforced concrete - Feed material preparation - Magnet separation • Metals in slag - Active setting control • Behaviour of asphalt in warm temperatures - Crushing in winter time - Using support material (mix) 13
  • 14. © Metso Applications for crushed concrete and bricks Crushed aggregate • Crushed aggregate made of demolition waste (concrete and bricks) can be used instead of fresh gravel and rock aggregates for e.g. road base and sub base and foundations of buildings. • Construction with recycled crushed aggregates is no different from construction with gravel or rock aggregates • Good results experienced by using crushed concrete in road base - Better load-bearing capabilities have been measured with thinner layer thickness 14
  • 15. © Metso Applications for crushed concrete and bricks Recycled concrete & Crushed bricks • Recycled concrete - Recycled concrete can be produced out of assorted crushed concrete. - Most of the times crushed concrete is used for frost resistant backfills e.g. as roadbase. - Erosion control Riprap • Crushed bricks - Crushed bricks are often used as backfill material. 15
  • 16. © Metso Use of crushed recycled materials Concrete Date Author Title16 Concrete Quality 0% 20% 50% 100% Recycled aggregate % Demanding application -freezing - erosive -... Less demanding application e.g. foundations, channelworks Typical application
  • 17. © Metso Applications for crushed Slag • Resulting from the separation of a metal from its ore • Slag can be broadly categorized as ferrous (iron/steel) and non-ferrous (copper, lead/zinc) depending on the industry from which they come • During smelting, when the ore is exposed to high temperatures, these impurities are separated from the molten metal and can be removed • The collection of compounds that is removed is the slag SLAG is a product of the steel making process. Before useless byproduct but now accepted as a valuable material in many different applications.
  • 18. © Metso Applications for crushed Slag SLAG is a product of the steel making process. Before useless byproduct but now accepted as a valuable material in many different applications. Main types: Iron blast furnace slag Steel slag Electric arc furnace slag Usage: Replacement 30-50% cement in concrete Road base Asphalt aggregates Concrete aggregates Slag ballast Mineral wool insulation Erosion control
  • 19. © Metso Applications for crushed Slag GGBS = ground granulated blast furnace slag
  • 20. © Metso • Traditionally old asphalt material was only worthless waste - Material consists of - High quality aggregates and expensive bitumen and additives • In modern road paving these valuable materials can be reused efficiently From 10% up to 100% of new asphalt surface can consist of old removed and recycled asphalt • Damaged asphalt surface can be removed with a milling cutter - Waste generated is small in particle size and can be reused as it is • Removal of asphalt surfaces are done by excavators and resulting waste is in form of asphalt blocks - Waste material needs to be crushed before reuse Applications for crushed asphalt
  • 21. © Metso Asphalt crushing with Lokotracks • Typical end products - 0-40 mm (LT96, LT106) - 0-22 mm (LT1110S, LT1213S) • Example - LT1213S - Feed material: Asphalt blocks - Feed size: 0-600 mm - End product: 0-22 mm • Capacity: 220 tons per hour • Compressive crushing (Jaw or cone) cannot be used in temperatures above 10- 15 C • Impact crushing does not have this temperature limitation LT1213 in asphalt recycling
