  2. 2. 2 . WASTE TO MONEY The process of transforming finely divided particles into particles of a larger size by the introduction of outside forces. TECHNO ENVIRO SERVICES PVT LTD *BRIQUETTING*
  3. 3. 3 . Lime Briquetting Useful Industrial Material Recycling Process Successfully Implemented AT VISAKHAPATNAM STEEL PLANT Production Started in 1996 By our Associates AVANI LIME TECH PVT LTD WASTE TO MONEY TECHNO ENVIRO SERVICES PVT LTD VISAKHAPATNAM STEEL PLANT The Briquetting rolls are 18" (457.2mm) in diameter and 6" (152.4 mm) wide, with half-briquette cavities machined into their circumference faces. Calcium Stearate is added as a Binder & Lubricant Briquettes Shape: Almond shape Size along major axis: 50mm Size along minor axis: 25mm Thickness: 20mm

WASTE TO MONEY TECHNO ENVIRO SERVICES PVT LTD Preserves our Natural Resources by Decreasing the demand for Virgin Materials Conserves Energy and Reduces Greenhouse Gas Emissions by Decreasing the demand for Products made from Energy Intensive Manufacturing Processes Save Money by Decreasing Disposal Costs for the Generator and Decreasing Materials Costs for End Users Minimize or Eliminate Dust Improve House Keeping Specifically at BSL, Stop (-) 10 mm Lime going in the Converter Reasons Industrial Materials Recycling
  5. 5. 5 . WASTE TO MONEY TECHNO ENVIRO SERVICES PVT LTD When limestone is calcined in kilns for quicklime 10 to 20 per cent of the stone abrade & emerge as fines Handling and shipping the fines is difficult There are various industrial processes to use fines More practical alternative IS #Quicklime fines into Briquettes# PROBLEM & SOLUTION
  6. 6. 6 . WASTE TO MONEY TECHNO ENVIRO SERVICES PVT LTD Lime briquetting is a process of compaction of lime fines into briquettes of a size similar to the premium product in almond shapes. In this form, the full volume of fines can be reclaimed and used along with the top-quality lime. This can significantly improve plant productivity and cut unit costs by making use of raw material. PROCESS
  7. 7. 7 . WASTE TO MONEY TECHNO ENVIRO SERVICES PVT LTD Binders & Lubricants Binders or Lubricants are additives that increase the strength of the briquette by helping to hold the particles together. Lubricants are mixed into the feed material before briquetting and provide a denser briquette by reducing friction between particles during compaction.
  8. 8. 8 . WASTE TO MONEY TECHNO ENVIRO SERVICES PVT LTD The basic components of a roll-type briquetting Machines are two rotating rolls , with half-briquette cavities cut into the circumference of each. The cavities on opposing rolls match up as the rolls turn, momentarily forming whole cavities as both halves simultaneously pass through the roll centre-line. The Briquetting Machines Loose material is fed between the rolls at their nip region (where the rolls come together), filling the cavities just prior to closure. Pressure applied to the material by the closing of the cavities compresses the materials into a solid mass. As each cavity passes beyond roll center-line, its two halves naturally move apart, allowing the formed briquette to slide out and discharge from the machine.

  11. 11. 11 . WASTE TO MONEY TECHNO ENVIRO SERVICES PVT LTD At Bokaro Steel Plant in the RMP area one Quick Lime Fines Briquetting Plant was commissioned in the year 1990 and due to change in the product mix it is lying inoperative for more than 20 years Lime Fines Briquetting System was Designed, Manufactured & Commissioned by Macmet BOKARO STEEL PLANT Briquetting Plant
  12. 12. 12 . WASTE TO MONEY TECHNO ENVIRO SERVICES PVT LTD PROBLEM Briquetted lime produced had the crush strength less than that of natural pebble lime As a result, briquettes would suffer breakage and disintegration during material handling breaking into powder half way to the user departments , SMS I & II. This exactly what CAUSED the RMP SYSTEM TO FAILURE BOKARO STEEL PLANT Briquetting Plant

  17. 17. 17 . WASTE TO MONEY TECHNO ENVIRO SERVICES PVT LTD PRESENT STATUS OF LIME FINES BSL At present the entire (-) 10 mm quick lime not separated at any stage, thus being fed in the Converters. The fines are generating pollution problem at all the area involved i.e. Lime Receiving Building, Junction Houses, and SMS I & II. There are approximately 100 tons per day (-) 10 mm lime is generated. The Guaranteed generation has been advised of 50 tons . BOKARO STEEL PLANT Briquetting Plant
