  • 1. Elevator Buckets & Steel Web Belting for use in Cement Elevators PRESENTED BY 4B www.go4b.com www.go4b.com
  • 2. With demand for larger capacity, more efficient and cost effective elevators for handling industrial products such as cement; 4B Components has: Researched and tested products for over 15 years Produced an integrated system composed of 4B Steel Web Belting, Starco Jumbo (SJ) elevator buckets, and designs for compact industrial bucket elevators www.go4b.com
  • 3. What is the SJ System? Replaces traditional chain bucket elevators Replaces large and heavy fabricated buckets in bucket elevators Replaces poor quality steel cord belts on the market with 4B Steel Web Belts www.go4b.com
  • 4. Restrictions of Traditional Systems Use heavy chain and large fabricated buckets Limited number of buckets per meter Max speed of 1.3M/S restricts capacity Chain and sprockets wear quickly High maintenance and replacement costs High capacity requires very large fabricated elevator buckets, therefore larger construction www.go4b.com
  • 5. Starco Jumbo Elevator Buckets Uses 1 to 4 rows of closely spaced heavy-duty Starco Jumbo seamless steel buckets In conjunction with: - Purpose designed steel web high temperature elevator belt Capable of up to 2.3M/S belt speed Achieves far greater capacities per case size than any other system ILLUSTRATION OF STARCO JUMBO BUCKET & STEEL WEB BELT www.go4b.com
  • 6. 4B Steel Web Belt Saves over 40% of component costs Belt wears less than chain Reduces down time and maintenance costs Steel web does not stretch • 0.35% permanent elongation at 10 s.f. • 0.15% unique elastic elongation at 10 s.f. – Allows low pulley crown, avoids drift High elongation at break 5% Guaranteed for 1 year - with lifetime in excess of 7 years Detailed View of Steel Cords www.go4b.com
  • 7. 4B Steel Web Belt Types 4B Steel Web Belts are manufactured in accordance with DIN 22102 and ISO norms and are available in four different types: 1. Type T60 - highly abrasion resistant, maximum ambient temperature 140°F (60°C), cover hardness 60° A shore 2. Type T100 - highly abrasion resistant, maximum ambient temperature up to 212°F (100°C), short peaks 230°F (110°C), cover hardness 64° A shore 3. Type T130 - good abrasion resistance, maximum ambient temperature up to 266°F (130°C) continuous, short peaks 302°F (150°C), cover hardness 66° A shore 4. Type CR - oil and fat resistant, anti-static ISO 284, flame retardant ISO 340, cover hardness 70° A shore www.go4b.com
  • 8. 4B Steel Web Belting Specially Constructed to suit the SJ Buckets and Fasteners, or standard existing steel cord belts Strengths of 800 up to 2500 Kn/m Negligible Belt Stretch - Ideal for Very Tall Elevators, With Very High Capacity Abrasion Resistant Good Bolt Holding Will Withstand Temperatures of up to 130°C www.go4b.com
  • 9. System Benefits Compared to traditional chain and bucket elevators, Steel web belt fitted with Starco Jumbo buckets offer you: Up to double the elevator capacity Throughputs up to 1300 TPH and over Much lower capital investment Longer trouble free life Reduced maintenance and spares cost; Opportunity to upgrade capacity of existing elevators www.go4b.com
