During the working, the grinding ball molding line generates many waste burned sand. But most of them can be used again. It needs the sand recycling machine. 

The whole plant parameters and working process

  • Power:three phrase/single phrase:380/220V±15%  50Hz
  • Industrial power: pressure:0.15Mpa, temperature:<200degrees
  • Compressing air:≥0.45Mpa
  • Consumption of air: 22m3/ton
  • Final sand temperature:≦50 degrees
  • Environment temperature:-12~45℃ (real working temperature)
  • The whole process for sand recycling: Waste sand tank→belt conveyor→crusher→bucket elevator→sand bucket→adding material→burning→cooling and dust removing→bucket elevator→sieve→bucket elevator→final sand tank→silicon sand

The whole set of waste sand recycling production line consists of :

sand breaking system, burning system, screening system, recovery system, equipped dust remover system, control system, non-standard steel structure etc.
