Sand Coolers

sand_coolerCarrier vibrating fluid bed sand coolers are designed to cool hot return sand to temperature and moisture levels ideal for mulling.

Three-Stage System

  1. Water Addition
  2. Mixing
  3. Cooling in Fluid Bed 
  • Evaporative cooling process provides maximum thermal efficiency.
  • Fluidization with vibration mixes and turns the sand bed, eliminating hot spots.
  • Because the sand moisture is evaporated while cooling, the cool sand is consistent in temperature and moisture.
  • sand_cooler2Air volume controls regulate and maintain supply and exhaust air volumes at a constant pre-set level to prevent fines entrainment and sand weepage.
  • Continuous plenum discharge incorporates a double seal to discharge weepage sand if loss of supply air should occur.
  • Special hood design minimizes dusting and produces more uniform exhaust velocities.
  • Consistent return sand temperature and moisture content.
  • Minimal maintenance – there are no moving parts in contact with the sand.
