Rotary Dryers for Frac Sand

  1. 1. Experts in process design and material processing for over 65 years.
  3. 3. ABOUT ROTARY DRYERSROTARY DRYERS VS. FLUID BED DRYERS Rotary dryers can process in excess of 300 TPH in a single unit - perfect for the demands of a frac sand drying plant. Rotary dryers are tolerant to variations in particle size distribution and moisture content, producing a uniform product. Conversely, fluid bed dryers are highly sensitive to variations in feedstock. Rotary dryers require less electrical energy than fluid bed dryers, because fluid beds require a high magnitude of air to fluidize the sand. HIGH THROUGHPUT TOLERANCE TO VARIATION IN FEEDSTOCK REDUCED ELECTRICAL ENERGY CONSUMPTION Rotary dryers offer clear advantages over fluid bed dryers when it comes to drying frac sand:
  4. 4. ABOUT ROTARY DRYERSDESIGN CONSIDERATIONS DRUM DIAMETER A number of factors influence dryer performance and product quality. For this reason, the right frac sand dryer design can have a big impact on overall efficiency. FLAME CONTROL AIR VELOCITY FLIGHT DESIGN MATERIALS OF CONSTRUCTION
  5. 5. ABOUT ROTARY DRYERS Lower Nox & CO emissions DESIGN BENEFITS Maintained product integrity Reduced carryover Increased efficiency Uniform results Decreased drying costs
