The application of sludge drying machines is becoming increasingly widespread nowadays, but equipment from different manufacturers has its own unique advantages. Many users don't know how to choose and purchase one when making an investment. So, how to choose a suitable sludge dryer?

  When purchasing a sludge dryer, we should consider below factos:

  1. Sludge features: Types of sludge(etp sludge, paper sludge, manure sludge, municipal sludge, wastewater sludge...), and its features (organic matter content, viscosity, whether it has an odor, etc.)

  2. Drying purpose: initial moisture, required moisture content after drying, and the purpose of the dried sludge (landfill, incineration, fuel, fertilizer, or other)

  3. Processing capacity: How many tons of sludge need to be processed per hour? This determines the size and model of the sludge dryer. For example, continuous rotary dryers are suitable for large-scale sludge processing.

  4. Heat source: What can be used as a heat source? Steam, natural gas, fuel oil, coal, biomass fuel, or waste heat from factories. Cheap and stable heat sources should be given priority.

  5. Drying process: There are many types sludge drying process：rotary, paddle, belt, heat pump, disc, etc. The physical properties of the sludge and the required processing capacity jointly determine which drying process should be selected. 

  6. Manufacturer: Choose a sludge dryer manufacturer rather than a middleman, because factory can give you a more favorable equipment price. Furthermore, we should choose a reputable manufacturer, which can ensure the equipment quality and service to a greater extent.
