Focus on heavy equipment
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.

Many mineral processing plants face a confusing problem: even with the same processing capacity, some copper concentrate drying lines consume far more fuel and power than others. The energy gap usually reaches 20%–40% in actual operation. The difference i
Utilizing boiler exhaust gas (120°C–180°C) from a power plant as the heat source for a fly ash dryer is a core strategy for reducing costs in fly ash recovery projects. However, three key issues must be addressed in practice:
Freshly washed sand retains too much surface moisture, unsuitable for direct storage, transportation or end-use processing. For sand production plants, professional sand drying equipment is essential to consistently reduce moisture and qualify finished sa
In the slag processing industry, traditional drying equipment often suffers from issues such as low thermal efficiency, rapid heat loss, and poor sealing, resulting in significant energy waste and high drying costs. In reality, the key to overcoming these
