Large sludge drum dryer equipment can be used for textile sludge, printing and dyeing sludge, chemical sludge, electroplating sludge, metal sludge and other high-humidity and high-viscosity sludge. As a professional large-scale dryer, large-scale sludge drum dryer equipment has become an important prerequisite for comprehensive utilization of textile sludge. So, how to ensure the drying quality of large sludge drum dryer equipment?

  1. Control the moisture content during the feeding process.

  The combination state of sludge and moisture is one of the main factors that determines the drying yield. When the moisture content of the sludge is low, less heat source is consumed and the material stays in the sludge drum dryer equipment for a short time, thereby ensuring an increase in the sludge drying yield. Correspondingly, for sludge with large particle size and high moisture content, the drying time is extended and the equipment working efficiency is reduced, resulting in a decrease in the output of the sludge drum dryer. Therefore, when feeding, pay attention to check whether the moisture content of sludge is too high and whether it is within the specified range.

  2. Choose the appropriate sludge drum dryer technology.

  Different drying equipment suppliers use different drying technologies. For example, there are belt type, vertical type, single drum type, double cylinder articulated tooth steam utilization sludge drum dryer, etc. Due to differences in equipment volume and thermal efficiency, the output of different process equipment also varies greatly. Try to choose a sludge drum dryer because the sludge drum dryer equipment is suitable for large and medium-sized sludge drying projects and has the characteristics of strong production capacity and high heat energy utilization.

  3. Properly adjust temperature and air volume

  The working principle of large sludge drum dryer equipment is heat transfer. Therefore, the control of equipment temperature and air volume is one of the key factors affecting the drying quality of large-scale sludge drum dryers. Parameters such as temperature and air volume should be adjusted gradually and not too much at one time. The temperature and air volume should be adjusted within an appropriate range. Parameters that are too large or too small are inappropriate. If the air volume is too large, the hot air will be discharged from the cylinder before it fully contacts the wet mud, and heat loss will increase. If the air volume is too small and the water cannot evaporate, problems such as uneven drying and substandard moisture content will occur.

  4. Choose good equipment structure and technology

  The drying quality of large sludge drum dryer equipment with reasonable structure, mature technology, stable operation and high output should be much higher than that of equipment with backward technology and structure. An unqualified large sludge drum dryer can not only meet the requirements of production efficiency, but also affect the drying quality of sludge.
