Coal Rotary Dryer

dry wet coal through hot air to reduce the moisture content of coal and improve combustion efficiency. According to the different physical properties of coal, there are dryers with different structures. For example, for coal slime with many unfavorable drying conditions such as high moisture, high viscosity, high water holding capacity, low calorific value, a new feeding method, a discharging device and a special dispersing device are used , eliminates the clogging, discontinuity, unevenness and material backflow of the cylinder dryer, reduces the load on the dust removal system, and is equipped with desulfurization and denitrification devices, which is green and environmentally friendly.

• After the coal enters the dryer, it enters the following working areas: guide area, cleaning area, inclined lifting plate area, and unloading area.
• The coal enters the material guide area, contacts with hot air and evaporates a large amount of water, and then enters the cleaning area. The cleaning area is equipped with a cleaning device that can quickly clean the coal adhering to the drum wall. The lifting plate in the inclined lifting plate area makes the material form a material curtain state. In the process, it can also break the particle agglomeration, increase the heat exchange area and improve the drying rate.
• After drying, the moisture content of the finished product reaches the standard and enters the final discharging area. The material rolls to the discharge port to complete the entire drying process.
• The reasonable structural design of the supporting wheel and the diversified lubrication methods make the supporting wheel less prone to wear and shaft breakage, shorten the replacement cycle, and extend the service life of the supporting wheel.
• The combination of the spiral guide plate and the new lifting plate increases the fluidity and heat conduction of the material, allowing the material to enter the drying barrel and form a material curtain, which is more adaptable to the moisture and viscosity of the material.
• The dryer system has good sealing performance，Inlet and outlet head adopts special seal to effectively reduce heat loss.
• We accept customization of dryers made of different materials, such as carbon steel, stainless steel, special alloys, etc. Selection of dryer base, dust removal equipment, feeding and discharging equipment, and heat source equipment.
• A variety of heat source equipment, you can choose the most suitable one according to customer conditions,The system is equipped with a PLC system and a video monitoring system, with a high degree of automation and simple operation.
• Provide product quality assurance, with CE IOS certification to compare quality.
