Furein Machinery is a professional rotary drum dryer machine manufacturer with 34 years of experience. According to our years of market experience and customer material, here is a list of the most common five kinds of diesel rotary dryers: coal slime dryer, sand rotary dryer, fly ash dryer, grain rotary dryer, and poultry manure dryer.
Diesel rotary dryer for coal sludge
The sludge dryer working principle:
The sludge dryer machine mainly dries wet sludge into low-moisture loose material. Diesel fuel dryers are more efficient.
- The feeder feeds the sludge into the dryer and enters the guide plate through the chute. With the rotation of the drying cylinder, the sludge is lifted to the center of the cylinder, forming a material curtain. The high-temperature airflow passes through the curtain, preheating the sludge and evaporating some of the moisture.
- The sludge falls onto the inclined grate-type wing plates, which are in close contact with the preheated wing plates for further heat transfer. The overturning action of the wing plate lifts and sprinkles the sludge repeatedly, increasing the contact area between the material and the hot airflow, and accelerating the evaporation of water.
- The sweeping device buried in the material slides along the inner and outer walls of the lifting plate to remove the material adhering to the plate and play a role in breaking up the sludge ball. After several times of turning and drying, the sludge will be dried.
- After several times of turning and drying, the moisture content of the sludge is greatly reduced and it becomes a loose dry material. The dried sludge is discharged from the discharge port.
Diesel rotary dryer for sand
Rotary sand drier is mainly used for river sand, yellow sand, limestone, quartz sand, clay and other wet, heavy materials, mainly used to dry a certain humidity range of granular materials, such as dry mortar plant used in yellow sand, foundry industry for a variety of specifications of sand.
In addition to using diesel as fuel, sand dryers can also use biomass pellets, electricity and gas. Diesel sand rotary dryer provides a bigger heat source and stronger fire power, people usually prefer to use diesel as the fuel of sand dryer in China.
Furein Machinery's sand drying equipment has a unique advantage in sand dryer, the team has been constantly researching and developing new technology, the most famous three ss rotary dryer originated from Furein. To learn more about sand rotary dryers, please click here.
Diesel rotary dryer machine for fly ash
The diesel fly ash dryer is suitable for drying industrial dust and waste residues such as fly ash and phosphogypsum.
The working principle of the diesel-type fly ash dryer is:
The powdered or granular fly ash is transported to the feeder by the belt feeder, and then the feeder transports the fly ash to the drying drum. The fly ash is evenly dispersed and fully contacted with the hot air under the tumbling of the evenly distributed scrapers in the drying drum, achieving the purpose of heat and mass transfer.
Diesel rotary dryer machine for grain
Diesel grain rotary dryers are mainly used to dry various materials, including corn, wheat, rice, barley, and other grains.
Diesel as the heat source of the grain dryer can accelerate the evaporation of moisture in the grain and dry the grain quickly. Diesel grain dryers can be customized according to your requirements, such as the length, diameter, heat source, etc. of the dryer, and can also be customized grain dryer production lines.
Diesel rotary drying machine for manure
The manure drying plant includes a drying system, a conveying system, an exhaust gas emission system and an electrical control system.
The raw materials in the raw material bin enter the poultry manure dryer through the conveying system, and the dried raw materials are output by the belt conveyor.
The heat source system of the manure dryer can be natural gas, liquefied petroleum gas, methane, diesel or electricity.
The exhaust gas emission system is set at the discharge port of the drying system. The exhaust gas emission system consists of a cyclone dust collector and a chimney. The exhaust gas emission system is particularly important for the manure drying machine.
In the end
All 5 kinds of diesel fuel dryers mentioned above can be changed according to your local energy source, such as electric energy, natural gas energy, etc.
Which energy source you choose can be based on the price of heat source in your market, and choose the lowest one that can make more profit.
In China diesel rotary dryer is the most popular, our Chinese customers like to use diesel fuel rotary dryers because it can help them save more.
