Sludge ceramsite rotary kiln Product introduction: This type of rotary kiln is a plug-in double-cylinder rotary kiln. The preheating kiln is used for drying and preheating, and the roasting kiln is used for firing.
Capacity: 50,000-600,000m3/year
Model: Ø1.25×18m-Ø3.0×22m
Processing materials: municipal sludge, river sludge, lake bottom sludge, leather sludge, electroplating sludge, pickling sludge, oil well sludge, coal gangue, fly ash, slag, construction spoil, subway spoil, various polluted soil, etc.

Outstanding advantages of Sludge ceramsite rotary kiln
1. The transmission of the rotary kiln adopts frequency conversion speed regulation, which has high efficiency and low power consumption;
2. Low fuel consumption per unit product, negative pressure operation, and little dust pollution;
3. The technological process is simple, and drying, granulation and calcination are completed at the same time;
4. The layout is compact, the system equipment is light in weight, and the investment is low.
working principle of Sludge ceramsite rotary kiln
The semi-finished granules are fed into the kiln through the chute at the end of the preheating kiln. Due to the inclination and slow rotation of the cylinder, the semi-finished granules roll along the circumference and move along the axial direction from the tail of the preheating kiln to the head of the roasting kiln; the fuel flows from the The kiln head of the roasting kiln is sprayed into the kiln for combustion through the burner, and the heat is transmitted to the semi-finished particles in various ways such as radiation, convection, and conduction. During the movement, the semi-finished particles enter the roasting kiln after being dried and preheated. Roasting, and complete a variety of physical changes and chemical reactions to form ceramsite, which is discharged from the head end of the roasting kiln and enters the cooling machine. The high-temperature flue gas enters the dust removal system at the kiln tail from the end of the preheating kiln
