Double-drum ceramsite rotary kiln

The double-barreled clay dumbbell kiln is a clay dumbbell kiln technology introduced from abroad by Sucai.“Introduce, digest, absorb and develop”In the spirit of the times, on the basis of the traditional double-barrel kiln of ceramsite in my country, we further integrated and innovated, and successfully developed the advanced double-barrel dumbbell kiln of ceramsite, which completely changed the situation of high energy consumption and low output of the traditional double-barrel kiln of ceramsite, and comprehensively improved the technical and economic indicators of the finished ceramsite products, greatly reduced the cost, and improved the market competitiveness. The output is higher than that of the ordinary double-barrel kiln.30%-50%, energy saving20%-30%. It is especially adaptable to clay and sludge ceramsite.

● The frequency conversion technology is used to make the residence time of materials in the kiln easy to adjust;
● Elastic plate gear transmission and bearing support roller make the equipment run smoothly, reduce power consumption and improve equipment reliability;
● Combined scale seals are used at both ends, and double-pass seals are used at the joints to make the air leakage coefficient less than 8%;
● Use new refractory materials to reduce radiant heat loss;
● The drying and preheating kiln is equipped with a heat exchange device to reduce convection heat loss, greatly reducing the hot air temperature at the kiln tail;
● Support device: It adopts advanced spindle structure and is equipped with automatic temperature measuring device.
● Wheel stopper: It is divided into two categories: mechanical wheel stopper and hydraulic thrust wheel stopper. The hydraulic wheel stopper is equipped with an advanced hydraulic control system.
● Transmission device: single transmission or double transmission. The variable frequency speed motor controls the speed, which is reliable, energy-saving and efficient.
● PLC remote centralized control, easy operation and adjustment, safe and stable

The ceramsite ingredients are fed into the kiln from the kiln tail. Due to the inclination and slow rotation of the cylinder, the materials roll along the circumference while moving axially from the kiln tail (high end) to the kiln head (low end). The fuel is sprayed into the kiln from the kiln head (low end) through the burner for combustion. Heat is transferred to the materials in various ways such as radiation, convection, and conduction. In the process of movement, the materials undergo various physical changes and chemical reactions to meet the technical indicators required by the production process, and are finally unloaded from the kiln head and enter the cooler.
