Product Introduction

As a new type of environmentally friendly material, construction ceramsite has been widely used in the construction field. It can be made into new materials such as wall panels, floor slabs, and lightweight concrete, and can also be used for insulation, heat preservation, water treatment, and purification. The rotary kiln, as a key equipment for the production of construction ceramsite, directly affects the quality of the finished ceramsite and production costs.

Application Fields

Mainly used for roasting materials such as sludge, clay, fly ash, shale, coal gangue, contaminated soil, and construction waste soil in the construction ceramsite industry.

Outstanding Advantages

1. The rotary kiln drive adopts variable frequency speed regulation, which is highly efficient and has low power consumption.

2. Low fuel energy consumption per unit product, negative pressure operation, and low dust pollution.

3. Tire device: After vibration aging treatment to eliminate welding stress, it can improve the installation accuracy of the entire machine.

4. Compact layout, lightweight system equipment, and low investment.

Working Principle

Semi-finished particles are fed into the kiln through the tail chute of the preheating kiln. Due to the inclination and slow rotation of the cylinder, the semi-finished particles roll circumferentially while moving axially from the tail of the preheating kiln to the head of the roasting kiln. Fuel is sprayed into the kiln from the head of the roasting kiln through burners for combustion. Heat is transferred to the semi-finished particles by radiation, convection, conduction, and other methods. During movement, the particles undergo drying and preheating, then enter the roasting kiln for roasting, completing various physical changes and chemical reactions to form ceramsite. The ceramsite is discharged from the head end of the roasting kiln into the cooler. High-temperature flue gas enters the tail dust removal system from the tail end of the preheating kiln.

Architectural Lightweight Aggregate Rotary Kiln

The rotary kiln for producing lightweight ceramic pellets is the core equipment used to sinter clay, shale, or industrial solid waste (such as fly ash) into porous pellets at high temperatures. Its main body is a sealed steel cylinder (the double-row inclined silvery main body shown in the picture), lined with high-alumina siliceous refractory materials to withstand the high temperatures and mechanical wear during the sintering process. The cylinder is supported at a 3°–5° incline by roller devices and driven by a transmission system (visible motor and gear set in the picture) to rotate slowly at 1.5–3.5 r/min. Materials are added from the high end at the kiln tail, while hot gases are introduced from the low end at the kiln head. The incline and rotation enable counter-current heat exchange, completing the preheating, sintering, and cooling processes.
