Your Professional Industrial Kiln Refractory Solutions Supplier
Our Shandong Luming New Materials Technology Co., LTD is a modern comprehensive enterprise integrating research and development, production, design, construction, and technical services of refractory materials.We specialized in refractory materials for various types of rotary kilns for over twenty years. To address the drawbacks of traditional masonry techniques, we developed an innovative "brick-and-mortar hybrid masonry process" (Patent No.: 201010130626.6). This construction technology has been officially included in China's national《Furnace Construction Manual》.This masonry process innovatively combines the advantages of refractory brick laying and castable monolithic pouring, while effectively overcoming the limitations of both conventional methods.Standardized refractory material design schemes have also been developed for different types of kilns.With field applications in over 100 rotary kilns and continuous iterative upgrades, this solution reliably meets diverse customer requirements. The first-generation technology prioritized operational safety and efficiency, delivering secure and long-lasting rotary kiln refractories that significantly reduced maintenance frequency while maximizing equipment uptime. The second-generation system integrates low-thermal-conductivity materials to achieve 30% reduction in kiln shell temperature and over 10% energy savings while maintaining the safety and longevity advantages. This breakthrough directly supports clients' energy conservation, emission reduction, and green production initiatives.The current third-generation masonry technology and products utilize nanomaterials, achieving safety, longevity, energy efficiency, and environmental sustainability while further reducing the thickness of refractory materials, offering significant advantages in lightweight design.

Types of Lime Kiln
Lime vertical kiln
Lime vertical kiln, as the name suggests, has a vertical kiln body and is a type of lime kiln with a long history and wide application. The structure of the vertical kiln is relatively simple, with a feeding port at the top for feeding limestone raw materials; The bottom is equipped with an ash outlet for discharging the calcined lime. The working principle of a vertical kiln is to decompose limestone in the kiln and generate lime through the heat generated by combustion.
Double chamber kiln
Double chamber kiln, also known as parallel lime kiln, is an efficient and energy-saving type of lime kiln. Its characteristic lies in having two parallel combustion chambers for preheating and calcination operations, thereby achieving efficient utilization of heat and rapid decomposition of limestone.
Rotary kiln
A rotary kiln is a rotary lime kiln with a cylindrical body and a refractory lining inside. Limestone is added from the kiln head, and as the kiln rotates, the limestone is uniformly heated and decomposed inside the kiln. Rotary kilns play an important role in lime production due to their high production efficiency, low energy consumption, and flexible operation.
step-by-step process of Lime Kiln
Step 1. Raw material preparation: Limestone is crushed, screened, and ground to the required particle size.
Step 2. Charging and preheating: Feed the prepared limestone evenly into the preheater. Inside the preheater, imestone is heated to about 900°C by 1150°C kiln flue gas, reaching approximately 30% decomposition.
Step 3. Calcination: The preheated limestone moves along the kiln's axis from the tail to the head, rolling along the circumference due to the kiln's tilt and slow rotation. Fuel is injected through the burner at the kiln head, undergoing combustion. And the heat is transferred to the limestone through radiation, convection, and conduction.
Step 4. Cooling: The quicklime enters a lime cooler where it is cooled to below 100°C using cold air. Subsequently, it is discharged from the cooler.
Step 5. Transfer to the finished product warehouse: The cooled lime is sent to the lime finished product warehouse through the vibrating feeder, chain bucket conveyor, bucket elevator, and belt conveyor. Add screening process according to customer requirements.
Kiln shell
The rotary kiln shell refers to the cylindrical outer structure of a rotary kiln. It is typically made of steel plates that are joined together either through welding or riveting.
Supporting roller
The supporting roller bears the weight of the entire rotating part and provides directional support to ensure smooth rotation of the kiln shell and kiln tyres.
Kiln tyre
The kiln tyre, also known as the kiln ring tyre or riding ring, is a circular steel ring that is placed around the circumference of a rotary kiln and is secured to the kiln shell.
Girth gear
The girth gear is a large gear ring that is mounted on the outer surface of the kiln shell. Its primary function is to transmit torque from the kiln drive system to the kiln shell, facilitating rotation.
Refractory lining
The interior of the kiln shell is lined with refractory bricks or castable refractories. These linings can withstand the high temperatures in the kiln and offer insulation to reduce heat loss. They also protect the kiln shell from the corrosive action of lime and other materials.
