Introduction
Let’s walk up to the fact of ceramsite. Building ceramsite is a kind of new environmental-friendly material. It is widely used in the construction sector like it can build wall panels, bricks, and other new wall materials. It can also construct thermal insulation floor slab, lightweight concrete, and water treatment and purification. Rotary kiln for ceramsite, as a critical device to produce ceramsite, can directly influences the quality of ceramsite and the cost of production. Rotary kiln drive uses frequency control, which brings high efficiency and low power consumption. Per unit of product has lower energy consumption. Rotary kiln for ceramsite uses negative pressure to reduce dust pollution. The technical process is so simple that it can deal with drying, granulation, and calcination simultaneously. What you need is only a low investment because of rotary kiln’s lightweight and compact layout of equipment. Rotary kiln for ceramsite uses automatic control. It can also make reuse of the warm-up of secondary wind. And advanced seal technology is used in kiln head and kiln tail.
Rotary Kiln For Ceramsite Working Principle
The barrel of rotary kiln for ceramsite has a slope of 3%-4% with a horizontal plane. The kiln body is immobilized in wheel gear by two-wheel band. The principle of rotation is that inverter motor drives the pinion to rotate through reducer and its associated coupling. Then gears mesh with fixed large ring gears in the kiln. Finally, the large ring gears drive the cylinder to make a rotary motion.
Rotary kiln for alumina ‘s drying process is that materials go into kiln through feed pipe. Materials stay rotation with kiln at the same time slip from kiln tail to kiln head because of kiln’s tilt state and slow rotation. The high temperature from calcining kiln is released into drying kiln through connecting devices. Materials are dried through the motion process and be unloaded into calcining kiln from kiln head.
The details of Rotary kiln for alumina ‘s calcining process is below: Burning pipe injects flame. Materials catch heat by radiation, convection, and conduction. After calcining, materials be unloaded to the next process in the kiln head.

Rotary Kiln For Ceramsite Working Process
- Crush and Milling Of Rotary Kiln For Alumina
Extensive materials will be crushed and milled.
- Calcification Of Rotary Kiln For Alumina
After being milled, materials will be put into preheating kiln. The heat source comes from the burner pipe.
- Cooling Of Rotary Kiln For Alumina
Materials are exhausted from kiln heads and be cooled down in a cooling device.
- Selection Of Rotary Kiln For Alumina
Large-size materials will be carried back to the process.

Rotary Kiln Ceramsite Advantages
Rotary kiln for alumina reduces the entry of cold air and the leakage of dust.
The seal among the barrel, active kiln head, and smoke chamber runs well, so it prevents injecting outside air. It stabilizes the thermal system and prevents dust from leaking when processing abnormal operations.
Rotary kiln for alumina adopts a good seal and cooling effect
If cold airflow over into a rotary kiln ceramist’s head, the quantity, and temperature of secondary air will be reduced. So it slows down the burning speed by reducing the cooling effect and the temperature of the flame in the kiln.
Rotary kiln for alumina product with high quality
In the technical process of rotary kiln for ceramsite, the amount of air, fuel, and materials maintain a certain proportional relationship to make sure the reasonable quantity and quality.
Rotary kiln for alumina reduces energy consumption
Rotary Kiln Ceramsite’s tail won’t leak air, which reduces the phenomenon of incomplete combustion and saves energy.
