Ceramic Granule Rotary Kiln Introduction

Ceramic stone, also known as ceramic particles or ceramic sand, is a new type of environmentally friendly material. It is a spherical or spherical-like artificial aggregate made of kaolin, bauxite and other minerals as raw materials through crushing, granulation and high temperature sintering.

Ceramic stone it is widely used in the construction field, such as building wall panels, building light aggregate, bricks and other new wall materials. It can also be used to build heat-insulating floor slabs, lightweight concrete, and oil fracking proppant, sewage treatment filter media, refractory materials and other fields, which is an important category of environmentally friendly industrial materials.

The Ceramic Pellet Rotary Kiln is a specialized calcining equipment for the production of high performance ceramic pellets. Ceramic pellets are fed into the kiln through a feed chute and slowly rotated and heated as they move toward the discharge end. The high temperature causes an expansion, sintering or densification reaction to form uniform spherical or spheroidal ceramic particles. The residence time of the ceramic pellets in the kiln can also be controlled by adjusting the rotational speed of the kiln to ensure that the pellets are exposed to the temperature and time required for the particular process.

Ceramic pellet rotary kiln adopts inclined rotating cylinder design, the material is heated uniformly in slow rotation and gradually completes the process stages of dehydration, decomposition, sintering, etc., and finally produces ceramic pellet products with the characteristics of low density, high strength, corrosion resistance, etc. It is widely used in other industries, such as mining, metallurgy and chemical processing, and it has the advantages of low energy consumption, high degree of automation, and stable performance of the products.

Ceramic Granule Rotary Kiln Working Principle

1. The pottery rotary kiln consists of rotary kiln body, supporting device, kiln head and kiln tail sealing device, pulverized coal injection pipe device and so on.
2. The raw material enters the rotating cylinder with inclined arrangement (usually 2-5°) from the kiln tail, and the material moves to the kiln head under the effect of gravity, and then undergoes the three key temperature zones of preheating, calcining and high temperature to complete the densification or expansion reaction, and then forms ceramic particles with specific pore structure.
3. The whole system is equipped with waste heat recovery and exhaust gas treatment device, realizing high energy efficiency and environmentally friendly production.

Ceramic Granule Rotary Kiln Advantages

• Production cost optimization: simple structure, long service life, high efficiency, high heat transfer efficiency, waste heat recovery system reduces energy consumption by 15%-20%, and kiln capacity is increased by 3-5 times.
• Dynamic calcination process: adopting tilting rotating cylinder to make the material continuously turning, receiving heat evenly and avoiding agglomeration.
• Precise control of high temperature: multi-stage temperature zone design, automatic temperature control, over-temperature alarm, secondary air waste heat utilization, long service life of kiln lining.
• Wide adaptability of raw materials: it can deal with a variety of raw materials such as bauxite, fly ash, shale, etc., and realize the utilization of solid waste resources through process adjustment.
