Products Description
Bellian Rotary Dryer is a widely used industrial drying equipment in cement plants. It is used for drying various materials with high moisture content such as limestone, clay, slag and coal. Our rotary dryer adopts advanced structure design and high-quality refractory materials, which has high drying efficiency and low energy consumption. It can reduce the moisture content of materials from 20-30% to below 5%, meeting the requirements of subsequent production processes.
Working Principle
The rotary dryer is a slightly inclined horizontal rotating cylinder. Wet materials are fed into the higher end of the cylinder. As the cylinder rotates, the materials are lifted and scattered by the lifting plates inside the cylinder, increasing the contact area with hot air. Hot air enters the cylinder from the lower end (or higher end according to different drying methods) and flows through the materials, evaporating the moisture. The dried materials are discharged from the lower end, and the wet air is discharged through the dust collector.

Buying Guide
When choosing a rotary dryer, you should consider: 1. The required drying capacity; 2. The initial and final moisture content of materials; 3. The type and properties of materials; 4. The available heat source. We will recommend the most suitable model and drying method according to your specific needs.
FAQ
What is the maximum initial moisture content that the dryer can handle?
Our rotary dryer can handle materials with initial moisture content up to 30%. If the moisture content is higher, we can increase the drying temperature or extend the drying time to ensure the final moisture content meets your requirements.
What heat sources can be used for the dryer?
Our rotary dryer can use various heat sources such as coal, natural gas, heavy oil and waste heat from rotary kilns. We can design the heating system according to the heat source you use to ensure the best drying effect.
Is the dryer equipped with dust removal system?
Yes, we can provide a complete drying system including dryer, dust collector, fan and control system. The dust collector can be bag filter or cyclone dust collector according to your environmental protection requirements.
What is the service life of the dryer?
With proper maintenance, the service life of our rotary dryer can reach more than 15 years. The cylinder and supporting system can be used for a long time, while the lifting plates need to be replaced every 2-3 years according to the operating conditions.
