High-Temperature Resistant Rotary Drum Dryer with 20TPH-5000TPH Processing Capacity and Multi-Stage Heat Exchange

Product Introduction

The refractory material rotary drum dryer is a specialized drying equipment customized for refractory aggregates, refractory powders, high-alumina refractory raw materials, and wet castable materials.

The dryer is optimized according to the characteristics of refractory materials, including high hardness, high temperature resistance, and uneven moisture content. It can efficiently remove surface moisture and capillary water from materials.

After drying, the moisture content of the materials is stable and the texture is uniform, allowing them to be directly used for high-temperature sintering and forming processes.

The equipment is widely used in metallurgical furnaces, refractory products for building materials, industrial insulation material production lines, and other fields. It is compatible with various industrial heat sources and can operate stably under long-term heavy-duty production conditions.

Advantages & Features

1. Heavy-duty and powerful lifting structure
Suitable for refractory materials with mixed particle sizes. It provides thorough material dispersion and prevents accumulation and uneven drying.

2. High-temperature resistant and wear-resistant structure
The complete machine adopts a high-strength design suitable for high-temperature refractory material drying conditions, offering excellent durability and low wear.

3. Multi-stage heat exchange drying process
Provides wide heat transfer coverage and high dehydration efficiency, effectively reducing energy consumption and production costs in large-scale operations.

4. Wide material adaptability
Compatible with various refractory raw materials, including lumps, granules, and powders. One machine can serve multiple production applications.

5. Sealed negative-pressure dust removal system
Effectively recovers fine refractory powder materials, reduces raw material loss, and meets industrial environmental protection standards.

6. Strong and durable overall structure
Features excellent impact resistance, high stability during continuous operation, simple maintenance, and suitability for high-intensity factory production.

Working Principle

The dryer operates with an inclined rotary drum running at a low speed. Various wet refractory materials are evenly fed into the drying chamber.

As the drum rotates, the materials are continuously lifted, turned, and scattered, forming a continuously flowing material layer.

High-temperature hot air passes through the drying chamber and fully contacts the materials, gradually transferring heat and evaporating internal moisture layer by layer.

Under the combined effects of gravity and rotary pushing force, the materials steadily move forward and complete the processes of dehydration and uniform drying.

The qualified dried refractory materials are continuously discharged from the outlet, while moisture-containing exhaust gas is purified through the dust removal system before being discharged according to environmental standards.
