Industrial coal slime rotary dryer equipment

1.Product Introduction

The Industrial Coal Slime Rotary Dryer is a continuous drying system specifically engineered to process high-moisture coal slime. Its core structure features a horizontal rotating cylinder, which achieves highly efficient dehydration through either counter-current or co-current contact between hot air and the material. As a specialized application of the rotary dryer, this equipment is widely utilized across industries such as coal mining, mineral processing, chemical engineering, and building materials.

2.Application

Specifically designed for high-humidity and high-viscosity materials with moisture content as high as 90%, such as municipal sludge, chemical sludge, electroplating sludge, printing and dyeing sludge, and oilfield sludge. It can reduce moisture content to below 12% in a single drying pass.

3.Working Principle

Coal slime enters from the elevated end of the drum. As the drum rotates, the material is repeatedly lifted and showered by internal flights, ensuring thorough heat exchange with the hot air. Moisture evaporates under high temperatures, and the dried material is discharged from the lower end. To prevent wall-sticking, the equipment often incorporates cleaning devices and a "Zero Horizontal Thrust" roller structure, which minimizes wear and enhances stability. The drying process is typically divided into multiple temperature zones (e.g., from 430 C down to 60 C), achieving high-efficiency
dehydration while preventing the coal slime from coking or charring.

4.Advantage

1. High Capacity & Low Energy Consumption
By integrating co-current and counter-current drying methods, the system achieves high thermal efficiency. The final moisture content of the product can be precisely controlled to below 8%.

2. Strong Adaptability
The equipment is highly versatile and capable of processing a wide range of high-moisture materials, including coal slime, slag, sludge, and clay.

3. Stable Operation
The self-aligning support roller design significantly reduces vibration and component wear, ensuring reliable and continuous long-term operation.

4. Environmental Compliance
Equipped with a high-efficiency dust collection system, the flue gas emissions strictly adhere to international environmental standards.
