Fly Ash Dryer

Introduction

Since wet fly ash has significant characteristics such as large moisture content, small specific gravity, and fine particle size, traditional drying equipment cannot solve the drying problem of wet fly ash. The company’s fly ash dryer realizes large-scale utilization by rapidly dehydrating high-humidity fly ash. It not only solves the problem of environmental pollution caused by fly ash occupation, but also realizes the reuse of waste resources and is favored by the market.

Working Principle

When the hot air temperature of the hot air stove reaches 350°C, under the instructions of the PC system, each equipment starts to work. The wet material conveying equipment sends wet fly ash with a moisture content of less than 20% into the dispersing feeder. The dispersing feeder has dual functions of dispersing and conveying, so that the materials can be sent to the belt conveyor evenly. Then it enters the storage bin, and then passes through the screw feeder to evenly feed the fly ash into the drying drum. This equipment saves one third of energy than traditional tumble dryers, greatly reducing production costs.

Features

1. The thermal efficiency of the cylinder’s self-insulation is as high as over 80%.
2. The fuel can be coal, oil, and steam, and it can dry lumps, granules, and powdery materials below 20mm.
3. The required final moisture index can be easily adjusted according to user requirements.
4. The outlet air temperature is low and the dust removal equipment is used for a long time.
5. There is no need for large and small gears to rotate, and tug wheels are used to rotate.
