Overview

Adopting a new combination of material lifting and central secondary lifting device, the material has no air holes and high heat exchange efficiency. Multiple circumferential feeding combinations are distributed, effectively controlling drying time and achieving good drying effect. Equipped with a high-temperature flue gas boiling furnace, the combustion is rapid, the heating is sufficient, the thermal efficiency is high, and the coal consumption is less than 15kg standard coal/ton dry material. Integrating heating, drying, and dust collection, achieving mechanization, automation, and meeting environmental protection requirements.

Detailed Introduction

1、 Overview of drum dryer

Drum dryers are widely used in industries such as building materials, metallurgy, mineral processing, chemical engineering, and cement. They are mainly used for materials with high humidity and weight, such as slag, limestone, clay, river sand, quartz sand, and water slag. The slag drying production line mainly consists of a rotary cylinder, induced draft equipment, high-speed dispersing equipment, lifting plate, self-cleaning device, transmission device, conveying equipment, hot air equipment, reducer, support device, and sealing device. The complete set of drying equipment has the advantages of reasonable design, excellent production, stable performance, advanced technology, high output, low energy consumption, small footprint, and high degree of mechanization.

2、 Application scope of drum dryer

A drum dryer is a type of dryer that processes large amounts of materials. Due to its reliable operation, high operational flexibility, strong adaptability, and large processing capacity, it is widely used in metallurgy, building materials, food, light industry, chemical industry, coal, pharmaceutical and mining industries. Rotary drum dryers are generally suitable for granular materials and can also be used to dry sticky paste like materials or materials with high moisture content by partially adding materials. His advantages are high production capacity, wide applicability, low flow resistance, large allowable fluctuation range in operation, and convenient operation. Slag dryer and drum dryer are commonly used for drying sand, mineral powder, coal slurry, chicken manure, cow manure, etc.

3、 Working principle of drum dryer

Dry and wet materials are transported to the hopper by a belt conveyor or bucket elevator, and then enter the feeding end through the feeding pipeline through the feeding machine of the hopper. The slope of the feeding pipeline should be greater than the natural inclination angle of the material, so that the material can flow smoothly into the dryer. The dryer cylinder is a rotating cylinder slightly inclined from the horizontal line. The material is added from the higher end, and the heat carrier enters from the lower end, coming into counter current contact with the material. There are also cases where the heat carrier and the material flow together into the cylinder. As the cylinder rotates, the material moves to the lower end under the action of gravity. During the forward movement of the wet material inside the cylinder, it directly or indirectly receives heat from the heat carrier, allowing the wet material to dry, and then is sent out through a belt conveyor or screw conveyor at the discharge end.

existRotary DryerThere is a copying plate installed on the inner wall of the cylinder, which is used to pick up and sprinkle the material, increase the contact surface between the material and the airflow, improve the drying rate, and promote the material to move forward. Thermal carriers are generally divided into hot air, flue gas, etc. After passing through the dryer, the heat carrier generally needs a cyclone dust collector to capture the materials carried in the gas. If further reduction of exhaust dust content is required, it should be discharged after passing through a bag filter or wet dust collector.

4、 Characteristics of drum dryer

1. Drum dryer has strong overload resistance, large processing capacity, low fuel consumption, and low drying cost;

2. The drum dryer adopts a downstream drying method, where hot air and wet materials enter the dryer from the same side. High temperature air can be used to achieve high evaporation intensity, and the outlet temperature of the dryer is low, resulting in high thermal efficiency;

3. The drum dryer can change its operating parameters according to the properties of different materials, so that the materials can form a stable fully broken fabric curtain inside the dryer cylinder, and the mass and heat exchange is more sufficient;

4. The drum dryer adopts a new type of feeding and discharging device, which eliminates the phenomena of feeding blockage, discontinuity, unevenness, and return of materials in the vertical dryer, and reduces the load of the dust removal system;

5. The drum dryer achieves "zero horizontal thrust", greatly reducing the wear of the retaining wheel and ensuring smooth and reliable operation of the drum body;

6. The drum dryer adopts a "self-aligning supporting wheel device", which ensures that the matching between the supporting wheel and the rolling ring is always in linear contact, thereby reducing wear and power loss;

7. The drum dryer can control the moisture content of the product according to user requirements.
