Product introduction

The drum dryer is a kind of dryer, which belongs to building materials equipment. It is used to dry materials with a certain humidity or particle size in the mineral processing, building materials, metallurgy, chemical industry and other departments, such as slag, limonite, gold ore, fly ash, coal slime, lignite, hematite, talc, limestone, clay and other materials. The center of the drum dryer can avoid adding a dispersing mechanism. The wet material that enters the drying cylinder is repeatedly picked up and thrown off by the copy plate on the drum wall, and is broken into fine particles by the dispersing device during the falling process. The area is greatly increased, and it is fully in contact with hot air and dried.

Working principle of drum dryer

The heat source of the drum dryer mainly comes from the combustion device inside the machine. The wet material that needs to be dried is sent to the hopper by a belt conveyor or bucket elevator, and then enters the feeding end through the feeding pipe through the feeding machine of the hopper. The inclination of the feeding pipe should be greater than the natural inclination of the material so that the material can flow smoothly into the dryer. Because the drum of the tumble dryer is a rotating drum slightly inclined to the horizontal. After the material enters the cylinder, it is added from the higher end. The heat carrier enters from the lower end and contacts the material in a countercurrent flow. There is also a co-current flow of the heat carrier and the material into the cylinder. With the rotation of the cylinder, the material moves to the lower end by gravity. The copy board on the inner wall of the cylinder picks up and scatters the materials, which increases the contact surface between the materials and the airflow, so as to increase the drying rate and promote the advancement of the materials.

Drum dryer performance advantages

1. The drum dryer adopts a new type of multi-combination lifting device, which overcomes the "wind tunnel" phenomenon of traditional dryers, has high thermal efficiency, and effectively reduces coal consumption by about 20%.

2. The blocking wheel structure specially designed by our company for the drum dryer greatly reduces the horizontal thrust caused by the inclined work of the equipment, has strong anti-overload ability, stable operation of the cylinder and high reliability.

3. There is no air leakage, the difficulty of sealing is completely solved, and the installation can be completed within 2 hours; in addition, the thermal efficiency of the equipment is as high as 80% (the thermal efficiency of the traditional single-tube dryer is only 32%) and the thermal efficiency is increased by 48%.

4. The drum dryer is highly adaptable to materials, can dry various materials, and the equipment is simple and reliable to operate, so the dryer equipment is widely used.

Drum dryer price

Because different types of drum dryer equipment have large gaps in raw material materials, technical content, production costs, etc., the equipment selection is different, and the price is naturally different. The price of the specific drum dryer still depends on the specific tumble dryer model purchased by the customer. Zhengzhou shuguang machinery has been focusing on the production of mining equipment for nearly 30 years. The drum dryer equipment has mature manufacturing technology, complete models, complete supporting facilities and reasonable prices. What is the specific price of drum dryer?
