Descriptions:

Sand dryer is referred to three pass rotary sand dryer and is an improved and energy-saving product based on a single tube rotary dryer, used for drying various common sand.

What Is a Sand Dryer?

Sand dryer, referred to three pass rotary sand dryer or three drum sand dryer, is a type of industrial equipment used to reduce the moisture content in sand. This machine is an improved and energy-saving product based on a single tube rotary dryer. The dryer is used for drying common sand, yellow sand, river sand, construction sand, sea sand, garnet sand, slag, clay, and other raw materials. 

The three drum sand dryer is a new type of environmentally friendly and energy-saving drying equipment, in line with the international trend of creating an environment-friendly and resource-saving society. It adopts the latest European energy-saving technology, and clamp type structure. The dryer has a good drying effect.

What Is Sand Dryer Used For?

The primary purpose of a sand dryer is to ensure that sand and other similar materials achieve the desired moisture content. CFTC sand dryer machine is suitable for various applications.

• Construction

• Dry Mortar

• Cement Plant

• Building Materials

• Foundry Industry

• Chemical Industry

• Agriculture

• Water Filtration

• Paint and Coatings

• Glass Manufacturing

• Ceramics and Refractories

What Are the Features of Sand Dryer?

1. Energy saving, the thermal efficiency can be up to 80%.

2. Finished product moisture within 0.5-1% or lower.

3. 20% investment lowered for the same capacity.

4. Adapt to a variety of fuels such as coal, oil, and gas. 

5. Fuel consumption is 30% of conventional dryers.

6. Shortened overall length, space saving, just the 1/3 of a single cylinder dryer.

7. The internal cylinder, middle cylinder, and outer cylinder form the insulation structure. 

What Are the Parts of Sand Dryer?

A triple-pass sand dryer is a complex piece of industrial equipment designed to dry sand efficiently. Here are the main parts of a three-drum sand dryer: inlet, outlet, motor, speed reducer, outside drying chamber, middle drying chamber, inside drying chamber, spring plate, rolling ring, bearing seat, etc.

he most vulnerable parts of the three-drum sand dryer typically include the inner, middle, and outer drum cylinders. They can experience wear due to the constant movement and friction of the sand. The cylinder use alloy steel, with double service life than normal steel.

How Does Sand Dryer Work?

The wet material enters the inner layer of the rotary drum from the feeding device to achieve downstream drying. The material is continuously picked up and scattered under the lifting board of the inner layer, and heat exchange is achieved in a spiral movement. The material moves to the other end of the inner layer and enters the middle layer for countercurrent drying.

The material is repeatedly lifted in the middle layer, absorbing the heat emitted by the inner and middle drums, and the material reaches the best drying state here. The material moves to the other end of the middle layer and falls into the outer layer, and the material achieves the drying effect in the outer drum. The material is discharged from the drum under the action of hot air, thereby completing the drying purpose.
