GHS Three drum dryer

Introduction

Quartz sand dryer is a rotary dryer, considering the characteristics of Silica sand, the internal structure and raw materials of the mine dryer are improved to meet the special needs of Silica sand production. The equipment is also applied to mine, metallurgy, cement, chemical and other industries.

Three-cylinder dryer equipment can dry dry mortar, yellow sand, cement slag, clay, gangue, mixture, fly ash, gypsum, iron powder and other raw materials, widely used in building materials, chemicals, castings, etc. industry.The three-cylinder dryer improves the internal structure of the original single-barrel dryer, increases the pre-drying of the wet material before entering the machine and prolongs the drying time of the wet material in the machine, plus sealing, heat preservation and reasonable supporting measures to make the dryer dry. Machine production capacity is 48-80% higher than the original single drum dryer.Evaporation intensity per unit volume up to 120-180kg/m3, It has advanced technology, reasonable operating parameters, simple and feasible operation.

Advantages

1. Three cylinder dryer equipment investment is 1/6 of imported products, made of alloy steel plate, 3-4 times more wear than ordinary steel plate.

2. Material can be customized according to demand 304, 316 stainless steel, ultra-pure production, eliminate impurity contamination.

3. The thermal efficiency of the three-cylinder dryer is as high as 80%, and the thermal efficiency is increased by 48%.

4. The three-cylinder dryer reduces the floor space by about 50% compared to the single-cylinder dryer and reduces the civil engineering investment by about 50%.

5. The fuel can be adapted to coal, oil and gas, and can bake blocks, granules and powder materials below 20-40mm.

6. According to user requirements can easily regulate the desired final moisture index.

7. The machine adopts a material and hot air flow drying process,with a wide range of applications

The material is fed into the inner layer of the rotary drum of the three-cylinder dryer by the feeding device to achieve downstream drying.It is continuously copied and scattered under the copying board in the inner layer to achieve heat exchange. Then it  is moved to the other end of the inner layerand enters the middle layer, and the countercurrent drying is performed. Thematerial is repeatedly raised in the middle layer and is entered into two Step by step,The material in the middle layer not only fully absorbs the heat dissipated by the inner drum, but also absorbs the heat of the middle drum, and at the same time prolongs the drying time, and the material achieves the best dry state here.
