Rotary Drum Dryer Furnace

Products Detail

The rotary drum dryer is a cylinder body with a certain inclination angle and adjustable speed within a certain range. The wet material enters the cylinder through the feeder. The inner cylinder is evenly distributed under the turnover of the platen. The materials are evenly distributed and dispersed in the dryer. The purpose of drying is accelerated. The equipment can use a variety of forms of platen. In the drying process. The material is under the action of the platen with inclined angle and hot air flow. Adjustable movement to the dryer another section of the star discharge valve to discharge the finished product.

Raw Materials

It is mainly used in metal powder, coal, phosphate fertiliser, ammonium sulphate, blast furnace slag, mine, graphite, activated white clay, etc.. Widely used in chemical, mining, metallurgy, and other industries. It is used for drying and drying materials with large specific gravity and granular materials. Materials that can be dried continuously in large quantities.  

Advantageous

1. High temperature rapid drying technology, heat transfer coefficient, high drying efficiency

2. High cost performance, fast drying effect, low production cost and stable operation.

3. The distribution and design angle of lifting plate are reasonable, with high heat energy utilisation rate and even drying of materials.

4. hot air and material direct contact, full heat exchange, can meet the needs of different customers

5. Strong expandability, designed to consider the production output, high processing capacity

6. High degree of automation, intelligent PLC control system can be used.  

Technological Process

The heat source of the dryer comes from the combustion unit. The industrial dryer adopts the downflow heating method. Therefore, the material to be dried enters the cylinder from the feed box and feed slip, and is then pushed to the back end by the spiral platen. As the dryer is placed inclined. On the one hand, the material flows to the back end under the effect of gravity and rotation. On the other hand, the material is repeatedly copied by the coping board. The material is brought to the upper end and then continuously spread down. So that the material in the cylinder to form a uniform curtain. Fully heat exchange with the hot airflow in the cylinder. Due to the repeated spreading of materials. The moisture contained in the material is gradually dried. So as to achieve the purpose of drying.
