Principle of slag drying

Technical description of slag drying

1. Scope of application

HG direct heating rotary drum dryer is widely used in food, feed, chemical, pharmaceutical, mining, fertilizer and other industries. According to the requirements of drying products, different heat sources can be used. Such as: direct heating hot blast stove, indirect hot blast stove, heat transfer oil, electric heating, steam, etc. This machine is suitable for drying all kinds of slag materials with water content less than 85%, such as beer lees, alcohol lees, pomace, medicine dregs, water dregs, sauce lees, sugar dregs, starch dregs, poultry manure, slaughter scraps, etc. , It has a good effect on opening up feed resources, reducing feeding costs, and reducing environmental pollution. It is also the most ideal drying equipment for slag drying.

2. Mechanical structure and working principle

The direct heating rotary drum dryer is mainly composed of a heat source, a feeder, a feeder, a rotary drum, a discharging machine, an induced draft fan, a discharger and a power distribution cabinet; after the dewatered wet material is added to the dryer, Under the turning of the evenly distributed plate copying device in the drum, the materials are evenly dispersed in the dryer and fully contacted with the hot air, which speeds up the heat and mass transfer of the drying. In the drying process, under the action of the inclined board and the hot temperament, the material is discharged to the star-shaped discharge valve in the other section of the dryer to discharge the finished product.

3. Main features

1. The drum drying has a high degree of mechanization, a large production capacity, and continuous operation.

2. The structure is excellent and simple, the material runs smoothly through the resistance of the cylinder, and the operation is convenient.

3. Fewer failures, low maintenance costs, and low power consumption.

4. Wide application range and good product drying uniformity.
