Slag Dryer

Slag processing and utilization requires a slag dryer. Slag is also a major industrial waste produced in steelmaking operations. The industrial application value of slag is relatively high. It can be made into cement, glass, and brick. It can also be used to make agricultural fertilizer or extract useful materials.

Slag Dryer

Brief In Slag Dryer

According to the heat transfer between the drying medium and the wet material, it can be divided into two types: direct heat transfer drum dryer and indirect heat transfer drum dryer. The direct heat transfer type refers to the direct contact between the drying medium and the wet material to transfer heat, and the indirect heat transfer means that the heat required for drying is indirectly transferred from the cylinder wall to the wet material.

The dryer equipment has strong adaptability to materials and can dry various materials, and the equipment operation is simple and reliable. According to different processing materials, it can be divided into coal dryer, sand dryer, slag dryer, gypsum dryer, lignite dryer, sawdust dryer, etc. Users can choose the machine according to their own needs.

Advantages

1. The drying strength is large, and since the material is highly dispersed in the gas stream, the entire surface area of the particles is the effective area of drying.

2. The airflow dryer has a simple structure, a small footprint, and is easy to construct and maintain.

3. The treatment capacity is large and the thermal efficiency is high. When the non-combined water is dried, the thermal efficiency can reach 60%.
