Compressed Air Systems should be designed for just the right quality of air at the most economical costs. We have a wide range of dryers for all your needs, for general plant and instrumentation air. Desiccant Dryers, heatless type, use 10 to 15% purge air for regeneration of desiccant i.e. 10 to 15% of compressor power (HP) is being used as energy operating costs for drying thereby increasing the capital costs in installing extra capacity of compressor. They contain two pressure vessels or towers, each containing a quantity of desiccant. One tower dries the air, while the other is being reactivated. The 'heatless' principle of regeneration is based on the physical property of the desiccant, which liberates the adsorbed water vapour, if air with a low water vapour pressure is passed through it.
The mineral slag tumble dryer is mainly composed of hot air furnace, belt conveyor, rotary drum dryer, belt conveyor, induced draught fan, cyclone dust collector, bag dust collector (or wet dust collector) and operation control system. The equipment adopts the fair current (or countercurrent) drying process. Its working principle as following: After entering the drying drum, the wet materials are spitting into the following working areas: First, the material guiding zone. The mineral slag enters this zone and contacts with high-temperature hot air to quickly evaporate water. Under the circumstance of the large lead angle guide plate, it is transferred to the next work area; the second is the copy board area.
