Energy Saving Industrial Rotary Dryer For Sand Cement Gypsum

Structure of rotary drier

Drier also named as Drying Machine and Rotary Drier.Drier is mainly consist of rotary body, raw material feeding plate, driving and supporting device, etc

Rotary drier :
1. Environment friendly
2. Great adaptability
3. Large capacity
4. Simple structure,etc.

Technical parameters:

Operating principle of rotary dryer:
Wet materials is carried to hopper by belt conveyor or bucket elevator, and added in from the top of feed opening. The cylinder is the main body of the dryer, the material through internal cylinder will contact with the hot air through it in the form of direct flow or reverse flow, or make an efficient contact with the heated wall surface and be dried. After drying, the products will be discharged from the bottom of the other end. In the course of the drying, the materials will move from higher end to lower end in the action of gravity with the help of the slow turning of the cylinder. The cylinder wall is equipped with downstream shovelling plate, which constantly lift the materials and sprinkling it down, so that the heat contact surface of materials is greatly enhanced, improving the drying speed and driving the materials to move ahead. After heat carrier (hot air, flue gas) drying material, the waste gas is evacuated after the carried dust is collected by the cyclone dust collectors. Rotary dryer is one of the oldest and mature drying equipment. The diameter and length of the cylinder is determined by the technological conditions, the size of which reflects the production capacity. The load of the cylinder is mainly determined by self weight of cylinder, the quality of the lining and materials etc.

Working principle of rotary drier
Its principle of operation: the raw material plate which is arranged reasonably with changeable angles in order, throws moisture materials into the rotary cylinder. Then water will be separated from the materials by hot air-flow and changed into vapour to be discharged into the atmosphere. Then the materials would be dried.

Zhongke rotary kiln dryer
It is used for drying materials with humidity or granularity in the industries of mineral dressing, building material, metallurgy and chemical. Rotating dryer can be used for drying many kinds of materials and with convenient and reliable operation; Therefore, it has been widely used.
