Used Rotary and Drum Dryers for sale price

The drum dryer (also called rotary dryer) is used for drying materials with humidity or granularity in the industries of mineral dressing, building material, metallurgy and chemical. Rotary dryer can be used for drying many kinds of materials and with convenient and reliable operation; therefore, the the rotary dryer drum has been widely used. WELLINE is an experienced manufacturer for rotary dryer drum in China with many year experience, and satisfied after-sales service.

Features:

1. High drying strength. Since the materials are highly dispersed in the air, so that the surface of the particles are all the effectively drying size.

2. Short drying time.

3. The structure of the air drying equipment is simple and covers a small size, so that it is easy to set up and maintain.

4. High processing quantity and high heating efficiency. When drying non-integrated water, the heat efficiency can reach 60%.

5. It realizes ‘zero-level pushing force’, thus greatly reducing the abrasion of the supporting wheel and the operation of the cylinder is stable and reliable.

6. This machine adopts “regulating mental supporting device”, so that the combination of the supporting wheel and the roller is always in a linear way, thus greatly reducing the abrasion and movement wear and tear.

Application:

They are widely used in mining, building-material, silicate and chemical industry in the crushing and screening plants. It can be used in a wide application, such as the metallurgical industry, coal mining industry, mining-selecting, building, chemical and grinding industry, etc. As for the feeding materials, Xuanshi's vibrating feeder can put thousands of materials, such as the quartz, feldspar, calcite, talcum, barite, fluorite, rare earth, bauxite, red iron oxide, cement clinker, iron oxide yellow, and compound fertilizer, etc.

Working Principle:

The wet materials are transported into the material hopper by the belt conveyor and bucket elevator, and gets into the feeding terminal through feeding pipe with the aid of feeder of material hopper. The pitch of the feeding pipe should be more than the natural pitch of materials in order to help the materials flow into the dryer machine successfully. The roller dryer is a rotary cylinder which is oblique slightly. The materials are fed from the relatively higher terminal, heat carrier comes in from the lower terminal, and sometimes the heat carrier and materials get into the cylinder together. Along with the revolving of cylinder, the materials move to the lower terminal due to the gravity. When the wet materials move forward, it receives the heat from the heat carrier directly or indirectly. As a result, the wet materials are dried, and discharged out by belt conveyor or screw conveyor on the outlet. There is shoveling plate inside the cylinder in order to shovel materials up and cast it out, to increase the connection surface, to promote drying efficiency, and accelerate the forward movement of materials. Generally, the heat carrier can be hot air and chimney flue.
