High effciency direct heating sand rotary dryer with favourable price
Product DescriptionSand dryer machine adopt rotary drum dryer which is a heat exchange equipment used for drying wet products, it is designed to dry materials of high moisture or strong stickiness, widely be used in the light industry, chemical, food and other industries, such as cassava chips, sludge, sand, coal slime, woodsawdust, cow dung, and other animals dung etc., by direct contact with hot air. The material which is a subject drying is loaded between the furnace and rotating drum drier, and surrounded by hot air, passes through specially developed chambers of a drum.
Features of direct heating sand rotary dryer with favourable price
1. Due to the design of the dryer vanes, managed to increase the heat transfer area and the uniformity of the product drying.
2. Structure for feeding vinasse blades individually in each of the dryer vanes, possible to avoid mixing with the condensed vapor, and greatly increase the drying efficiency.
3. Drying blades more useful to avoid burning the product.
4. On top of the dryer housing consists of double hull. This reduces the hot air flow, reduce heat loss, and strengthen the construction of the dryer.
5. Dryer housing is sealed to provide a sterile product, to ensure cleanliness in the working premises to reduce the noise of the dryer operation.
6. Due to automation, control over the number of the incoming hot air through the exhaust air temperature, automatic control mechanisms, the dryer can be operated 24 hours a day.
Working theory of direct heating sand rotary dryer with favourable price
1.Wet materials are sent to the hopper by belt conveyor or bucket elevator.
2.Materials enter the drum installed with slope to horizontal line from the higher side, and hot air enters the drum from the lower side, and then materials and hot air mix together.
3.The materials was lifted by the equally distributed lifting plate and scattered by the crushing blow dispersion devices on the inner side of drum, in order to make materials and hot air mix completely, which is designed to improve the producing efficiency of rotary dryer.
4.Materials go to the lower side by gravity when the barrel is rotating.
