O que é Secador Rotativo?

The single cylinder rotary dryer is designed for drying bulk materials in various industries: building materials, metallurgical, chemical, glass, etc. On the basis of heat engineering calculations, we select the most optimal dryer size and design for customer requirements.

The capacity of the drum dryer is from 0.5 tph to 100 tph. According to the calculations, a loading chamber, a burner, an unloading chamber, a mechanism for dust collecting and gas cleaning are manufactured. The dryer adopts automation system and a frequency drive to adjust the temperature and rotation speed. This makes it possible to vary the drying parameters and overall performance within a wide range.

working principle of a rotary dryer

O princípio de funcionamento de um secador rotativo é baseado na gravidade e na troca de calor. Vamos pegar o secador rotativo de contracorrente como exemplo para explicar o processo:

The wet materials that need to be dried are sent to the feeding hopper by a belt conveyor or a hoist, and then enter the material end through the feeding pipe. The slope of the feeding tube is greater than the natural inclination of the material, so that the material can enter the dryer smoothly. The dryer cylinder is a rotating cylinder slightly inclined from the horizontal line. The material is added from the higher end, and the heating medium is in contact with the material. With the rotation of the cylinder, the material moves to the lower end under the action of gravity. In the process, the material and the heat carrier exchange heat directly or indirectly, so that the material is dried, and then sent out through a belt conveyor or a screw conveyor.
