This pump is a reliable and durable solution for marine and industrial water pumping needs. If you have any specific requirements or questions, feel free to contact us for further assistance.
Material is fed into the machine from feeding inlet, and moves forward continuously along with the level of fluid bed under the action of vibration force. Hot air passes through fluid bed and carries out heat exchanging with damp material. Then the damp air is exhausted out by exhaust fan, some fine powder is collected by cyclone separator and dust remover, and dried product is discharged from discharging outlet.
