Abstract
A device and method for drying fine particulate. A parallel flow rotary drum dryer is used to dry the particulate material. There is a combustion chamber for the burner, located upstream of the dryer inlet, and the burner flame is limited to the combustion chamber so the fine particulate material does not come into direct contact with the burner flame. The output from the dryer passes through a knock-out box including a baffle system with a plurality of narrow gaps to create a pressure drop to slow down the gas flow and enable the entrained fine mesh dry particulate to drop out through a bottom outlet before the effluent gas is sent to the dust collection/air filtration system.
Claims14
An arrangement for drying small particulate material, comprising:
- a parallel flow rotary dryer, having an inlet end and an outlet end, and defining a downstream direction from said inlet end toward said outlet end, and including a burner and a combustion chamber upstream of said inlet end;
- and
- a knock-out box in fluid communication with said outlet end, said knock-out box including a baffle defining a plurality of narrow gaps through which gaseous material from said outlet end may pass in order to exit said knock-out box.
A method for drying small particulate material, comprising the steps of:
- providing a parallel flow rotary dryer, having an inlet end and an outlet end, and defining a downstream direction from said inlet end toward said outlet end, and including a burner and a combustion chamber upstream of said inlet end;
- and
- providing a knock-out box in fluid communication with said outlet end, said knock-out box including a baffle defining a plurality of narrow gaps through which gaseous material from said outlet end may pass in order to exit said knock-out box.
