Due to the special properties as well as the shape of the kiln equipment , gas in rotary kiln has different movement ways with others .ZK CORP will analyze some fundamental ways for you today .

The movement of the gas can be natural or mandatory. Weight differences of rotary kiln gas at various points in the working space generate the force. It causes the gas movement becoming a natural movement, or called natural convection. The movement is without any outside force, and weight differences of rotary kiln gas are usually caused by its different temperature. Forced movement under the action of external force is produced, the external force can be friction sprayed from nozzle, kiln space or unset ends of the pipe pressure difference. In the kiln, (rotary kiln, shaft kiln, etc.) seldom meet a pure natural or forced movement, in most cases, the movement of the gas is produced by the integrative force of the gas itself and the external force.
