Tunnel kiln is much more efficinecy in the clay brick production line .They are mainly matched with large clay brick making machine .

It can meet the customer's request about large capacity .There are many types of tunnel kiln ,you can choose the type as per your need about capacity .

A tunnel kiln is a type of continuous kiln that is typically open on both ends and heated centrally. Materials, such as bricks, may be passed through the device in an uninterrupted fashion, allowing large volumes to be proessed without shutting off the kiln between batches.
The simplest tunnel kiln consists of a single heat source in the middle of the device, with the materials slowly heating and subsequently cooling as they pass through it. More complex versions may be sealed to the outside atmosphere, provide multiple heating and cooling stages, and offer a varitey of interior atmospheric conditions.

The tunnel kiln has a variety of applications across many different industries, but is typically used in large production operations .It may use a moving belt as a method of conveyance through the device, a truck system, a pusher plate, or a number of other options. Regardless of the particular design, the object of the device tends to be to proess a large amount of material in a continuous manner.
