Design and build clay brick tunnel kiln

The investment of kiln and dryer about 60~70% of whole project, we have professional team for kiln construction and supervision, most of the brick project facing problem from kiln and dryer. But we are professional in dryer and kiln.

Tunnel kiln is an advanced and automatic technology in brick making industry.

The features of tunnel kiln are as following:

1. Continuous kiln

A tunnel kiln is a type of continuous kiln that is typically open on both ends and heated centrally. Building materials, such as bricks, may be passed through the device in an uninterrupted fashion, allowing large volumes to be processed without shutting off the kiln between batches.
