What's the difference between tunnel kiln and roller kiln?

It is a continuous production kiln. Tunnel kiln needs a trolley to carry objects, and the trolley needs to be heated together, which will disperse some heat and cause great heat loss.

The roller kiln type Liyong roller table rotates to transfer the object, and the heat directly acts on the object, making the residual heat of the product more uniform. Colleagues save energy.
