In addition to the feed and the material is provided due to the out of the kiln needs kiln entrance, the kiln side provided with an observation hole, and detecting holes, without any holes, closed tight and reduce the heat loss of the kiln body.

In addition to the infeed and outfeed owing kiln needs and kilns, and furnaces with a sight glass, test holes, there are no holes, closed tightly, and reduce heat dissipation in the kiln.

Except that feeding and the material needs to establish the kiln gate as a result of the turnover kiln, the kiln side is equipped with outside the port hole, the examination hole, did not have any hole, the seal to be strict, reduced kiln volumetric heat quantity disappearing.
