In order to adapt to the current severe development situation of the ceramic industry, energy conservation and emission reduction, as well as maximizing unit output to reduce costs, have been put on the development agenda by most ceramic enterprises. Wide body kilns will become the first choice for ceramic enterprises to expand. In response to the development trend of wide body kilns in the future, an investment of 20 million yuan will be made to expand a large-scale shuttle kiln with an annual production capacity of 360000 ceramic roller rods and a roller rod length of up to 5000 mm.
