In 2021, the thick tile production increased rapidly in Fujian China, at present, there are about 100 thick tile production lines in Fujian. The rise of the thick tile production provides new growth space for Fujian exterior wall tile manufacturers, but it also brings mixed quality and vicious price competition, many production lines have been transformed from the exterior wall tile production lines, for which, the quality and energy consumption cannot be guaranteed.
Recently, two wide-body kilns constructed by KEDA in Fujian have been successfully put into operation, setting a new benchmark in Fujian production area in terms of kiln output and unit energy consumption.
Fujian Jinjiang Xiangda Ceramics' new production line for thick tile and rustic tile, is designed with output of 10,000 ㎡/day, at present, its output has reached 11,000㎡/day. Its products mainly include 300 × 300(mm), 300 × 600(mm), 600 × 600(mm), 600×900(mm), 600×1200(mm), with thickness from 12-30mm and water absorption rate from 0.15%-0.2%.
Xiangda Ceramics was founded in 1992 and located in Cizao Town, Jinjiang City. As one of the drafter of the industry standard for "thick tiles", Xiangda Ceramics currently has two production lines, mainly engaged in thick tiles and wall curtain panels production, with output over 20,000 ㎡/day.
The new production line of Caiba Ceramics in Quanzhou, Fujian mainly produces thick tiles with thickness 18mm from 300×300(mm) to 600×1200 (mm), the water absorption from 0.2%-0.3%, and the designed output of the kiln is 12,000㎡/day. The current output reaches 13,000 ㎡/day, and the annual output can reach 4.6 million ㎡.
Caiba Ceramics was built in 1995 and located in Cizao Town, Jinjiang City. The production base covers an area of more than 300 mu and has an annual production capacity over 10 million square meters. Its full body tile kiln output for exterior wall tile and rustic tile have been widely praised by the customer for their excellent product quality, and have become one of the iconic brands in Fujian production area. Its products are exported to Europe, America and the Middle East.
For the problems of difficult drying, oxidation, slow cooling, heavy load and slow transmission of thick tiles in firing, KEDA has adopted a number of innovative measures such as multi-layer drying, oxidation in advance, and enhanced transmission to ensure product quality; at the same time, gas consumption is lowered through fully combustion, and the combustion-supporting air heating technology, the automatic temperature control technology, and the recycling heat utilization. The overall energy consumption of Xiangda and Caiba are as low as 2.3 Nm³/㎡ of natural gas.
In Fujian production area, there are 10 thick tile production lines provided by KEDA, leading thick tile kilns development towards wide body, large output and low energy consumption, which has promoted the upgrading of products and production lines, and endowed the product with stronger vitality.
