In September, two rock slab production lines built by KEDA for E’meishan Jintao Ceramics and Shengshi Dongfang were successively put into production, accelerating the product upgrade and brand promotion for enterprises in the western production areas.
1st line for Jintao with press KD8508 and 2.5m width kiln
Milestone for Jintao's development in the field of slab:
● In 2012, Jintao started the research and development of thin slab;
● In 2017, Jintao planed for the large-scale rock slab；
● In 2018, KEDA built the first rock slab production line above 2.4 meters for Jintao in southwestern China;
● In 2019, Jintao became the first enterprise in China to produce 800x2600x15(mm) kitchen countertops.
On Sept. 19, the new high-end smart rock slab production line built by KEDA for Jintao was put into production successfully, which further diversified production line, improved productivity, reduced application costs and strengthen market competitiveness for Jintao.
This production line mainly produced rock slab with special specifications (700x1300(mm), 800x1400(mm), 800x1600(mm), 900x1800(mm)). The maximum specification is 1000x2000(mm), and the maximum daily output reaches 8500㎡(800x1600x9mm).
In recent two years, small rock slab became popular in the market. Owe to the features of fast pressing speed (up to 9 times/min for 800x1600mm rock slab), stability and reliability, uniform pressing force and small thickness errors, KD8508 has become one of the first choices for enterprises to product small rock slab less than 1000x2000(mm), and it is also one of the main best-selling model of KEDA this year.
In 2018, the rock slab kiln built by KEDA for Jintao achieved two firsts in the industry——the first super-wide rock slab kiln with an inner width of 3.2m and the first kiln adopted transversal-firing mode.
On the new production line, transversal-firing mode is also used in the smart super-wide rock slab kiln, and which makes special designs for advoiding cutting crack, high-precision drive system, upgraded energy-saving system and smart control system.
According to product customization and application system, Jintao has developed different specifications of rock slab, including 600x1200(mm), 700x1300(mm), 800x1400(mm), 800x1600(mm), 800x2000(mm), 800x2600(mm), 900x1800(mm), 1200x2400(mm), 1200x2600(mm), and the thickness is from 6mm to 9mm, 10mm, 15mm, 18mm and 20mm.
At present, the third production line for 3mm rock slab is under construction by KEDA, which will be put into production in end of this year.
2nd line for Shengshi Dongfang with the latest 4.0+ digital kiln
On the 1200x2400(mm) high-end smart production line of Shengshi Dongfang, latest 4.0+ digital rock slab kiln, 7-layer energy-saving (full recycled heat) dryer, full-line tile storage system after kiln, NC polishing production line for ceramic rock slab, compatible auto packing line for slab are all designed and provided by KEDA.
In the factory of Shengshi Dongfang, the finished rock slabs are processed by water jet on site, achieving a perfect 45-degree cutting without any chipping or defective round hole.
To avoid cutting crack and small chip while processing special hole or irregular parts, KEDA take them into consideration during the kiln design period. The kiln adopts KEDA’s unique leading technology: “3-zone” proportional optimization, ARFC proportional combustion control system, the third generation of ERSIII final cooling heat recycling system, TUKS inner-kiln temperature field uniform system, ICS smart control system, HPTS high-precision drive system, etc.
In addition, considering that rock slab has high degree of customizing, its thickness ranges from 6mm-20mm, no matter thick or thin, large or small, the rock slab kiln has the features of well adaptability and high output. The output of kiln for Shengshi Dongfang is 12300㎡ per day.
KEDA also provided the first complete plant tile storage system in the southwest China, which storage capacity is 150000㎡. It plays a role of dispatching between kiln and polishing line which can freely classify and flexibly deploy the product according to different colors on different rails.
