In addition to the above-mentioned slate production line being successfully ignited and put into operation in October, the reporter also learned that many companies are currently planning and building new slate production lines. It is foreseeable that the popularity of rock slab ignition and production will only increase.
In 2017, Guangdong Xinmingzhu Ceramics Group’s investment project to build six slate production lines was approved, with a planned investment of 250 million yuan. With the successful ignition of Xinmingzhu’s 3mm ultra-thin slate production line on August 28 this year, the company now has 4 large-sizedRock slab production line; according to the plan, two more rock slab production lines will be added in the future.

At the 2020 China Rock Slab Summit held on October 20, Dr. Yin Hong, a well-known industry expert, reiterated the topic of "whether rock slabs can bring the ceramic industry back to tens of billions of subversion." He pointed out that at the beginning of the year, some people predicted that the number of slate production lines would reach 300 in the next 3-5 years, and the annual production capacity of slates was estimated to reach 900 million square meters. However, the current production of ceramic tiles has dropped by 1.8 billion square meters from the tens of billions in the disruptive period. To fill this gap, 600 slate production lines are needed, which is almost impossible to achieve.
Regarding the prediction that domestic slate production lines will exceed 100 by the end of 2020, Dr. Yin Hong believes that judging from the current production process of enterprises, there is no need to wait until the end of the year. It is already just around the corner.

Behind the surge in rock slab production lines, rock slab companies have put forward higher quantity and higher quality demands for upstream equipment, raw materials and technology. Yang Xuexian, general manager of Keda Manufacturing Co., Ltd., once said frankly that orders for rock plate presses from Henlitai and Keda are already full, and customers are still chasing them so hard that they dare not even take orders now. It can be seen that the emergence of rock slabs has brought huge business opportunities to upstream equipment manufacturers.
Domestic rock slabsDevelopment began with the introduction of imported slate production equipment, and the most popular imported equipment comes from the two companies Sacmis System. In this regard, Zhang Boqing, a professor at Jingdezhen Ceramics University, believes that foreign rock slab equipment started early and has certain advantages. Although domestic rock slab equipment started late, it is making rapid progress. Facts have also verified this view. The top equipment of domestic slate production lines is no longer exclusively imported equipment.
What is the most advanced slate production equipment at present?
Sacmi
Zhongpeng Thermal Energy
Delitai
Modena
Italy Sacmi Continua+:
This continuous molding equipment can be said to be the most sought-after ceramic machine this year. Companies such as Shuncheng, Xiangda, Xinjincheng, Qianghui, Yinuo, Jiangjun, etc. have invested heavily in purchasing it. Its biggest feature is that it integrates fabric, press forming, blank cutting and other devices, making the thickness and size flexible. Because it is cut on the green body, it generates only 3% waste and can even be 100% recycled.
Italian System large-tonnage press:
Belt forming is a characteristic of System presses, which produce extremely high pressing forces (not less than 40MPa). With its unique fabric and pressing method, System has many excellent properties such as ensuring small density and thickness deviations of the stone slab embryo, high forming accuracy, good density uniformity, and high green strength. As early as 2018, Gold Medal Asia and Nobel were the first to introduce System presses.
Henglitai YP16890 automatic hydraulic press:
Henlitai YP16890 automatic hydraulic press has a pressing force of 168000kN and is suitable for pressing oversized rock slabs with a thickness range of 3-30mm.. The pressing technology of this equipment has the characteristics of obvious energy saving effect, saving powder and ensuring stable quality in the production process. It can also realize real-time displacement monitoring and help enterprises achieve intelligent management. At present, companies such as Mona Lisa, Xinjincheng, and Shengshi Oriental have adopted this equipment.
Delitai Industrial 4.0+ digital intelligent kiln:
When Delitai designed the Industry 4.0+ digital intelligent high-end kiln, it took into account the later deep processing needs of the slate and adopted Keda's unique leading technologies - "three-band" proportion optimization, ARFC proportional combustion control system, The third generation ERSIII tail cooling waste heat recovery and utilization system, TUKS kiln temperature field uniformity system, ICS intelligent control system, HPTS high-precision transmission system, etc., thereby eliminating stress within the rock slab and reducing processing damage.
Modena MDS double-layer kiln, multi-layer drying kiln:
CNC control and precision are the hallmarks of the Modena range of kilns. Its double-layer kiln adopts fully digital management, fully intelligent automatic feedback combustion port heating energy-saving system, high-precision actuator and linear valve to control the gas volume, allowing the dual channels to operate completely independently while controlling the temperature more accurately; while the multi-layer drying kiln Compared with traditional dryers, the roller rotation speed is stable and slow, and there is no vibration. The mechanical damage to the bricks is reduced to a minimum, and it has obvious advantages in drying large-sized rock slabs. In 2020, a total of 7 slate production lines chose Modena's double-layer kiln and multi-layer drying, including slate production lines from companies such as Jiangjun, Xinghui, and Shenghua.
Zhongpeng Thermal Energy’s digital intelligent “high-speed rail era” roller kiln:
The Zhongpeng Thermal High-Speed Railway Era Roller Kiln (KOHSTA) has high-precision transmission, kiln waste heat comprehensive utilization system, kiln data management system, "large screen display system", roller detection and coding machine, roller coating machine, etc. Advanced technology; at the same time, Zhongpeng Thermal Energy also came up with a solution to the common stress relief problem of rock slabs, and achieved uniform cooling by optimizing the firing system. New Pearl, Lingbiao Technology, Nengqiang Qianghui and other companies have introduced this equipment.
In addition to presses and kilns, new equipment and new technologies have been born in every production link of rock slabs. For example, in terms of glaze line, Xinmingzhu adopts industry-leading production equipment such as Italian AIRPOWER and TekMaK automatic glaze spraying cabinets, as well as System 4+12+6 multi-channel inkjet printers, dry granulators, etc. It is currently the best product of its kind in China. and the glaze line with the shortest process; in terms of polishing and edge grinding, the Gold Medal Asia No. 2 rock slab production line uses Nader’s NAPG1400-2800 intelligent rock slab polishing equipment to control the grinding feed amount, large and small heads, and diagonal error control. In terms of packaging and brick storage, Shengshi Oriental has introduced a complete set of Keda's fully compatible automatic packaging line for rock slabs and a full-line brick storage system after the kiln. .
……
The improvement of production equipment and technology has strongly promoted the maturity and scale of the slate industry. At the same time, it has also made the threshold for entry into the industry lower and lower. The pros and cons cannot be discussed in detail.
As the current construction and ceramics industry and even the entire home furnishing industry are still very optimistic about the development of slates, in addition to construction and ceramics companies investing in slate production lines one after another, many stone companies have also entered the field of slates. As Dr. Yin Hong said, 600 slate production lines are difficult to achieve, but 100 are close at hand.
The autumn air is crisp and clear. I believe that the fire of rock slabs will burn stronger and longer.
