In China's ceramic industry, polishing machines and edgers are just equipment, and almost all types of tile production lines are equipped with such polishing equipment. However, according to industry insiders, the domestic ceramic tile edger field has experienced a decline after the peak of production and sales two or three years ago. "At present, the domestic edging machine is very mature in technology and products. The biggest pressure and difficulty faced by related equipment enterprises lies in the market sales. In addition, the production and sales of edging machines are more and more concentrated in the first-line brands." It is believed that several equipment companies such as Keda Jieeng, Yiding Technology, Saindi Technology, Jinbot Machinery, and Basil Electromechanical Co., Ltd. occupy the leading market of the edging machine in the ceramic industry.
With the development of the edging process and the improvement of related supporting materials, the dry grinding process has gradually become the mainstream of the edging and chamfering of the ceramic industry. Energy efficiency and efficiency have become the direction of innovation and improvement of the edger.
After the peak, it is now falling, production and sales and brand are more concentrated
According to Zhang Hongwei, deputy director of marketing of Guangdong Yiding Technology Co., Ltd., the production and sales of the edging machine is closely related to the overall situation of the ceramics industry and the number of new production lines.
According to the data of the National Ceramic Tiles Capacity Survey conducted by the Ceramics Information Press in 2014, the peak of three new production lines in China's ceramics industry in the past decade has been in 2007, 2010 and 2013.
Zhang Hongwei said that with the construction of new large-capacity production lines in Henan, such as Henan Neihuang, Yunnan Yimen, Hebei Gaochun, Guangxi Tengxian and Hezhou, etc., the new large-capacity production lines emerged in 2012-2013, while the old production lines changed production ( For example, if the polished brick production line is changed to ceramic tile, antique brick, full polished glaze, etc., and the equipment is replaced, the demand for the edger is greatly increased in 2012 and 2013, and there is a peak of production and sales.
With the depression of the ceramic industry in the past two years, overcapacity, oversupply, vacant production lines are increasing, and the number of new production lines is decreasing. In addition, the environmental management of the ceramics industry is tightened, and the ceramic enterprises invest in equipment. More consideration will be given to environmental protection, and the replacement of conventional equipment will be relatively reduced. Under the above various factors, the edging machine industry has declined in the past two years.
In the development process of the edging machine in China's ceramic industry in recent years, due to the intensified market competition, the homogenization of products is widespread, and the price of the edging machine has also declined significantly.
“The market price of a 36+4 (grinding wheel, number of grinding heads) edging machine production line in 2007 was 45~480,000 yuan, while the current price of 48+8 products is about 300,000 yuan. This is like a car. The configuration is higher, but the price is lower," Zhang Hongwei said.
“A ceramics company in Shanxi is about to build a large-scale ceramic tile production line. Recently, more than a dozen ceramic equipment suppliers have come to discuss the equipment order with the person in charge of the ceramics company on the same day. Suppliers can only arrange from morning to night. The team took turns to conduct negotiations, and most of the suppliers knew each other. The scene was very lively and almost no less than the bidding meeting.†Ding Jianming, general manager of Foshan Aitao Electromechanical Equipment Co., Ltd. told the reporter quite helplessly. At present, the market competition of ceramic machine equipment is quite fierce. Many ceramic enterprises often choose the first-line brand after many goods.
The Shanxi Tao enterprise is exactly the same. After repeatedly comparing the equipment of each production link, it finally selected several brands and cooperated with better suppliers.
Dry grinding gradually becomes the mainstream and becomes the development trend
At present, the edging process of ceramic tiles mainly adopts two processes of dry edging and wet edging. According to industry professionals, the wet grinding process has been promoted and applied more than ten years ago. Before and after 2007, the dry grinding process was first applied in the edging of ceramic tiles, and then the dry grinding process gradually became the mainstream in the industry.
It is understood that at present, the production of porcelain tiles and antique brick products in China mostly use the dry edging process, while the products with low water absorption rate (such as polished tiles) still use the wet edging process.
Compared with the traditional wet edging equipment, the dry edging production line adopts the innovative grinding head structure and cooling system design, which has the following advantages: saving the investment and land occupation such as drying (drying after wet grinding), water treatment, etc. And energy waste; direct packaging after edging, no need for waterproof plastic film, saving packaging costs; better working environment, grinding residual materials can be recycled after collection. In addition, the dry grinding chamfering of the product with high water absorption by dry grinding can avoid the influence of moisture on the color and color of the product, and better maintain the quality of the tile.
The person in charge of Foshan Jinbote Machinery Co., Ltd. told the reporter that the relative energy consumption of dry grinding is higher than that of wet grinding, but it can save comprehensive production cost. Countries with developed ceramics such as Italy and Spain have already achieved dry grinding of porcelain bricks with extremely low water absorption.
Ding Jianming said that depending on the geographical and market differences, the edging process will be different. In northern China, water shortage, compared with southern Guangdong and other producing areas, the production of ceramic tile products in the northern region is lower in firing temperature and product density, and the water absorption rate is relatively higher, so more dry grinding processes are selected. In foreign countries, there is no process of edging in the production process of some ceramic tiles. First, because the ceramic enterprises in European countries are operating in a standardized process, the quality of products is good; second, relatively backward regions and countries, such as Africa and India. Etc., the tiles produced are very popular, and consumers and manufacturers will not pay attention to the details of the corners.
Many industry insiders agreed that the dry grinding process is the trend of chamfering ceramic tiles. At present, ceramic enterprises mainly choose the edging process according to the water absorption rate and quality of ceramic tile products.
Large-volume edging machines are emerging, and innovation should be tightly wrapped around energy-efficient
At the industrial exhibition in June this year, many ceramic equipment companies unanimously launched a number of energy-saving and efficient edge grinding machines.
Saindi Technology has introduced a high-efficiency wet edger with a 30% improvement in efficiency compared to conventional edgers. It can achieve the same cutting effect of the original 12 groups (96KW) with 7 sets (77KW).
Yiding Technology's completely dry edging production line (high-speed type) can achieve completely water-free, stable, high-efficiency, accurate, large-volume effect, and the diagonal error can be controlled below 0.5mm. It is worth mentioning that in the first half of this year, Yiding Technology successfully launched the edging machine that can be applied to the dry grinding of polished tiles. Zhang Hongwei said that the next tripod technology will further extend the dry edging process to the double-zero standard (that is, the water absorption rate is 0.02%, ≤0.09%), which is the edging process of ceramic tiles. Will have a huge impact.
As an expert in edging machine, Jinbot Machinery mainly promotes the production of “Big Mac†antique brick 19+1 dry edging machine with a daily production capacity of 18,000 square meters.
Zhang Hongwei said that any product has its production and sales cycle, and it is normal to have it. Energy-saving and high efficiency must be the development and innovation direction of ceramic machine equipment products. Enterprises should pay attention to innovation in process technology and products, improve product quality and service level, adapt to market changes, and make enterprises more competitive.
Ding Jianming believes that the innovation and improvement of the edger is nothing more than how to achieve higher efficiency, more energy saving, and greater productivity. In the process of innovation, related grinding wheels, grinding tools, motors, belts and other supporting materials need to be systematically upgraded accordingly. In addition, the concept of industrial design should be introduced more, and the development and progress of the ceramic industry should be promoted through equipment and technology.
