Currently, with the promulgation of the national dual control strategies of "carbon peaking" and "carbon neutrality", energy conservation and emission reduction have once again attracted the attention of ceramic enterprises.
On the other hand, since the resumption of production this year, various raw materials have been rising in turn, which has already made ceramic companies unable to bear the excessive cost pressure. In particular, the recent rise in coal and natural gas prices has also continued to boost the prices of various ceramic companies. Enterprise production costs have risen sharply.
Under this situation, how to reduce the production cost of ceramic tiles while taking into account "carbon peaking" and "carbon neutrality" has already become the focus of many ceramic companies.
In fact, as early as the "Twelfth Five-Year Plan" period, relevant departments in my country proposed the research and development work on the topic of "Key Technologies and Demonstration of New Dry Short Process Process for Ceramic Tiles", aiming to reduce production costs, save energy and reduce emissions for ceramic enterprises. problem.
As for Zibo Le Taoshi Energy Saving Technology Co., Ltd. (hereinafter referred to as Le Taoshi Energy Saving Technology), which started early in the research and development of dry powder milling in my country's building ceramics industry and has matured production equipment research and development and process applications, it is closely related to China The dry powdering process and process jointly developed by Xianyang Ceramics Research and Design Institute of Building Materials are now even more like "heroes have a place to play".
Energy Saving and Emission Reduction
Each ton of powder can save 150-160 yuan
It is understood that compared with wet milling, the powder prepared by using the dry powder milling equipment and technology developed by Letos Energy Saving Technology has two major advantages that wet milling cannot match: First, it reduces the cost for ceramic enterprises Massive production costs, secondly, significant energy saving and emission reduction effects.
Taking the northern region as an example, dry powder milling is used to prepare powder. Under the current coal price, each ton of powder prepared saves at least 150-160 yuan for ceramic enterprises and saves more than 80% of energy. The raw material workshop Reduce emissions by more than 90%.
"There are no nitrogen oxides and only a small amount of sulfur dioxide is emitted during the production process of dry powdering. In addition, wet powdering requires 45 cubic meters of natural gas, while dry powdering only requires 5 cubic meters." Chairman of Le Toshi Energy Saving Technology Li Fengzhi said.
In fact, the dry powdering process and process originally jointly developed by China Building Materials Xianyang Ceramics Research and Design Institute and Zibo New Space Ceramics Co., Ltd. (the predecessor of Zibo Le Taoshi Energy Saving Technology Co., Ltd.) have long beenIt has been highly recognized by the industry.
In August 2017, Letos Energy Saving Technology undertook the construction of 1,000 tons per day dry powder milling equipment for Shuozhou Hualun Ceramics Co., Ltd. in Shanxi Province, and successfully applied it to the company's production of various specifications of interior wall tiles; in the same year In November, we completed the construction of dry powder milling equipment with a daily output of 1,600 tons for Hebei Jinhui Ceramics Co., Ltd., and successfully applied it to the production of glazed tiles.
In October 2019, Letos Energy Saving Technology completed the construction of 200 tons of dry powder milling equipment per day for Shandong Binzhou Shunxin Ceramics Co., Ltd., which was used in the production of interior wall tiles.
According to "Ceramic Information", despite the continuous changes in the building ceramics industry in recent years, Letooshi Energy Saving Technology has not given up on promoting the dry powder milling project. At the same time, ceramic companies continue to take the initiative to contact us for cooperation.
Due to rising coal prices, the cost advantage of dry powder milling has become more prominent. Recently, Lion King Ceramics and Letos Energy Saving Technology signed an agreement to cooperate in the production of antique brick powder.
Currently, the dry process production line built by Letooshi Energy Saving Technology for Shuozhou Warren Ceramics has completed the test of producing medium plates, and the production line transformation will be implemented in the near future.
Obvious advantages

In fact, the dry powdering equipment and process jointly developed by China Building Materials Xianyang Ceramics Research and Design Institute and Zibo Le Taoshi Energy Saving Technology Co., Ltd. are welcomed by many ceramic companies mainly because of the ceramics prepared using this equipment and process. Powder can not only reduce production costs for ceramic companies, but more importantly, it can greatly reduce emissions and save energy, thereby achieving the dual effects of energy conservation and emission reduction, which is very consistent with the "dual control" strategy proposed by the country.
It is understood that Letoshi Energy Saving Technology dry milling project has a long history. As early as 2010, the New Space Ceramics project was established with the original intention of reducing production costs, which kicked off the technological transformation of the traditional wet raw material preparation process for building ceramics into a dry preparation process. At that time, it also attracted the attention of the industry. Eyesight, this is also the prototype of dry flour milling that started very early in the entire industry.
1. In 2010, Zibo New Space Ceramics introduced the first vertical mill in the building ceramics industry from Qingdao Luqi Mining Equipment Co., Ltd., thus kicking off the research and development of dry powder milling.
2.In December 2012, by XinThe technical transformation project of changing the traditional wet raw material preparation process of space ceramics to dry preparation process was officially listed as Zibo Enterprise Technology Transformation Project by Zibo Economic and Information Commission; in December of the same year, the project was listed as Shandong Province Enterprise Technology Transformation Project.
3.In January 2013, the “Green Production Technology and Application Demonstration of Typical Building Materials Products Green Production Process” was jointly undertaken by China Building Materials Xianyang Ceramics Research and Design Institute and Zibo New Space Ceramics. "Officially settled in Zibo New Space Ceramics.
4.At the end of 2015, dry powder milling was successfully mass-produced in New Space Ceramics and passed the appraisal and acceptance by the industry organization department.
5.In 2016, we cooperated with Xianyang Ceramic Design Research Institute, and the two parties signed a technology promotion cooperation contract.
6.In 2017, on the basis of extremely stable production, the powdering links of the two production lines of New Space Ceramics were all switched to dry powdering production.
At present, in addition to many cooperative units, many ceramic companies from inside and outside the province have taken the initiative to visit and learn more about the technology, and they have a strong intention to transform the dry powder milling technology.
“At present, coal prices have reached record highs, making ceramic enterprises overwhelmed. Reducing production costs and carbon emissions for ceramic enterprises is the biggest advantage and original research and development intention of our company’s dry powder milling equipment and technology. No matter in the past, present or future, dry milling has huge advantages that wet milling cannot match. From the future perspective, it is also very consistent with national policies and industrial development needs," Li Fengzhi said frankly.
It is understood that "Key Technologies and Demonstration of New Dry Short Process Process for Ceramic Tiles" is a subject of the national "Twelfth Five-Year Plan" science and technology support plan. The device and method for preparing ceramic brick pressed powder jointly developed by China Building Materials Xianyang Ceramics Research and Design Institute and Letoushi Energy Saving Technology have obtained patent protection from the National Intellectual Property Bureau in 2017 (Patent No.: ZL201410004895.6) .
