The "Mechanical Impact Ultrafine Grinding Equipment Test Method" (JB/T 12837-2016) approved this time specifies the test conditions and requirements, test preparation, test items and methods for mechanical impact ultrafine grinding equipment; applicable to mechanical impact Ultrafine grinding equipment and systems. Fluidized bed jet mill (JB/T 12838-2016) specifies the product model and basic parameters, requirements, test methods, inspection rules, signs, packaging, transportation and storage of fluidized bed jet mills; The fluidized bed jet mill for ultrafine pulverization of dry materials with a Mohs hardness of 10 or less is also suitable for use in a classifier integrated air jet mill.
It is understood that Zhejiang Fengli Crushing Equipment Co., Ltd., as the first drafting unit of the “Test Method for Mechanical Impact Ultrafine Grinding Equipmentâ€, has long been focusing on standard research and formulation. The company has formulated 287 various types of standards, covering the needs of production, management, management, etc., and has passed the standardized A-level certification in 2005. The company formulates special budgets each year to support the standardization work and actively participates in the revision and revision of national standards and standards. As the second drafting unit involved in the formulation of the "fluidized bed jet mill" standard.
In order to change the situation of China's ultrafine crushing equipment industry, there is no unified industry standard and national standard, to enhance the competitiveness of the industry and user-friendly equipment selection. As the leading enterprise of China's crushing equipment industry, Zhejiang Fengfayuan initiated and established a national particle. The work team of the Supermicro crushing equipment of the Characterization and Sorting and Screen Standardization Technical Committee was approved by the National Standardization Management Committee. The secretariat of the working group is located in Fengli, Zhejiang Province and is responsible for the preparation and revision of national standards in the field of ultrafine grinding equipment. At the beginning of September 2009, the first working meeting for the formulation of standards for ultrafine grinding equipment in China was held in Hangzhou. A number of standards urgently needed by the industry were drafted, and the first lead drafting unit was implemented.
In June 2013, the "Mechanical Impact Ultrafine Grinding Equipment Test Method" and "Fluidized Bed Air Flow Crusher" were included in the Ministry of Industry and Information Technology's 2013 Machinery Industry Standard Project Plan. Under the guidance of the National Particle Characterization and Sorting and Screen Standardization Technical Committee, the standard drafting unit gathered the giants of China's crushing equipment industry, Zhejiang Fengli Crushing Equipment Co., Ltd., Kunshan Chuyou Equipment Manufacturing Co., Ltd., and the China Machine Productivity Promotion Center. Chinese metrology institutes and other professional units and industry colleagues participated in the project. After repeated submission of opinions, several drafts were eventually formed.
Zhejiang Fengli has been actively engaged in the work of the 5th member of the National Particle Characterization and Sorting and Screening Standardization Technical Committee since it was the secretary general of the ultrafine crushing equipment. It has achieved remarkable results and won the title of “Zhejiang Standard Innovative Enterpriseâ€.
Ultramicro crushing equipment industry ended without JB standard history
Recently, the Ministry of Industry and Information Technology of the People's Republic of China announced the approval of 587 industrial standards in Announcement No. 17 of 2016, in which the "Standard Test Method for Mechanical Impact Ultrafine Crushing Equipment" and "Fluidized Bed Air Flow Crusher" ranked second and third consecutively. , which announced the end of China's ultra-micro-pulverization equipment industry without JB standard history.
