The first batch of ultrafine grinding equipment will be born

The first batch of ultrafine grinding equipment will be born Recently, the Ministry of Industry and Information Technology released the “Circular on Printing and Distributing the Second Batch of Industry Standards in 2013”, the “Two Test Methods for Mechanical Impact Ultrafine Grinding Equipment” and the “Fluidized Bed Air Flow Crusher” were included in 2013. Machinery industry standard project schedule. This marks the birth of the first batch of industry standards in China's ultrafine grinding equipment industry.

It is understood that these two standardization and revision work will be conducted under the leadership of the National Standardization Technical Committee for Particle Characterization and Sorting and Screening. Zhejiang Fengli Crushing Equipment Co., Ltd., Quanyou Group Co., Ltd. and Zhongji Productivity Promotion Center are The main drafting unit.

It is reported that at present, there is no unified industry standard and national standard for China's ultrafine crushing equipment industry. Production enterprises organize production according to their respective enterprise standards. To change this situation, improve industry competitiveness and facilitate user equipment selection, Zhejiang Fengli Crushing Equipment Co., Ltd. submitted an approval to the National Standardization Management Committee for the establishment of an ultrafine crushing equipment working group consisting of dozens of industry experts and entrepreneurs from institutions of higher learning, research institutes, manufacturing enterprises, and standards management institutions.
