The conference lasted two days. During the conference, more than 50 industry experts and scholars, representatives of sandstone and equipment enterprises focused on the key points and thoughts of the 2022 national standard revision, the certification and standard interpretation of green factories in the sandstone industry, the resource utilization of solid wastes, the intelligent and green large-scale construction of mines and production lines, the ecological restoration of sandstone mines, and the green and energy-saving production processes and equipment, As well as investment and financing of the sand and gravel industry and related legal risks and prevention.

Kai Naijie, manager of Jiangsu Jiaxuan building materials industry

Kan Nai, manager of building materials industry of Jiangsu Jiaxuan Intelligent Industrial Technology Co., Ltd., is a masterpiece of the theme report entitled "upgrading of industrial drive system to permanent magnet intelligent direct drive". The report points out that under the background of green development of sandstone mines, Jiangsu Jiaxuan Intelligent Industrial Technology Co., Ltd. has actively participated in the national policy of "carbon peak and carbon neutralization", developed permanent magnet direct drive technology to be applied in the sandstone aggregate industry, green drive and intelligent drive, and provided users with a complete set of solutions for the driving system of the sandstone industry, which has been continuously improved and improved year by year. Since 2018, the company's permanent magnet direct drive roller has been applied to the drive system of belt conveyor in the sand and stone industry, which is composed of permanent magnet drive roller and frequency converter. The innovative technology eliminates the reducer, hydraulic coupler and coupling. It adopts permanent magnet motor technology, direct drive technology, external rotor motor technology, and a new type of driving equipment designed by combining with the driving drum, which is suitable for driving various types of belt machines. The system has high reliability; Low maintenance cost; Less space; Less noise; Improve the driving efficiency by more than 10% and save energy by more than 20%.
