Direct-driven efficient environment-friendly energy-saving center transmission ball mill

A direct-driven efficient environment-friendly energy-saving center drive ball mill relates to the technical field of mining equipment and comprises a feeding mechanism, a rotating body, a discharge hopper and a permanent magnet synchronous motor, and the rotating body is supported by a bearing and comprises a horizontally-arranged charging barrel and a hollow discharge shaft connected with the discharge end of the charging barrel. The hollow discharging shaft penetrates through the discharging hopper and is provided with a discharging hole for discharging the ball-milled materials into the discharging hopper, the feeding end of the charging barrel is connected with the feeding mechanism, the hollow discharging shaft is connected with an output shaft of the permanent magnet synchronous motor through the coupler, and the axes of the charging barrel, the hollow discharging shaft, the coupler and the output shaft of the permanent magnet synchronous motor are aligned. According to the scheme, the ball mill is dir
