The rod mill is driven by motor with speed reducer and peripheral large gear or low speed synchronous motor with peripheral large gear. The grinding medium --- steel rod is put into the cylinder which is lifted and then fall under the action of the centrifugal force and friction force. The materials entering into cylinder form the feeding inlet are grinded by movable grinding medium and discharged out by overflow and continuously feeding.
Cylindrical energy saving grid ball mill consist of feeding part discharging part rotary part transmission part reducer small gear motors electrical control and other major parts. Hollow shaft is steel castings and the liner is detachable. Rotary gear is Processed by casting hobbing. The cylinder is lined wear-resistant liner plate with good resistance to wear. This machine works stably.
The mill with coarse particle product is common used in the first stage grinding.
Xinhai rod mills include overflow rod mill end peripheral discharge rod mill and center peripheral discharge rod mill which could meet different requirement.
