Grate ball mill (grate discharge ball mill) is a ball milling machine used to grind various ores and other materials. Grate type ball mill is a traditional ball milling equipment for forced ore discharge by ore discharge grate.. Its basic structure and grinding process are basically the same as the overflow type ball mill, but the structure of the ore discharge part is different.

MoreThe discharge grate plate of the ball mill directly affects the grinding effect of the ball mill, but the current discharge grate plate is often seriously blocked, which leads to problems such as smaller ventilation area, poor ventilation and over grinding of the ball mill, affecting the normal operation of the ball mill. Therefore, Fodamon engineer optimized and transformed the discharge ...
