AMIT 135 Lesson 7 Ball Mills amp Circuits – Mining Mill . Mill Type Overview Three types of mill design are common The Overflow Discharge mill is best suited for fine grinding to 75 – 106 microns The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 – 250 microns The CenterPeriphery.
Ball mills have been manufactured for over 150 years, and have become an industry standard for dry minerals grinding. A ball mill is still the preferred solution for many types of dry grinding duty. A ball mill consists of a rotating horizontal cylinder, containing a cascading grinding media, typically steel or ceramic balls, in the range of 10.
Dec 26, 2019 1. Overflow type discharge ore through the hollow shaft. When the ore discharge surface is higher than the slurry surface, the finished product is discharged and the ore is automatically discharged by gravity, thus the overflow ball mill saves energy. 2. Grate discharge ball mill the ore is discharged through the grate plate.

Ball mills are usually either of the grate (diaphragm) or overflow type. Ball Mill Components. Ball mills consist of the following components Inlet – crushed ore is fed to the ball mill through the inlet. A scoop ensures the feed to the mill is constant. Discharge – reduced feed exits the mill through the discharge. Ball Mill Components.
Ball mill is one of the most variable and effective grinding machines which is mainly applied for further grinding the crushed materials. Compared with other grinding mills, the variety of grinding modes, available grinding tool materials, and flexible production capacity make ball mill grinders the perfect match for a vast range of applications, such as cement industry, new building.
