Compared with other ball mills that used for the same period, his ball mill grinding efficiency is higher by about 25%. At present, the capacity of the gold ball mill is 180TPH, the particle size of the feed is controlled at about 20mm, and the output easily reaches 200 mesh. Gold ore working site
Variable spacing between the flutes reduces vibration, allowing these end mills to provide fast cuts, smooth finishes, and long tool life. Made of solid carbide, they are harder, stronger, and more wear resistant than high-speed steel and cobalt steel for the longest life and best finish on hard material.
Ball Mills are slow speed horizontal mills with a rugged design and ease of maintenance coupled with excellent performance. Available in sizes up to 15ft / 4.6m diameter and 24ft / 7.3m length. Raymond® ball mills are characterized by their excellent wear life, high availability and easy maintenance. Typical material processed: Petcoke; Bituminous
The ball mill diagram shows the main parts of a ball mill, including the feeding device, the cylinder, the discharge device, the hollow trunnion, the transmission device, the gear cover, the girth gear, the pinion, and the motor. The ball mill can be operated in a wet or dry way, depending on the material properties and the intended use.
Ball mills grind various ores and other materials either wet or dry. There are two kinds of ball mills, grate type and overflow type, due to different ways of discharging material. There are many types of grinding media suitable for use in a ball mill, including Hardened steel, stainless steel, ceramic, flint pebbles.
The advantage of the grid type ball mill is that the ore discharge speed is fast, it can reduce the over-crushing of ore, and at the same time it can increase the output per unit volume. 1. Large row of ore mouth design, stronger processing capacity for lithium ore, up to 160t/h; 2. Equipped with an automatic control system PLC, reducing labor costs, …
