Offering two times the life of a standard carbide end mill, the end mills in these sets have two milling ends so you can switch to the opposite end when one end wears out. Made of solid carbide, they're harder, stronger, and more wear resistant than high-speed steel for the longest life and best finish on hard material.
- Diameter and Length: Ball mills are typically available in diameters ranging from 0.6 meters to 4 meters and lengths ranging from 1.5 meters to 12 meters. The size of the mill is directly proportional to its capacity and the size of the particles it can produce.

The ball impact energy on grain is proportional to the ball diameter to the third power: 3 E K 1 d b. (3) The coefficient of proportionality K 1 directly depends on the mill diameter, ball mill loading, milling rate and the type of grinding (wet/dry). None of the characteristics of the material being ground have any influence on K 1.
For handling strenuous wet or dry grinding, our ball mills handle continuous millings through the use of chrome steel balls or ceramic balls as grinding media for varied …
Principle of Ball Mill: The size reduction in the ball mill is a result of fragmentation mechanisms (impact and attrition) as the balls drop from near the top of the shell. Mixing of feed is achieved by the high energy …
