All ball mills are sold with motor, gears, steel liners and optional grinding media charge/load. Ball Mills or Rod Mills in a complete range of sizes up to 10′ diameter x 20′ long, offer features of operation and convertibility to meet your exact needs. They may be used for pulverizing and either wet or dry grinding systems.
The grinding media, also referred to as grinding balls or grinding beads, serve as the tools in mills with freely moving grinding media, such as agitator ball mills. The movement of these grinding balls within the mill generates various stresses between the balls and the product, including impact, pressure, friction, and shear.

Cylpebs: Cylpebs are slightly tapered cylindrical grinding media with rounded edges. They are commonly used in cement and mining industries for finer grinding in ball mills and other grinding equipment. Glass Beads: Glass beads are used in grinding and dispersing applications for materials like pigments, dyes, and coatings. …
Milling media is crucial for grinding substances into fine powders or reducing them to a desired particle size. If you're looking for effective solutions for your research and development (R&D) team or any other research application that requires controlled particle compositions, milling media is a valuable investment.
The ball mill grinding media typically consists of spherical or small cylindrical steel cylpebs, although materials such as steel, ceramic, glass, and even rubber can be used. This variety allows the ball mill machine to grind raw materials with different properties and hardness levels.
The performance of grinding media in a ball mill is measured in terms of wear rate, which is a function of the media composition, hardness, phase structure, and corrosive–abrasive characteristics of the slurry. The wear mechanisms involved in a ball mill are impact, abrasion, corrosion, and erosion. ...
Plastic Grinding Media. Plastic ball mills are made from high quality and special resin. Plastic ball mills can be used as a substitute for metallic ball mill in low load bearings and they are cost effective. They can be used in various applications, they can serve as agitators in aerosol spray cans, medical diagnostics, etc.
