Small Scale Ball Mill (0.5–15 TPH)

A small-scale ball mill is a grinding device that uses a horizontal rotating cylinder filled with grinding media to reduce particle size. As the mill rotates, the media and material rise and fall, causing impact and attrition that break down particles.
It is used for intermediate and fine grinding and can operate in both dry and wet conditions.

Operational Principle

• Material and grinding media rotate inside the cylinder
• Media rises with rotation and falls due to gravity
• Particles break due to:
• Ball-to-ball collisions
• Ball-to-liner impacts
• Energy transfer from potential to kinetic energy causes particle breakage

Options

• Rubber liners instead of steel
• Steel mounting frame
• UL motor

• Primary grinding (feed from crushers)
• Secondary grinding (feed from rod mills or similar units)
• Regrinding operations
• Mineral processing
• Intermediate and fine size reduction
