Advantage

  • 1 Energy-conserving compared to old model, 40% energy consumption will be reduced and cost decreased.

  • 2 High grinding efficiency with uniform particles suitable for milling toxic and highly-abrasive materials since it can be used in a completely enclosed form

  • 3 Even output adopting advanced output controllable technology and combination with clients' actual grinding material

  • 4 strong capacity our company uses proper grinding bar, which changes the traditional point contact into line contact, assuring the output more even, capacity increased almost 50%

    • Brief Introduction

    Videos shot by our engineers in manufacturing plant. Ball mill, Using the double tiered roller axletree, with centripetal spherical surface as the support of the host axletree, can reduce energy cost by 30%.

    Working principle

    Ball mill is horizontal cylindrical rotating device, driving by brim gearwheel; one or two chambers; model; grid mill and overflow mill. For two chamber mill, the material goes into the first chamber through the feeding inlet, inside the first chamber, there are stage liners and ripple liners as well as steel balls with various kinds. The shell rotates which generates eccentricity, this force brings ball to a certain height and then balls drop down by gravity, the impact is the grinding force to the material. After the primary grinding in the first chamber, material goes into the second chamber through segregate screen, in the second chamber, there are flat liners and steel section, after the secondary grinding, material is discharged through the discharging screen.
