  • The working principle of ball mill Meetyou Carbide

    522 According to experience, the critical loading amount is about 40% to 50% of the volume of the grinding cylinder. The ratio of the volume of the ball to the volume of the drum is called the filling factor. If the filling factor is less than 30%, the sphere is liable to be in a sliding state, and the grinding efficiency is low.Ball Mill Explained saVRee,Ball mills are usually designed with a maximum reduction factor/ratio of 60:1 although it is possible to achieve reduction ratios of up to 70:1. The electric drive for a ball mill should be able to handle loads where the ball mill is charged by up to 45% with balls. Additional Resources https://911metallurgist/blog/ballmills3 Types of Grinding Media for Ball Mills FTM Machinery,124 It’s a kind of optimal allocation principle, but the specific will be determined according to the material, the grinding media and the ball mill. In order to make full use of the effective volume of the ball mill, materials, water and grinding media should occupy about 80% of the effective volume of the ball mill. Latest blog
