The grinding process in ball mills and vertical roller mills is fundamentally different [15]. Following are advantages of VRM over Ball Mills with reference to these issues: - • Strong drying ability - Inlet hot air from Kiln can dry materials with 20% water content. (max moisture 20% vs. 3% in ball mill) [15], [16]. •
This new high energy or power rate crushing brings a different perspective to comminution flow sheet selection. Generally, up until the early 1960's the classical flow sheet for a beneficiation plant was primary crushing followed by two stages of cone crushing in closed or open circuit, making feed for rod mills, followed by ball mills.
Cut-away view of the Hardinge conical ball mill showing how energy is proportioned to the work required. ... the ball mill was not as efficient as the other methods for cell disruption [155]. ... the angle of the cone being about 30°. Due to the centrifugal force generated, the balls are segregated so that the largest are at the feed end of ...
The voids (or interstitial space) within a rod load are approximately half those in a ball mill grinding load. Rods in place weigh approximately 400 pounds per cu. ft. and balls in place approximately 300 pounds per cu. ft.. Thus, quantitatively, less material can progress through the voids in the rod mill grinding media than in the ball mill ...
