Oct 05, 2016 · The comminution efficiency of a HPGR is better than ball mills such that it consumes 30–50 % of the specific energy as compared to a ball mill. Four circuit configurations of HPGR can be used in grinding of raw materials, clinker and slag such as : Pre-grinding unit upstream of a ball mill. Hybrid grinding. Semifinish grinding

what factors will influence ball mill grinding efficiency?

what factors will influence ball mill grinding efficiency?

Mar 26, 2021 · Ball mill grinding efficiency is influenced by many factors: ore grindability, feed size, grinding product size, ball mill diameter and length, ball mill working speed, liner type, steel ball loading system, grinding concentration, return sand ratio in closed-circuit grinding and feed rate. (Ball mill) To improve the ball mill grinding efficiency, you must first understand the factors that

addition of pebbles to a ball-mill to improve grinding

addition of pebbles to a ball-mill to improve grinding

The grinding capacity, when using a mixture containing 25% pebbles, was the same as that with balls alone, resulting in a 13% saving in energy and an implied saving in ball consumption of 25%. It was concluded that the use of a composite load for secondary grinding is a very attractive option
