Optimize the grinding process according to the ore properties of the original ore, such as pre-throwing, pre-concentration, stage grinding, and pre-classification, which can reduce the amount of grinding, recover useful minerals in time, and improve the grinding efficiency of the ball mill.
The micro-mechanism of ball grinding is considered to be a loose-bed comminution . Therefore, types of balls have significant effects on the grinding efficiency, namely throughput and energy efficiency. Ball grinding processes encounter inefficient performance since the collisions of grinding balls are random .
The effect of low ball% full on grinding efficiency is: The throughput of mill will decrease with the time; The P80 in the discharge of the Mill, will increase because of the high time of particle residence in the Mill, and for this reason the grinding will be lower efficient. The power specific consumption will increase, due to the lower feed ...
They dominate these grinding applications because greater stress intensity can be delivered in stirred mills and they can achieve better energy efficiency than ball mills in fine and ultra-fine ...
Ball mill is an efficient tool for grinding medium hardness ore and other materials and widely-used in many industries such mineral preparation, metallurgy, chemical industry, building material, thermal power industry, and etc. There are two grinding ways of the ball mill: The dry process and the wet process.
The use of ball mills for wet grinding of various materials is a very common and efficient process. Ball mills are used to grind raw materials, ores and minerals (like lime or limestone) for flue desulphurization, coal and several other raw materials. Ball mills can be of two types, based on the different ways materials are discharged.
Here are ten ways to improve the grinding efficiency of ball mill. 1. Change the original grindability. The complexity of grindability is determined by ore hardness, toughness, dissociation and ...
