The results are summarized in table 16 which shows that in both capacity and
In a second approach comminution efficiency is based on comparing the energy to produce some size distribution parameter of the product from ball milling with that by single-particle breakage. For both materials dry ball milling efficiency was found to be in the range of 25%.
The units of "ball mill grinding efficiency" will be covered in detail in the first part of the module. Alternatively we can say that: Specific grinding rate = Ball mill x Ore grindability of coarse particles grinding in the lab mill in the plant ball mill efficiency
Several factors affect the efficiency of a ball mill for cement grinding. In this article we shall be looking at some of these factors that have been proven to influence grinding efficiency: Mill Geometry And Speed. According to Bond 1954 the grinding efficiency of a mill depends on the ball mill diameter size of the media and mill speed.

Mill Speed . No matter how large or small a mill ball mill ceramic lined mill pebble mill jar mill or laboratory jar rolling mill its rotational speed is important to proper and efficient mill operation. Too low a speed and little energy is imparted on the product.
Stirred Mills have been proven to provide energy savings compared with traditional ball mills. The finer the product required the more efficient stirred mills will be than a ball mill. The attrition grinding action vertical arrangement and the finer media size distribution contribute to make stirred mills more energy efficient grinding machines.
Dry Milling — Tips: 1. Minimize moisture content of feed material; high moisture content over 2% can cause material to cake inside the milling chamber. 2. Continously add grinding aids or additives whether in powder or liquid form while size reduction is taking place. Most dry milling processes require such materials. Their function is to
