Sarma V. Pisupati, Vijayaragavan Krishnamoorthy, in Integrated Gasification Combined Cycle (IGCC) Technologies, 2017 2.3.3 Grindability. The grindability of coal is important for entrained-flow gasifiers, which require pulverized coal for dry feeding systems or coal with a wide range of particle size distribution for slurry feeding systems. Because grinding is an inefficient process, …
Grindability is normally measured by determining the number of revolutions in a pulverizer that are required to achieve a given size reduction. This is an indirect measure of the amount of work required for that size reduction. Grindability increases slowly to a maximum at ∼90% carbon and decreases rapidly beyond this point.
1. level 1. Op · 10 mo. ago. For context, this is the first KitchenAid we have owned. Unit is straight out of the box and appears to be making a grinding/clicking noise at low speed which doesn't sound normal. FYI the attachment is not contacting the bowl and the sound appears to originate from the motor itself.
The overall objective of the El Brocal engineers was to determine a way of increasing plant productivity without adding new grinding capacity. With the hydrocyclones closing the Ball Mill circuit these engineers noted circulating loads in excess of 400% and excess slimes production resulting in recovery losses during the floatation process.

Actually, you need to differentiate between capacity and grinding efficiency. At a lower load capacity will be reduced but grinding efficiency will increase. There are only a few examples of this (most sites go for throughput rather than efficiency) but it has been shown to hold true for overflow mills. Sandeep Bisht 6 years ago Like
Low porosity and closed pores will lead to poor chip storage capacity, self-sharpening ability and heat dissipation capacity, resulting in surface blockage, surface burn and destruction of grinding surface integrity . Moreover, grinding wheel with surface blockage needs to be dressed to regain self-sharpening.
