fragmentation data from an online system. The results can show a number of different things, but most importantly it tells the operator either: a) The crusher needs to be gapped on a more regular basis based on the increased fragmentation size b)The crusher is being gapped too often when it is not required, allowing for less downtime.

The fragmentation of the material results from the continuous compression that takes place between the liners around the chamber. An additional crushing effect occurs between the compressed particles, resulting in less wear of the liners. This is called interparticular crushing also.

Effects of Fragmentation on Computer Performance. Many users blame computer performance problems on the operating system or simply think their computer is “old”, when disk fragmentation is most often the real culprit. The weakest link in computer performance is the disk. It is at least 100,000 times slower than RAM and over 2 million times ...

Jan 22, 2014 Recently, a novel biomass pulverization technology was proposed by our group. In this paper, further detailed studies of this technology were carried out. The effects of feed moisture and crusher operational parameters (rotor speed and blades gap) on product particle size distribution and energy consumption were investigated. The results showed that higher rotor speed and smaller blades …
