Jiri George Drobny, in Handbook of Thermoplastic Elastomers (Second Edition), 2014. 4.2.3.1.1 Roll Mills. The roll mill is the simplest batch mixing equipment. The principal design consists of two horizontal rolls, usually of equal size, arranged side by side and rotating toward each other at different speeds.
To minimize the roll diameter a four-high or cluster mill is used. A small roll diameter is advantageous because less roll is in contact with the material, which results in a lower force and power requirement. The problem with a small roll is a reduction of stiffness, which is overcome using backup rolls. These backup rolls are larger and ...

High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size.
Three roll mill is a machine designed especially to solve this problem, i.e., to deglomerate and disperse the particles into viscous materials. 6. We tested the three roll mill and found some leaking from the side, what caused the leaking and how to prevent the leaking? Our three roll mill …

High pressure grinding rolls. A high pressure grinding roll, often referred to as HPGRs or roller press, consists out of two rollers with the same dimensions, which are rotating against each other with the same circumferential speed. The special feeding of bulk material through a hopper leads to a material bed between the two rollers.
