Roll bearing

Two rigid pillars with removable tops carry the rolls, which are placed either in friction/bush bearings or high quality anti-friction roller bearings. Roller bearings are pretty much standard nowadays, as they allow for 20 – 30 % in power-savings. A lubrication system is no Complete production line mixing mill laboratory rubber mixing machine required.

Roll nip setting

Adjustment of the front roll used to be made by hand (manual by ratchet) or later motorized by worm gear.

Nowadays hydraulic pistons adjust the rolls and also protect rolls from high forces that can build up in between the rolls (roll safety). They also open roll gap immediately when pushing the safety bar in front or back in case of emergency (required by European Safety standards CE).

Rolls

A mixing mill has 2 horizontal rolls set up back to back. They are made of ground chilled cast iron, with surface hardness ranging from 475 – 520 HV (Vickers hardness) up to 520 – 580 HV (or 68 - 72 HSD)
