rubber rolling mixing mill with manual gap adjustment device/XK450 rubber mixing mill machine
Brief introduction of Rubber mixing
Machine Overview:
Two roll Mixing Mills are designed to ensure perfect and uniform blending of natural and synthetic rubber with other raw materials. These mills provide uniform mixing of the material to the desired level. Most of the mixing mills are driven by electronic motor and different models have different output
Main features:
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 longer 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). The depth of hardened layer ranges from 10 to 16 mm.
