Application of Open Mill
Used to mix Rubber, Silicone, Abrasives, and PVC compounds. Especially in rubber-processing, mills are built for different mixing processes.
Features of Open Mill
1. Roller: Made of chilled casting alloy and uniform thickness with good cooling effect.
2. Frame and cover: Made of steel casting or welded by steel plate, which have safety strength and high precision machinery.
3. Roller gap adjustment device: Options: manual or electric adjustment and gap display.
4. Reducer: fully-closed, hardened gear, forced lubrication, high safety factor, and less noise.
Main Composition of Open Mill
Build Up of Two Roll Mill
A mill is typically assembled on a steel foundation plate, which is again set on rubber-pads or sound-metals adjustable, to isolate noise-levels to the building also to avoid tensions on the mill structure, precisely levelling out of the mill is very important for smooth operation.
Roller 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.
Roller 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).
Rollers
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 HRC).
