The roller mill ROI4F
Roller mill suitable for grinding calcium oxide, also suitable for grinding rock up to 100 mm.
Suitable for obtaining either 3-9 mm, 9-15 mm, 15-20 mm product size, according to the user needs. With a minimum production of fine particles less than 3 mm.
It is a machine of extraordinary strength and stability, appropriately sized to withstand maximum loads with minimal vibration.
The feeding is through a dosing roller with helical grooves which guarantees a uniform distribution of the product on the grinding rolls. The roller speed is adjustable by a hydraulic speed variator.
The grinding is performed by two pairs of rollers made from a special casting metal alloy, dynamically balanced to allow two independent ways.
The steel of the roller shafts are machined with conical seat and thread to the bearing housing.
The disassembly of the bearings is effected with extreme simplicity by means of a hydraulic extraction system.
The adjusting system of the distance and the parallelism of the rollers is micrometical.
A hydraulic control unit adjusts the working pressure.
The two nitrogen tanks are placed within the hydraulic unit, to allow a constant cushioning effect in the event of passage of foreign bodies.
