Roller mill suitable for grinding inert products.
It is a machine of extraordinary strength and stability, appropriately sized to withstand maximum loads with minimal vibration.
The grinding is performed by a pair of rollers made off a casting of a special metal alloy NiCrMo, dynamically balanced.
As an option:The rollers can be coated with tungsten carbide to increase their wear resistance.The hardness of the outer surface of rollers is 1350 Vickers.
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.
