Description
The roller mill ROI60.60 has been designed and built to meet the needs of some major companies for rock and silica sand grinding.
Is particulary used to grind sand of 2-3 mm in order to reduce the particle size of the product and take it to a size less than 1000 or 600 or 300 microns maintaining a low production of filler.
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 with a dimension table off Ø 600x600, derived from a fusion of special metal alloy Ni-Cr-Mo; dynamically balanced.
On the table can be placed rollers with wear-resistant coating hardness 1350HV Vickers outside.
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.
