<p>A roll mill 100 features a pair of rollers 2,4 mounted closely adjacent one another, with a preset gap between them, a first pair of bearings 6,14 (614) and second pair of bearings 18,18 (20,20) mounted in two fixed frames 10,12, supporting shafts 8,16 (8,16) of the rolls 2,4. A pair of spacers 30,30 are between the second pair of bearings 18,18 (20,20). The spacers 30,30, which may be interchangeable for other shapes and/or sizes, may provide accurate and tight control of the gap between the rollers 2,4, as also may the frame members 10,12. The rollers 2,4 may be separately driven. The roll mill 100 may be used for the disintegration of rubber crumb from tyres.</p> |
