Fote roll crusher is widely used for medium and fine crushing of medium hardness of minerals and rocks in the sand making, ore dressing, cement, metallurgical, chemical and building materials industries
1. Fote roll crusher is mainly composed of roller bearing, roller support bearing, compacting and adjusting device, driving unit and other components.
2. Adjustment of discharging granularity: there is a wedge or shim adjusting device between two rollers, when the adjusting bolt pulls the wedge up, the wedge rolls the moving roller away, that is, the gap between two rollers will get bigger and the feed size gets bigger; when the wedge is down, the gap between the two rollers will get small under the impact of pressure spring, the feeding size gets small.
3. The drive mechanism of this roll crusher consists of two electric motors, which rotates according to comparative direction by means of chains or V-belt transmission onto the grooved wheel dragging rollers. When crushing he materials, Materials from the inlet through the roller, will be crushed through rolling and the crushed materials will be discharged from the under frame.
4. For safety, the chain or belt of the driving part will be installed safety shields according to actual conditions. We should pay special attention to the following matters in the work of roll crusher. We should strength the work of iron ore removing. The non-crushing (drill bit) can damage the roll crusher once they have felt into the rollers, thus resulting in stopping accidents. So, we should install iron removal device before the using of crushers.
