Double Roll Crusher Crushes Materials with Medium Hardness

The double roll crusher are easily replaced by undoing the retaining bolts on either side of the crushing segment and sliding off the centre barrel. The teeth on either roll are timed to mesh perfectly to produce a product of 20 x 20mm which crushing 4mm thick cobalt plate. The gap between the two rollers becomes bigger and then the discharging granularity becomes bigger. When the wedge goes downwards, the gap of the two wedges becomes smaller and then the discharging granularity becomes smaller.Double roll crusher are connected via heavy duty straight cut gears to ensure timing of the toothed segments. A simple grease lubrication point is provided. Adjustment of discharging granularity: There is wedge or gasket adjustment device between two rollers of roller crusher. The adjusting screw bolts are fixed on the head of wedge head. When the adjusting screw bolts pull the wedge upwards, the wedge makes the roller be apart from fixed pulley. Double roll crusher, also named roller crusher, which is commonly used in the cement, chemical industry, electricity, metallurgy, building materials, refractory material and other industries. Double roll crusher mainly crushes materials with medium hardness such as chalk, slag, coke, coal and so on. Than roll crusher, jaw crusher is widely used aggregate crusher to crush all kinds of materials in mining, metallurgy, public road, railway and so on. So we can see that it seems to be a little different between these two crushers.The below details are the basic information about how to take more specific precautions to roll crusher at work, it will help the equipment operators know the skills to maintain the higher quality of roll crusher, and extend the operation time of crushing equipment. It is really such a meaningful thing for the whole mining equipment industry.stone cone crusher: http://www.hx-jawcrusher.com/pp/pcone-crusher.html
