Angle Of Nip In Toothed Roll Crusher Reducing Roll CrusherSizer Downtime with WeldOn Teeth At another mine in Utah a McLanahan HeavyDuty Double Roll Crusher was processing phosphate ore using hardened steel segments with each tooth hardsurfaced Due to the speed at which the roll assemblies were turning combined with a high feed rate and large feed size the customer was forced The particles are drawn into the gap between the rolls by their rotating motion and a friction angle formed between the rolls and the particle, called the nip angle The two rolls force the particle between their rotating surface into the ever smaller gap area, and it fractures from the compressive forces presented by the rotating rollsDual roll crushers, how they functionTable 61 gives example values for 1,000 mm roll diameter where the angle of nip should be less than 20° in order for the particles to be gripped (in most practical cases the angle of nip should not exceed about 25°) Table 61 Maximum Diameter of Rock Gripped in Crushing Rolls Relative to Roll DiameterRoll Crusher an overview ScienceDirect Topics

Dual roll crushers, how they function
Roll crushers have a theoretical MAXIMUM reduction ratio of 4:1 If a 2 inch particle is fed to the roll crusher the absolute smallest size one could expect from the crusher is 1/2 inch Roll crushers will only crush material down to a minimum particle size of about 10 Mesh (2 mm) A roll crusher crushes using compression, with two rolls 1 = Nip roll velocity E = Elasticity of the material A = Cross sectional area of the material The larger the elasticity (E), the less likely the material is to stretch For most values of EA, use TORQUE CONTROL For stretchy material, where E is small, speed control can approach being as Basics of Web Tension Control SummaryThe capacity of the singleroll crushers is a function of the roll gap, the roll length, and the speed, and ranges from about 30 tons/h (27 metric tons/h) for a 24inchlong (61 cm) roll crushing to ¾ inch (2 cm), up to approximately 1500 tons/h (1360 metric tons/h) for an 84inchlong (213 cm) roll crushing to pass 10 inches (25 cm)Roll Crusher an overview ScienceDirect Topics
