Shear stresses and material slip in high pressure roller mills

Abstract. The compaction of the particle bed in a high pressure roller mill causes pressure and shear forces on the rollers, which have been measured simultaneously with a sensor. As known, the pressure peak arises short above the gap neck, the shear is firstly orientated against and then in the rotation direction.Slip happens only if the shear exceeds the external friction; that means the ratio of shear stress τ and pressure p (normal stress) has to exceed the friction coefficient μ. τ/p=μ ( materials, surface structure, moisture, pressure, ). The idea of an overall slip in roller mills and briquetting rollers results from the experiences withShear stresses and material slip in high pressure roller mills
