VSI Crushers

While most other crushers reduce rocks by pushing them by force against metal, VSI crushers also use the rock fed into the machine to crush itself.

  • PARTICLE FLOW MODELLING ON SPIRAL CONCENTRATORS:

    1999-11-11· The particle flow on spiral concentrators is characterised by Stokes numbers that vary by several orders of magnitude (10-1-103). In addition, particulate volume fractions decrease significantly outward across the trough from near maximum values in the inner region to dilute values at the outer radii (100-10-3). Subsequently, the

  • Fluid flow modelling on spiral concentrators ScienceDirect

    Fluid flow modelling on spiral concentrators 233 It can be seen from Eqs. 13 and 28 and Figure 3 that the surface velocity produced by the new profde is the same as that of the Manning profile at five-thirds of the mean velocity. The laminar profile produced a surface velocity of one-and-a

  • Computational simulation of fluid and dilute particulate

    It can be observed in Fig. 1 that for smaller particle sizes and greater approach velocities, higher values of ω are required to prevent sliding. Additionally, the critical angular velocity reduces as the impact angle increases. Rotational velocities of particles have not been measured on spiral concentrators so it is necessary to provide an estimate in the present analysis.

  • An analytical approach to explain the generation of

    The spiral concentrator has been extensively used in the industry for decades. Gaps, however, appear to remain in understanding and explaining its unique flow pattern. Spiral is marked by the existence of high shear rate. Gravity, drag, frictional force between particles and trough, centrifugal force and lift force act in a particular manner to generate a unique flow pattern called secondary

  • Experimental modelling and plant simulation of spiral

    Spiral concentrators (called ‘spirals’ for the sake of brevity) are helicoid troughs used to separate minerals, based on particle composition and size differences. Due to lower relative capital costs, operation simplicity and separation efficiency, spirals still enjoy prevalence in the mineral processing industry ( Grobler et al., 2016: 189 ).

  • PEPT studies of heavy particle flow within a spiral

    Usually, as the particle is closer to the centre it moves slower, but this is not what is shown in these passes. A potential explanation for pass A is a change in the depth of the particle into the primary flow. In the spiral trough, the speed of this primary flow varies with the depth (Richards et al., 2000).
