Feed-hopper level estimation and control in cone crushers
Consider the linear-geometry feed-hopper of a cone crusher and a cone crusher feed-hopper level control arrangement illustrated in Fig. 4. Assuming an even material surface and constant material bulk density ρ, the mass m of the material inside the hopper is given by m ( t ) =( t ) ρ, where A is the hopper cross-sectional area, h is the ...Web
