Lubrication impact on the value of friction coefficient of coffee beans sliding ever the steel surfaces of various roughness
The article analyzes the influence of steel surfaces processing quality on the value of sliding friction coefficient of Robusta and Arabica coffee beans at dry and lubricated fricbica. The research obtained coffee dry and lubrication functions and parameters of sliding friction coefficients distributions and mathematical models for determining the index which depends on the roughness of steel surfaces.
