The friction force is the force exerted by a surface when an object moves across it - or makes an effort to move across it.. The frictional force can be expressed as. F f = μ N (1). where. F f = frictional force (N, lb). μ = static (μ s) or kinetic (μ k) frictional coefficient. N = normal force between the surfaces (N, lb) There are at least two types of friction forces

The equilibrium level of residue left on the sand is approximately expressed as: TB P= 1 -TR P is the maximum percentage of resin that builds up in the sand (the LOI of the reclaimed sand) B is the binder addition (%) T is the fraction of binder remaining after reclamation R is the fraction of sand re-used Example: In a typical furane binder
