Friction coefficient research at refining of fibrous semi-finished products

Abstract

An object of research of article is the friction coefficient at refining of fibrous semi-finished products in the knife refining machines. The main consumed energy of these machines is spent for overcoming friction of rotor about stator. On the basis of the theory of contact interaction of knives the tangential coefficient of friction between rotor and stator is investigated. This coefficient depends on type of friction of rotor and stator, concentration and type of fibrous semi-finished product, pressure in an interknife gap, the given module of elasticity of material of plate, the area of contact and speed rotation of rotor. Recommendations for decrease in power consumption of process of refining are developed. © Published under licence by IOP Publishing Ltd.
