Parametric Factors for the Tangential-Rotary Picks Quality Assessment / Wskaźniki Parametryczne Oceny Jakości Noży Styczno-Obrotowych

Abstract

Abstract Procedure of the quality assessment of tangential-rotary picks used in various types of mining machines, has been described in the present study. Authorial method of the quality assessment of tangential- -rotary picks based on examination of geometrical and material factors, including pick wear rate, has been discussed. The method is based on parametrical factors and the described examinations tailored to determined conditions of the machine operations, including user requirements. Testing results collected in form of measurement cards allow selection of the optimal pick, including the influence of chosen parameters into the pick wear rate.
