Abstract:Background:
In order to study the loading process of shearer spiral drum, the theoretical model of
loading process of spiral drum was established based on the kinematic characteristics of coal block in
the envelope region of spiral drum.
Objective:
A spiral drum was designed for MG400/951-WD shearer, and this spiral drum was taken as
the research object, the influence of spiral angle of the blade and rotation speed of the spiral drum on
the theoretical coal capacity was analyzed.
Method:
The intrinsic para… Show more
