Dynamic balancing of the mineral wool drum saw by correcting the knives masses

Abstract

The article focuses on the process of balancing mineral wool drum saw. The saw had had tendency to lose balance in short period of time. Balancing parameters was analysed in terms of velocity and acceleration parameters. The route of correcting mass was designed by using knives with different weights. It’s necessary to realise balancing by addition and subtraction the knives with incorrect masses. Most of balancing processes over the world are based on constant mass with additions or substations of masses, but it hadn’t possibility to realise it in that case. The aim of this article is to present an alternative method of balancing atypical rotor, which has a tendency to frequently and spontaneously change the weight distribution. The presented balancing method is also interesting, because it can be an inspiration for the correction of some rotor solutions that are not adapted to balancing, but still need this procedure.
