New Model for Predicting Instantaneous Cutting …

New Model for Predicting Instantaneous Cutting Rate of Axial-type Roadheaders Qianqian Zhang*, ... The cutting mechanism of a roadheader comprises a driving motor, a coupling, gear box and a cutterhead. The cutting power is the power consumed by the cutterhead during the interaction between the picks and the rock. This is an important index …

were recorded for different depths of cut and cutter spacings and likely net cutting rate of the roadheader exca- vating rock formation was predicted using specific energy and cutter head power. In situ cutting rate and laboratory predicted values were compared in order to test the validity of the full scale

New model for predicting Instantaneous Cutting Rate …

In this study, a new model for predicting the Instantaneous Cutting Rate (ICR) has been developed. The performance of EBZ260W axialtype roadheader has been evaluated in the laboratory artificial rock cutting tests and in the tunneling field tests. Using the model, the processes of the artificial rock cutting in the laboratory tests have also ...
