Grinding ratio (GR) is calculated as the ratio of weight loss of material to the weight loss of abrasive wheel for a specific grinding time. Although it can be ground with pure silicon carbide wheels, the grinding ratio is very low and the material is easily damaged. Although performance was outstanding, when compared with conventional aluminum ...

Grinding ratio is the quick method of evaluating the grinding wheel performance. Grinding operation removes metal very delicately, leaving a finished surface of superior dimensional accuracy and good surface texture. If it is carried out properly, there will be very less metallurgical damage due to the rise of pressure and temperature of the ...

Strip Ratio. Die Strip Ratio bezeichnet das Verhältnis Abraumvolumen zu Erzkörpervolumen. Sind für 1 m³ Erzkörper zuvor 3 m³ taubes Gestein zu entfernen, um ihn weiterverarbeiten zu können, so spricht man von einer Strip Ratio von 3:1. Somit bedeutet eine hohe Strip Ratio auch einen teureren Abbau, da mehr Volumen bewegt wird.
