Power Consumption of Roll Crushers. Within the same reduction ratio the power consumption of roll crushers varies widely. The power required could be expressed by the general equation (6.8) P = capacity × reduction ratio × work index. In industry, the low pressure smooth surfaced rolls are designed to draw 8–50 kW of power under dry conditions.
