Its crushers also feature an advanced clearance system that can be used in the event of a power failure or when tramp metal enters the crusher. The push-button system works by lifting the upper frame vertically, allowing material in the chamber to fall through the crusher quickly and safely, giving the minimum of downtime.

Moreover, the difference in power consumption between the two types of machine is greater in practice than in theory; this is due to the fact that, since the gyratory crusher can be choke-fed, it is easier to keep it running at maximum efficiency.

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.

For the 1-in. screen below the roll crusher the capacity has no correction factor and the area needed is 32/2.1 = 15.2 sq ft. To handle the output from a 40 x 24 roll crusher the screen will have to be at least 24 in. wide. Perhaps it will be more effective to use one continuous screen of at least 20.1 + 15.2 = 35.3 sq ft.
