Double roll crusher technology redefined

THE TECHNOLOGY OF THE DRC SERIES

The conventional crushing technology of a double roll crusher could not keep up with alternative crushers such as jaw crushers, cone crushers or impact crushers in terms of crushing ratio. This has changed with the help of new crushing technology.

The process-related advantages of a double roll crusher are further optimized in combination with the greatly increased crushing ratio and can thus bring significant advantages in the production process as a more efficient alternative.

Compared to the roll crusher solutions known on the market, the DRC crusher differs in that it has a higher crushing ratio and higher throughput.

A CRUSHER FOR ALL SCENARIOS

In times of rising energy prices, it is becoming increasingly important to optimize the energy-intensive processes like comminution. The entire drive train of the CST double roll crusher is designed for achieving high efficiency without sacrificing important performance reserves.

Blockages are automatically removed by an intelligent drive control. The double roll crusher is designed in such a way that the rollers can be reversed from standstill with extremely high starting torques. Foreign objects that cannot be crushed are automatically released from the crushing chamber. This is done with the help of the hydraulic gap adjustment, which can open and close the crushing gap fast. In combination with the overload protection, expensive machine damage is effectively avoided.

The combination of all the functional units mentioned enables the operator to cope with different requirements resulting from different properties of the feed material and to ensure uninterrupted production times.
