ASRi


The Hydrocone has a

hydraulically

supported mainshaft

Hydrosetis the key

to success

The mainshaft is

supported by ahydraulic jack

Calibration

There are two ways of calibrating the crusher:

metal-to-metal and with lead.

The system automatically suggests calibration

with lead when it is not possible to carry out ametal-to-metal calibration.

Metal-to-metal calibration is now completely

automatic.

The operator is led through the entire processand is informed about what the system is doing.

If appropriate, warnings appear on the screen.

Crushing programs

It is possible to store up to 20 different

crushing programs.

A crushing program can regulate the

crusher in accordance with one of

three different methods:

Auto-CSS Multi-CSS Auto-Load

Much easier to define a crushing program.

In Extended mode, the user can takeadvantage of the new POT feature to

establish the optimum setting.
