ASRi is a system which automatically regulates the crusher and protects it

against overloads.

ASRiTM - Definition

ASRi


The Hydrocone has a hydraulically supported mainshaft

Hydrosetis the key to success

The mainshaft is supported by a hydraulic jack

ASRi


So….., why is the Hydroset system so important?

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 a metal-to-metal calibration.

Metal-to-metal calibration is now completely automatic.

The operator is led through the entire process and 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 ofthree different methods:

Auto-CSS Multi-CSS Auto-Load

Much easier to define a crushing program.

In Extended mode, the user can take advantage of the new POT feature to establish the optimum setting.

Alarms

ASRi has an alarm monitoring system which monitors a number of analogand digital signals.

The alarm list displays the current status of an active or unacknowledged alarm.

ASRi has an alarm log which displays all status changes for all alarms.

ASRi


Event list

ASRi incorporates a system which logs a number of different events.

The events are displayed in a list where it is possible to sort events according to type or time.

Examples of events are: Switching the system on and off, starting a crushing program, calibration, etc.
