Cold Compression Strength (CCS) Test RB 1000

According to ISO 4700ASTM E 382 and IS 8625 StandardsRB 1000 is a fully automatic systemfor determination of the crushing strength of fired iron ore pellets and reduced iron ore pellets. The equipment consists of a loading unit, with an automatic handler and feeder for the samples and an electronic unit for indication, printing and statistic calculation of crushing strength test data.

Following options are also available:

  • Load Cell for low loads (3 kN full range) for soft pellets – interchangeable with 10 kN cell – auto calibration software.
  • Continuous sample dimension measuring device for determination of crushing load by sample contraction logic.
  • PC software for crushing test data acquisition together with each test load curves data and statistic analysis.
  • Calibration system based on an external certified 10kN load cell complete of signal conditioning unit.


System Features

The loading device, with a capacity of 1,000 daN (~1,000 kg), works at constant compression speed (5, 10, 15 or 20 mm/ min). The low speed is kept only during the compression period. High speed movement of the compression plate is provided in the approach and return phases to reduce total test time.

Compression rammer and sample handler disk

The applied load is measured by means of interchangeable precision load cells that can be supplied with different full range values.
The load measuring system is equipped with an electrical self-calibration performed periodically during the test CCS values are displayed and printed both in kilogram or in decaNewton with a resolution of 1 kg or 1 daN respectively.

Electronic Unit

The electronic unit drives the compression process and provides to display and to print the crushing strength values and to calculated statistic data.
The available statistics are: minimum and maximum value, number of tests with values under different thresholds, mean value, standard deviation and variation coefficient.


The electronic cage includes a thermal paper printer for status messages and current data printing. A remote host computer interface (RS232C) is included to allow data logging and/or graphic representation of the results.

The optional archiving software RB 1000 Data Manager is available as option providing an user friendly interface to archive and graphical print out the test results.

Automatic feeder

Automatic feeder

A continuous feeder with a capacity of about 1000 samples, consisting in a vibrating pot in which the pellets can be put in bulk, is included in the RB 1000 assembly.

Operating Mode

The equipment can be operated in MANUAL or AUTO Mode.

In MANUAL mode the operator moves down the press and determines the load at which the test piece undergoes complete breakage.
In AUTO Mode the electronic unit identifies automatically the crushing strength as the maximum load in a “LOAD DECREASE CRUSHING LOGIC” or a “TIME BASE CRUSHING LOGIC” with programmable parameters.
AUTO Mode allows using the system not only for routine purpose but also as a research tool.


RB 1000 Data Manager

The RB 1000 Data Manager is an optional dedicated Software that allows the operator to have an on-line monitoring of test results and to get the print out of Test report as in the Standards.


Acquisition, archiving, printing and export of test data, together with graphical representation of the results are fully provided.
The software is compatible with Microsoft Windows© environment.

Load Cell Calibration system

RB 1000 Calibration

The RB 1000 Load Calibration System is an external comparison tool that allows the users to perform a periodic calibration of the device with a certified load cell.


All mechanical parts needed to operates with the load cell are included in the kit. The provided calibration certificate guarantees the precision of the readings.
