General description
MM 6000 is a completely automatic and user-friendly equipment, able to perform tests on iron ore and coke samples according to several Standard procedures. Instrumentation is based on a Programmable Automation Controller to drive, fully automatically, the test in terms of oven and sample temperatures, reaction and purge gas flow rates and monitoring the sample weight.
The equipment accepts entry of sample data for automatic calculation of test conditions (when requested) based on the parameter values acquired by the instrument.
The System is equipped with a touch screen graphic interface (12,1 inches) with Recording and Data Logging features of main process variables.
The vertical oven is constituted by 5 independent heating zones and the control thermocouple (3 measuring points) is directly placed in the sample for a better isothermal condition during the test.
Reaction gases and Nitrogen (purge gas) flow rates are driven by high precision Mass Flow Meters with automatic selection and by flow rate control. High accuracy weighing device is installed for continuous monitoring of sample weight loss during the test.
MM 6000 features are:
- Friendly set up and controls by touch screen interface
- Accuracy of test temperature during reaction time
- Isothermal temperature distribution in the sample
- High accuracy of gases flow control
- Accuracy of sample weight (resolution 0.1 g)
MM 6000 automatic operations:
- Automatic temperature time profile control
- Gases input timing
- Gases flow rate control by mass flow meters
- Continuous monitoring of sample weight
- On line calculation of test results as reduction values
New option: REMOTE MONITORING device now available for MM 6000 Test System!
New feature now available for MM 6000 test systems: a REMOTE MONITORING device can be optionally ordered together with main equipment. This device allows a connection over internet from the Test System to the RB Automazione Service team to monitor the status of the equipment for a preliminary evaluation of maintenance level. Our staff will suggest necessary technical activities to restore standard performances of the equipment reducing service costs and downtime for maintenance.
Delivering software updates will be also easy and quick!

Vertical electric oven
The electric oven consists of a steel structure placed on a frame and including the silica insulation material. Twenty silicon carbide high temperature heating rod elements are placed horizontally in a stack and are grouped in 5 heating zones to provide separate power control.
Replacement of heating elements is fast and easy with no need of refractory maintenance so that oven life is very long. Inner high temperature chamber is protected by a quartz tube. The oven can be equipped, as an option, with a weighing system to provide continuous monitoring of sample weight during reduction test.
Control Panel
A Multi-Function Control Panel (screen dimension 12,1 inches), with function of recorder, viewer and programmer is able to drive oven temperature, gases and other events according to the test procedures.
All the messages, alarms and information on the status of the system are displayed on the Touch Screen unit.
Reaction gases mixes and Nitrogen (purge gas) are driven by electro valves and Mass Flow meter by automatic selection and flow rate control.

Multifunction and Multistandard capability
The system can be custom tailored according to Customer specific requests and to perform one or more different procedures. Standard procedures, as Reducibility, Relative Reducibility, Disintegration, Decrepitation and Free Swelling, can be selected in below table, where main parameters of processes are listed.
For each standard, proper gas mix line should be included in the control panel and, at same time, proper program, able to automatically drive the test, should be embedded. Moreover, listed of auxiliary devices as continuous weighing system and tumbler can be provided.
