1. Model: WTY-S10
2. Product name: electronic iron ore pellets compression testing machine
3. Introduction and application of testing machine
The machine is mainly used to test the properties of iron ore by the application of a compressive load to a single iron ore pellet at a specified speed of the compressive platen until the pellet is broken.
This machine adopt computer auto control, with constant test speed, constant stress, test force keeping and other control mode. The computer realize test data and test curve’display, save,manage function, can print test report. With special fixtures, can test other material compression and flexual testing.
4. Definition
Crushing strength: the applied maximum compressive load at which an iron ore pellet is broken completely, and which is expressed as the mean value of all measurements of test sample.
5. Taking of sample
The test sample (test pieces) for determining the crushing strength shall by obtained at random, for example by the use of a random selection plate, on about 1kg of the sample for physical testing. The test sample shall be oven dried at 105±5℃ and cooled to room temperature before testing.
6. Number of test pieces (iron ore pellets)
Sixty or more test pieces, or as agreed upon between the interested parties, shall be tested for each sample.
7. Test procedure
Place a test piece (single pellet) at the approximate centre of the surface-hardened portion of the lower platen. Apply the load at a constant rate between 10 and 20mm/min throughout the test period.
Record the maximum load, at which the test piece undergoes complete breakage, to at least one decimal place, in decanewtons.
Note: complete breakage is ensured by continuing to apply the load until the platen gap has closed to 50% of the average test piece size.
Clean the platens thoroughly before the next test piece(single pellet) is tested.
Repeat the procedure on the remaining test pieces.

Features and Function:
1. This testing machine adopt AC servo system drive the AC servo motor,by precision reduction gears drives the ball screw,with high test accuracy,low noise.
2. Without pressure oil leakage and proportional valve blocking, low noise, more reliable.
3. Window control and dealing software, design more reasonable.
can arbitrarily set pressure value, pressure time, auto calculate test result.
4. Advanced auto control function, can do single or batch test.
5. Auto stop,after sample broken.
6. With over load protection.
