The Kongskilde Mixer VM is the only complete diet mixer on the market made of high-strength steel.
The steel which is used for complete diet mixers is divided into 3 groups:
1) Standard steel (st.37/S240)
2) Quality steel (st.52/S355)
3) High strength steel (S650) |
 |
Kongskilde is the first producer of complete diet mixers who has taken the step and introduced high strength steel S500/650 in the production of diet mixers.
The use of high strength steel is especially important in connection with the auger windings and the first 50 cm of the tub walls, which are the parts that are exposed to the hardest wear. |

Built to work harder and last longer
Test of high strength steel
To document the strength of high strength steel a comprehensive test program has been carried out.
At the right is the result of two test items, steel quality S355 (ST 52) and S650, respectively, which were exposed to the exact same test course. |

Test result
A weight loss which is 3 times higher gives a factor 1:3. This means that 6 mm S650 = 17 mm S355. In order to obtain the same wear resistance as the Kongskilde complete diet mixer has with 6 mm steel quality S650, it is necessary to use a 17 mm plate for the tub walls when using steel quality S355 (ST 52)!

The advantage of high strength steel S500/650
Significantly less wear on tub and auger!
Less own weight allows for increased net weight!
Less power requirement for pulling of Feeder! (important when the silage is transported from the clamp silo).
Less wear on tyres and surface.
Conclusion
Kongskilde uses a steel quality which is nearly three times more hard-wearing than steel S335 (st. 52) at the same thickness.
The tub walls on Kongskilde complete diet mixer of up to 20 m3 are made of 6 mm high strength steel. On bigger machines, the first 65 cm of the tub walls are made of 8 mm high strength steel. |
