As a retired railroad employee I'd caution against being any where close to the shredder while working as spikes , anchors , tie-plates , bolts , nuts and washers will sling out of the machine . Good that the funky junk is being burnt for fuel as that's all it's worth , that stuff will never biodegrade . Our railroad tried shredding used ties behind the tie gangs and dumped off to the side of the railroad dump , less than a year later the derailment contractor clearing a derailment got mired down in the mess and that stopped the practice of shredding ties and dumping down the dump .
Excellent method of handling railroad sleepers, they are too hard on tub or horizontal grinders and cause way too many stoppages. Its far faster and more efficient to run thru a shredder and bust them down and remove metal and then straight thru a grinder that doesnt have to cycle it just keeps grinding continuously. Very little downtime on either machine.
177k ties in the yard - equivalent to 12,500 tons. The production rate is 70-75 tons/hour. Less than 200 hours of shredding. Yes, no maintenance needed for west parts for THE PILE IN THE video.
The machine has a diesel engine so routine oil changes are required as well as hydraulic oil and filters. The shredding teeth require hardfacing to build back when they wear down.
The questions were, if all the components lasted for THE PILE IN THE Video? That a complex machine normally needs services and oil change is nothing we need to talk about.
Very impressive as that sort of material is a great test for a grinder as the material is presented to the mill in all orientations. I didn’t see the discharge diminish at all with that material. I haven’t seen one of the RotoChoppera here in in Australia at all. Very aggressive feed wheel that’s for sure.
Good question. Infeed, power feed and Position Sensor were all set at 10. The SP1 was set to 1700 (if I remember correctly) which gives us about a 300 rpm window for the variable speed hydraulic drive motors speed up and slow down based on engine RPM.
By the color of the product, it looks like the chipper is grinding up osage orange aka hedgeapple trees. if so, that is one tough machine. Osage orange trees will dull a chainsaw blade in short order.
