Columbus McKinnon Tire Chipper

This is a just like new Columbus McKinnon tire chip shredder that has a multi-stack cutting chamber. In fact we have installed new hardened rotors in this machine as part of the complete refurbishing in our shop.  This is a much better longer life rotor arrangement than came out in these machines when they were shipped new from the factory.  Another improvement we have made on these rotors is to install inserts in all the knife seats.  When the machine breaks a bolt on a knife, as they all do when a knife gets knocked off, instead of having to drill an oversize hole in the seat, welding it back full, and then redrilling and tapping the hole, you simply remove the insert with the broken bolt still inside and replace the insert.  This saves at least an hour on every hole that must be repaired.  In addition they have multi-stack cutters meaning that they have 2.2, 2.1, as well as 2.0 knife seats available to put knives on. This way you can purchase a brand new 2.2 knife and grind it down two more times using it first on the 2.1 then on the 2.0 rotor seats. This way your knife life is extended by three times. Note: In addition to this Columbus McKinnon tire Chipper we also have one that has the 1.9, 1.8, and 1.7 rotor seats thus giving you three more knife grindings. So you could actually purchase a new 2.2 knife and grind and re-use it five more times so this would be getting you six total uses out of each knife. And when they cost around $20.00 each this adds up to be a tremendous cost saving over a year's time and especially over the life of the shredder. Of course this is if you would purchase both of these refurbished chipper shredders that we currently have for sale.

This Columbus McKinnon tire shredder is powered by a 200 H.P. electric direct drive system and has a soft start in order to reduce the amperage draw on startup. This machine was purchased new in July of 2005 and after being refurbished by our shop it is just like new with the exception that the rotors are made of heat treated 4140 material rather than the normal mild steel that they were shipped from the factory with. This means that if a knife does come off while the machine is in operation and you don't catch it immediately you shouldn't harm your knife seats nearly as easily. This chipper would work ideally in conjunction with any other primary shredder that you currently have installed. Of course you will need some kind of classifier (sizing screen) and re-circulating conveyors in order to make a sized chip. This shredder will have in-feed hopper, stand, and out-feed hopper.
