Here are a few contractors that have used or own the bucket crushers all around New Zealand.
North Canterbury
We have just been to Mike Earl Contractor in North Canterbury and set up the BF 70 on a 18T Doosan Digger. This contractor has a small quarry with rotten rock and this crusher will suit him down to the ground, I called in two days later and the contractor was rapped with this machine. It was pleasing to see this machine working so well in its perfect environment. I have added a few photos of the digger, crusher and his pile of rock to be crushed. The contractor is producing about 30m3 per hour with a jaw setting of 50mm.
Christchurch City
We have been to a few local contractor in Christchurch Like Gardiner Contracting Ltd, FH, to crush their old concrete and they reused it has hard fill.
Nelson
March Construction own and are using a BF120 which is crushing old concrete and any local rock to use for hard fill on there sub divisions.
North Island
We have sold a BF90 to Mason Contracting in Warkworth. This machine is still working well recycling concrete in to hard fill and crushing the local rock in to quality material suitable for building roads and farm tracks.
Crushing Down South
I have just been down to the Otago district and set up the MB BF120 on a SH300 Sumitomo for Te Anau Earthworks & Excavations. I had a few hiccups on the set up but nothing we could not work through and sort out. The pin spacing was not quite right so we had to alter our locking plates that bolt to the side of the Multi fit top. We set and welded our new plates, so it could mate up to the quick hitch nice and snug. <!–more–> Next we plumbed the MB BF120 Bucket Crusher to the Sumitomo, this was relatively straight forward. We warmed up the crusher and got the hydraulic fluid up to temp and checked our pressures and flow we were down on pressure. So a quick call to A B Equipment Ltd in Invercargill to make sure I had the right adjustment screw on the Sumitomo and I set the pressure. I had the right RPM and back pressure & we were away crushing. With the jaw size set to 30mm we set to work and crushed away and produced an excellent product this could be used for roading base course or drainage work around pipes. The tailings that are to be crushed have all ready been over a 30mm screen and have no use, but now they are to be crushed and have got a second shot at becoming usable material. After running the MB BF120 for a few hours Production was increased by increasing the output size to 40mm and now they are crushing straight over a 30mm screen, and the reject chip will go in to a 65mm Blend which will be use for many applications. This will suit David Smith owner of Te Anau Earthworks as there are no crushing sites close by and will make cost effective Crushing.
Crushing in Akaroa
To be added soon.
Ashburton
I arrived in Ashburton to set up the MB BF70 on to Greg Donaldson Contracting’s Hitachi 160LC excavator. When I did the audit on the BF70 there was an unusual amount of back pressure we checked all our setting and they were in the right place. Hydraulink come through to have a look and they re-plumed the machine to give us a straight dump to tank which gave us our 10 bar back pressure. So with ironing these glitches we were able to start crushing. The Jaws were set to around 30mm and this caused a problem also, the material we were crushing was from the Mt Hutt area which had a lot of fines and was quite damp this caused the material to vibrate together and stick in the throat. We opened the jaws out to around 50mm. This made the crushed product flow quicker and made a good product and will still be a great base course.
Crushing Concrete Rail Sleepers
We demonstrated how well the BF60 and the BF70 could crush concrete railway sleepers. We found that with the BF70 we could crush 2 side by side in under 30seconds. The BF60 was set up on our Sumitomo sh120 and this was crushing the sleepers well also. The BF70 was set up on a Komatsu pc200 around a 20T size, we hired this of Ron Aldous from Porter Hire Christchurch. We set this digger up in under 2 hours. The demo went well and if we could load the crushers in a face shovel fashion we could crush over 100 sleepers per hour. There is about 8kgs of clean steel in every sleeper, so there could be some money in recycling the steel alone not to mention selling the crushed product.
Crushing Glass at a Recycling Depo
Recycling glass has become a problem in the way of separating out the glass from the plastic tops. We have found that when we crush the glass, most of the glass turns to sand, the tops stay complete which makes them easy separate out through a screen. There are piles of crushed glass like this one all over the country not to mention the world and our crushers can help sort this problem and save the rate payers some money at the same time. CCC TWO LTD in Christchurch have asked us to demo and the results you can see in the photos. This is the only way forward.
Crushing at Mcrae Rock Quarry
I have just been down to Temuka and set up a BF70 on A Volvo 210, Craig Mcrea will be crushing a form of rotten rock and river shingle to be sold from his quarry, this is a large quarry and the BF70 will work well in this environment. UPDATE. Unfortunately the crushers quantities at 20-40mm did not stack up, the rock may have been to hard and there may have been to many fines in the product to be crushed. Craig was happy with the finished product but it took to long to make a big enough quantity to sell quickly.
Crushing at Waikato Concrete Crushers In Hamilton
The BF70 has made it to Hamilton and was set up today on Andrew Proudlock’s 20T Kobelco excavator and will be crushing old concrete demo material and all so over 1000 Rail way sleepers (New But Rejects). We have had a play this after noon and has tackled the job head on and there is no immediate problems. We will be crushing tomorrow to see how production goes, Keep watching for my next up date.
Crushing Glass at Amberley
Today has been good for the BF60 Bucket Crusher crushing glass. Amberley has a problem like every other town around New Zealand with stock piles of glass getting bigger and bigger everyday. Last time I had an opportunity to Crush Glass I set the crusher very fine. This time the crusher was set to 20mm and the product and productivity was higher.
After we crushed the whole bottles the glass went through for a second pass which made it a finer product. After that it went through for its third pass and the majority of the product came out like sand.
The Glass can then be screened and sorted in to pile to be use for mixing in with agitate for road bases, and sand blasting.
I am happy to talk and work together with any councils to develop glass recycling in you district.
