7. Barmac Duopactor Barmac Duopactor Barmac only make 3 port rotors in varying sizes from 12” to 40”. All rotors below 27” are for special mineral machines very small and not good for quarries. Barmac only make 3 port rotors in varying sizes from 12” to 40”. All rotors below 27” are for special mineral machines very small and not good for quarries. To get access to the rotor you need a crane to remove the lid (4 bolts) and the cascade assembly. This will take about 1 hour and two men. With the rotor out you then have to remove 27 bolts (18 are special bolts from Barmac) to change the wear parts. Wear parts are cheaper than Ore Sizer but have a life of 50 to 60 % of the Ore Sizer parts. To get access to the rotor you need a crane to remove the lid (4 bolts) and the cascade assembly.

Wear parts are cheaper than Ore Sizer but have a life of 50 to 60 % of the Ore Sizer parts. Some wear parts are cassette type but not the tip plates trail plates and deflector plates. On most rotors these have two bolts each and on the new one there are three. Some wear parts are cassette type but not the tip plates trail plates and deflector plates. On most rotors these have two bolts each and on the new one there are three. Barmac have Cascade system to bypass the feed to the rotor. This will work but only up to 12 % in Cascade. Very few machines benefit from this with some success with very week material. Most machine do not use the cascade as this REDUCES the crushing action.

8. Sandvik Merlin. Sandvik only make 2 size of 3 port rotor 33” and 39”. These rotors are very light construction and have many problems with high wear. Each tip has three bolts. There are the same number of bolts used in the assembly of there rotors as well as some need for welding repairs and balancing. Wear parts are cheaper than Barmac but only last 70 to 80 % of the life due to the fact they are smaller and lighter. Sandvik only make 2 size of 3 port rotor 33” and 39”.

9. REMco. Remco machine was developed at the same time as Ore Sizer. This is basically a good machine but more bolts in the rotor than Ore Sizer (12 more). Remco make 3,4,5,6 port rotors in 5 different sizes. Each machine is individual there are not many machines the same – customers are confused with large range of options and different rotors. When we asked the owners of Remco about this they said the idea was to confuse the customers so they were afraid to go to another supplier. They claim to be the Experts. Customer support is from California USA from one man – the owner. Wear part life is close to Ore Sizer but no new technology is coming through. Ore Sizer is now converting the last two Remco machines in Europe to Run with Ore Sizer rotors. Remco machine was developed at the same time as Ore Sizer.

10. Ore Sizer OM Series. Ore Sizer rotors are 3,5,6,7,and 8 port in sizes of 29”(3and 5 port) 35” (3,5and 6 Port) and 40” (3,5,6,7 and 8 Port) Ore Sizer rotors are 3,5,6,7,and 8 port in sizes of 29”(3and 5 port) 35” (3,5and 6 Port) and 40” (3,5,6,7 and 8 Port) All wear part except two are cassette type NO BOLTS. A total of three bolts are removed to access the rotor. Two on the hydraulic ram top and one on the side door. To remove the rotor another 13 bolts are removed and the rotor is ready for lifting out. Wear parts life is greatly increased due to new technology and continuing investment in development. Mina mum increase in life compared to Barmac is 50% Maximum achieved to date is 320%.
