Our PTRF fine grinding mills is equipped with one or two rotors, depending on the application. The starting material is mineral products with a feed size of up to 30 mm, depending on the material.
The special feature of the PTRF is that the machine does not crush organic materials, which enables optimum separation downstream. Depending on the speed, grain curves and target grain size can be set.
Optimal material disintegration, separation of mineral and foreign matter
No shredding of impurities and organic matter, which can thus be easily separated downstream
Less energy required per ton for shredding compared to conventional machines
Wear parts specifically selected for the
The impact mill with one rotor is suitable for crushing minerals to 0-2 mm, 0-1 mm or 0-0.5 mm. The feed size is up to 30 mm, depending on the material.
|Feeding size:||Up to 30 mm|
|Inlet size:||170 x 510 mm|
|Final Grain:||0-2 mm|
The impact crusher with 2 rotors has as target products (<0.090 mm, <0.065 mm, <0.030 mm) which are used as cement substitutes, for foam glass, carbonates and kaolin.
|Feed opening:||Up to 10 mm|
|Inlet size:||145 x 680 mm|
|Final grain:||Up to 0,010 mm|
In the PTRF fine grinding mill, only the mineral content of the feed product is crushed without destroying the aluminum content or creating unnecessary aluminum chips. In this way, the minerals can be easily screened or sieved after the PTRF, and a very clean aluminum fraction remains. This application can be used for a feedstock up to 15 mm, for larger products a PTH hammer mill must be used.
